Welcome to Our Website!

The original copy of this was created in September of 2010. I got my newest PC Feb 24th, 2016. After setting up the new 'Puter, and installing Win10, I then installed Avast. The first scan by Avast told me that my Network was corrupted because of a fault in my Netgear Router.

Now, after wasting half of my day off on this "Problem", I find what I suspected... it ain't really a problem!! Well, at least not from the outside sources. The "Hacker" has to be on the inside with access to ReadyShare. Your network would have to already be hacked from within for it to be exploited unless remote management is enabled.
Refer:  ReadySHARE vulnerability

Netgear Cmmunity This router was declared End of Line (EoL) some time ago, the last firmware released in December 2013, with the SOAP security issue reported 14 months later in 2015. While this may be a disappointing outcome for you, this approach to EoL products is in line with common business practice for home grade networking devices.
Looking for it - see http://www.netgear.com/landing/eol.aspx - it appears that all the WNDR3700 versions have an end of life (EOL). Even the latest version 5.
There are steps you can take to ensure that the vulnerability has no impact as described here http://kb.netgear.com/app/answers/detail/a_id/28393/~/netgear-product-vulnerability-advisory%3A-readyshare


  Brick making

Allllrighty now. Let's make Bricks. That is exactly what you will do 'IF' you do not properly investigate, lookup and examine 'ALL' the details neccessary to mess with one of these Routers. Be it this one -or- any other. Semi-Bricks are usually recoverable. Bricks can, and do, become Boat Anchors. In my very first experience, with my own Wireless Router (I finally got one), I created a Semi-Brick. Don't think what I did should have been a problem -but- it was. I had in the past helped setup Customers Wireless with no real problems. This time, it was my own and ... bam! Fortunately, for me, I had just purchased it at Fry's Electronics and they graciously took it back and gave me another one. (Yes!!... I recommend them.)

Reiterating from the VPN Case Study Site (which I quote or refer to in many places)
REMEMBER, you are here on this page because you could NOT install correctly. Therefore, read it all and refer to the references for items that I did not make clear enough.

    I recently had the need for a Wireless hookup. Through my adventures here in these WebPages I have talked about customer's machines, which were laptops. I had to check them out and -all- of them had Wireless Internet connections built in. Fortunately, some of my neighbors have Wireless connections -and- they don't have them passworded... or at least they didn't. Now most of them have passworded their access, or they have moved. At any rate, Wireless access isn't easy anymore. On top of all that I got a Wii for Christmas. It has Wireless capabilities built in -and- my daughter is signed up with Netflix which happens to have a setup to get movies thru the Wii. Whew! Anyway, that is my main reason for the Wireless connection.

    Now then, I have been Fat, Dumb and Happy (and Secure) with my hard wired setup. Now with this Wireless thingy I am gona have to setup proper security. I wouldn't mind if the neighbors "borrowed" some of my bandwidth -but- now-a-days you can't trust anybody. And I don't want anyone snooping around in my data. So I'm gona be stingy and lock it up.

(Darn... I'm gona have to edit my Network Layout Drawing. Haven't touched that in years!!)

A lot, most of, what I got here came from: speedguide.net    -and-   Small Net Builder
I like what they said and I don't want to loose it. I have modified, or re-worded very little.

Package Contents

  • N600 Wireless Dual Band Gigabit Router (WNDR3700)
  • Stand
  • Ethernet cable
  • Smart WizardTM installation CD
  • Power adapter, localized to country of sale
Refer: Netgear Site and WNDR3700 FAQ with info at Netgear WNDR3700



The 3700 comes in a new form factor that can sit horizontally on a desk or vertically on a supplied stand. There are also wall-mounting slots on the bottom. The internal printed circuit "metamaterial" antennas used in previous NETGEAR 11n routers are still used, however. But, contrary to what some may think, they don't negatively affect wireless performance.

The 3700 implements the standard NETGEAR router feature set with a few new tweaks:

WAN Support - Types handled include Static and Dynamic IP, Other (static and dynamic IP), PPTP (static and dynamic IP) and BigPond. There is no specific PPPoE setting, so you might be better off using the Setup Wizard to set up your WAN connection. WAN MTU is set separately from the connection type (WAN Setup page) and applies to all WAN options. WAN port MAC address spoofing is supported only for Static and Dynamic connection types.

The dual-band wireless functionality of the WNDR3700 is its most impressive feature. It allows you to run both 2.4GHz 802.11n and 5GHz 802.11n wireless bands simultaneously. The speed and distance of the 5GHz band is much better than the 2.4GHz band, and there is less interference. You have to set up both networks with different names, and each network can have its own security level (up to WPA/WPA2, TKIP and AES) and a different password. Additionally, you can set up guest access for both types of networks - letting users access the Internet, but not the local area network.

Firewall - The SPI+NAT firewall is pretty basic, although you can disable SPI. Both port forwarding and triggered port forwarding are supported. You get a rather short pick list of services in the Port Forwarding add screen, but you can specify the port numbers and protocols directly for both the outbound trigger port and inbound port range.

Ports can also be opened automatically via UPnP NAT Traversal (enabled by default), but at least you can log into the admin interface and see the automatically opened ports in the UPnP Portmap table. A single DMZ IP is also supported and you can disable the SPI portion of the firewall.

The WAN Setup page holds the SPI Firewall Disable (default unchecked), DMZ, Respond to Ping on Internet Port and MTU settings. There is also a NAT Filtering option (default "Secured") that isn't explained very well in either the online help or user manual.

The Block Services (outbound port filters) can be applied to all, one or a range of IP addresses, but not MAC addresses. They also can be controlled by a single rudimentary schedule (checkboxes for days of the week and one set of start / stop times).

The Block Sites feature is keyword-based and applies to web traffic only. You get an attention-grabbing red and black "Web Site Blocked by NETGEAR Firewall" page when you trigger the block and the ability to have one "trusted" IP address that can bypass any blocking.

Dynamic DNS clients - Only Dyndns.org is supported

Logging and Reporting - Logging seems mainly focused on logging web traffic. Everything goes into one log, with no filtering provided. You can clear or email the log, but there is no syslog or SNMP trap support. Email authentication has been added, but there is still no Test email button or ability to handle SMTP servers using secure connections or to specify an alternate SMTP port.

Other features - The DHCP server can be disabled and allows IP address reservation by MAC address. RIP direction and version (1, 2B, 2M) can be controlled and static routes set.

QoS: Simple four-level priority-based QoS for upload (Internet-bound) traffic has been added. You must specify the uplink bandwidth. QoS priority can be set by Ethernet port, client MAC address or application port. There are 18 pre-built QoS Policies for applications or you can define your own rules.
Note that this is not Automatic Quality of Service, as NETGEAR claimis on the 3700's web product page (Overview tab).


  Setting up the Router and your Cable Modem

For the router installation, you can follow the Resource CD that came with the unit or, if you are an expert, simply do a manual setup using router's IP (most units have an information sticker affixed to the bottom of the router). (Smart Wizard requires a Windows OS.) If you have your PC set to automagically run an installation CD, insert it into the drive, then you will see the list of tasks and info on the first page displayed. The first task is "Setup". However, you might want to select "Documentation" first and read over the steps involved. There is lots of good info in the Docs... even for the experts. Annnddd... there is lots of info on that Bottom Label.

It is a "must"... that a PC/Mac connected with an Ethernet Cable... is used to setup the router for the first time. NO exception to this!

For PC Users, use the "ipconfig" command to make sure the PC is getting a proper IP from the router.

The following was borrowed/copied/stolen from the VPN Case Study Site Web Page. I don't want to loose it and I would like to help and share with others. To conserve space and not steal everything, I have not included the Mac Portions. Please visit their site.

Quick Check LIST
  • Broadband (Cable) modem * (w/ ethernet out)
  • Router - (For this discussion, one from Netgear.)
  • PC User with ethernet adapter **
 * If you only have USB ports on a broadband modem you MUST replace it with an ethernet capable broadband modem.
** You will not be able to setup a router with a wireless adapter. You must have an ethernet adapter installed or a properly functioning ethernet adapter.

 Note   Most, if not all, of the newer PCs come with Integrated Network circuitry. That means it will have an Ethernet connector on the back of the machine. IF you purchased one of the lesser expensive models that does not have an Ethernet connection, then go to your local 'puter store, purchase a NIC (Network Interface Card) and install it.

Presented is a copy of their check sheet that you need to Print out and then Fill out so you have all the information before starting. Check List

Now then, as stated on the VPN page, you are trying to get connected to the Internet. Your ISP will have provided you with the necessary information to get connected. One of these pieces of info is a Public IP Address. This will be the address of your modem - from Cox, or whatever cable company you have. Your computer will get its IP Address from the Router. That is the purpose of it, the Router. You are provided one(1) address that can become many. All of yours will have an address of 192.168.xxx.xxx. This is the Private IP Address range. These can not be used out on the Wide Area Network. Only on your local Network.

     The WAN and LAN     DO NOT    have the same address.

DO NOT CASCADE ROUTERS. HAVE ONE MODEM, ONE ROUTER, ONE COMPUTER FOR THIS SETUP. The many come after you get connected. Connecting two, or more, Routers together involves Double NATing and that is involved. More complicated than you need ... at the start. That is for later when you are in expert status.

Annnddd... in speaking of addressing. Yours will possibly change everytime you sign on to the Internet. Cable companies use Dynamic IPs. DHCP (Dynamic Host Configuration Protocol) Yes, if their systems stay up for a long time, your address may appear to be the staic. However, it is not, and can change at any sign on. So do not use static in your setup. Static is not available for Home Users. Only for Businesses. Both your WAN IP and DNS should be Dynamic.

Now then, what to do When/IF the Smart Wizard finds the connection as a Static IP?? One way is to input an IP that is not your LAN IP. Do not do an ipconfig and put same IP range on LAN side and WAN side (internet).

So you can follow, use the information below: -IP Address -Sunbet Mask -Gateway - DNS Server

Save this info. Once this is saved, you will NOT get connected to the internet, since this is fake info. Log back into the interface of the Router and go to Basic Settings ("Router Setup" page(on CD) will explain how to login -or- you can look down below)

Change both IP and DNS to "obtain automatically".

After saving the new settings, power off both Cable Modem & Router. Unplug the Ethernet Cable between Modem and Router.

Start your network in the correct sequence.

Failure to start or restart your network in the correct sequence could prevent you from accessing the Internet.
  1. First, plug in and turn on the cable or DSL modem. Wait 2 minutes.
  2. Now, plug the power cord into your wireless-N gigabit router and into a power outlet. Wait 1 minute.
  3. Last, turn on your computer. It might take several minutes for your router to establish a connection with your computer and your Internet provider.

Verify that your router is connected correctly by checking the wireless router status lights. Log back in the router and check router status. It should show IP from your ISP.

To access your router:
1. Connect to the wireless-N gigabit router by typing http://www.routerlogin.net in the address field of your Browser, and then press Enter.

You can connect to the wireless-N gigabit router by typing any one of these three URLs in the address field of your browser, then pressing Enter:
    • http://www.routerlogin.net
    • http://www.routerlogin.com

You should get a login window. The default username is admin and the default password is password. Please notice that both are in lowercase. These can be changed and for security reasons I highly suggest that you do... make them personal.


  Changing the Built-In Password

  1. Log in to the wireless router at its default LAN address of http://www.routerlogin.net with its default user name of admin, default password of password, or using whatever password and LAN address you have chosen for the wireless router.
  2. From the main menu, under the Maintenance heading, select Set Password to display the Set Password screen:
  3. To change the password, first enter the old password, and then enter the new password twice.
  4. Click Apply to save your changes.


  Wi-Fi Protected Setup (WPS)

This is one of the Buttons on the front of your Router. For most of us 'home' users, I don't believe that this will be of much use. (I may change my mind after further investigation and studies.) The 'Guest Account' is satisfactory for most of the needs for allowing someone else access to your Network. All they can do is Access the Internet, which is probably all they wanted to do anyway. Been secure all these years, I really don't want to open the Barn Door.


 USB:  Whilst investigating, AFTER I made the first one a Brick, I found an Ausie Forum discussing this router 'before and after' it was released. There were complaints of 'dropouts' that were numerous. Turned out to be the falt of the USB connection. So, beware of what you connect to the USB port on this router.

 Placement:  The wireless router lets you access your network from virtually anywhere within the operating range of your wireless network. However, the operating distance or range of your wireless connection can vary significantly depending on the physical placement of your router. For example, the thickness and number of walls the wireless signal must pass through may limit the range. For best results, place your router: As close to the Center of your area, High as possible and avoiding other electical devices, such as fans, cordless phone bases, microwaves ... etc.

  Restore Factory Settings

You can restore to the factory default configuration and reset the router's user name to admin, the password to password, and the IP address to www.routerlogin.net. This procedure erases your current configuration, including your wireless security settings, and restores the factory defaults. When you log in after resetting, the Smart Wizard configuration assistant prompts you to configure these settings.

To restore the factory default configuration settings:

  1. IF this is your own Router and IF you care about the current settings, write them down. This would include the:
    • IP Address
    • security key
    • opened ports and services
    • Passphrase
    • etc...
  2. Use a sharp object, such as a a paper clip, to press and hold the Restore Factory Settings button, located on the bottom of the router (The hole to the button is circled in Red.), for over 10 seconds and the Power light turns to blinking amber.
  3. Release the Restore Factory Settings button, and wait for the router to reboot. The factory default settings are restored so that you can access the router from your Web browser using the factory defaults.
  4. NOTHING is said about re-loading any software... just a reset. So don't ... unless directed by a factory tech.

    The Local gateway IP address will be when reset.
    The Local DHCP range = -to-


  Linux DD-WRT

DD-WRT Main Page    Installation of DD-WRT

    DD-WRT is a third party developed firmware released under the terms of the GPL for many ieee802.11a/b/g/h/n wireless routers based on a Broadcom or Atheros chip reference design.

    A usefull command that I learned about on the Forums:
   /sbin/lspci -nnk
Think I have used it before, but like a lot of other things ... forgot about it. And we have:
I'll have to check as to why one is a straight '/sbin' and the other is '/usr/sbin'.


  Security Encryption (WPA-PSK + WPA2-PSK)

Main reason this is here is to help clearify the "Encryption Key". In changing my Linux Desktop from KDE4.x back to KDE3.5, I got this inquiry about my Wireless Network ( which I never gotin KDE4.x). Part of the information that it wanted was the Encryption Key. What it really wanted was my PassPhrase. Don't know why they can't use the same terminology. I had to sign out of Linux and re-boot into Windows in order to use the Router Program and get this info. The way to use it in Linux is probably right in front of me, but I haven't seen it yet.

This selection allows clients to use either WPA (with TKIP, broadcast packets also use TKIP.) or WPA2 (with AES). If selected, encryption must be TKIP + AES. The WPA PassPhrase (Network key) must also be entered. To reach maximum wireless performance, the 11N clients must connect to this router using WPA2-PSK(with AES) . For clients connecting in WPA-PSK( with TKIP), the maximum wireless speed will be at 802.11g. Enter a word or group of printable characters in the PassPhrase box. The PassPhrase must be constituted of either 8 to 63 ASCII characters or exactly 64 hex digits. A hex digit is one of the following characters:
0, 1, 2, ..., 8, 9, A, B, C, D, E, and F.


  Clearing the Passphrase

This addition came about cause of my "First" Wireless connection. Well, actually it was my second. The first was my Wii.!! Anyway, it was my first connection with a computer. My Son's Laptop, an Acer Aspire One ZG5. He had "somehow" deleted his sound and he claimed that he couldn't get on the Internet ... again. Well, I had just industriously worked on and setup my new Wireless Router. So, after the Wii, I tried to sign on with his Laptop ... and ... was successful! The first time!

Now then, the problem, and the reason for this section. My Son was going to sell this Laptop. Ok, -but- it had my Wireless Network Passphrase on it!! Hmmmmm??? So, as usual, we go to the Net and see what we can do about it. Couple of checks and the following procedure was found. Needless to say, the Passphrase was not just changed ... the whole entry was removed. Now I do believe, from what I read, that there have been, and probably still are, "options" to 'Save' or 'Not Save' the Passphrase after connecting. However, on my Son's Acer it was NOT an option. It just saved it. So, you might want to keep an eye on this as your friends and neighbors visit with their Laptops, iPods and other stuff.

There is a "Guest" account setup for "My New Router" that I will have to learn so I won't have to worry about this in the future.

Things You'll Need:

  • Windows XP
  • Wireless network password
Difficulty: Moderate


  1. Open the  Control Panel   via the Windows  Start   menu. Select  Network Connections.  

  2. Right-click  Wireless Network Connection  . Select  View Available Wireless Networks  .

    Click "Advanced..."

    Now then, I must expand on this. At this point you are going to be looking at the:
          "Choose a wirless network"
    screen -or- window. The "Advanced" selection may not be just the word Advanced. On my Son's Acer Aspire Netbook it was under "Related Tools" and was called:
       "Change advanced settings"

  3. Open the  Wireless Networks   tab. Under the  Preferred Networks   section, highlight the network you want to Change -or- Remove. This is a list of networks your computer is configured to automatically connect to (the passwords are saved). Click "Remove" to remove your home network. Click "OK" and navigate back to the "View Available Wireless Networks" window.

  4. Only perform this step IF you are changing the Passphrase.

    Select your 'home network' from the list of available networks and click  Connect  . You will be prompted for the new password -or- passphrase -or- a network key. Enter it and select "Remember this network." ( That was NOT a selection on this Acer...-BUT- it remembered it anyway!!) Click "Connect." Windows XP will now remember the new password and automatically connect to the network whenever in range.


  Cox Cable DNS Servers

The following is a list of Cox Data Name Servers (DNS) that are available to the states listed. It seems, as someone else observed on DSL Reports, that Cox is consolidating a number of their servers. These are the ones particular to my needs. For more info, check out the site listed below.

•cdns1.cox.net [] (Arkansas, Arizona, California, Connecticut, Louisiana, Nebraska, Oklahoma)
•cdns2.cox.net [] (Arkansas, Arizona, California, Connecticut, Louisiana, Nebraska, Oklahoma)
•cdns3.cox.net [] (Arkansas, Arizona, California, Connecticut, Louisiana, Nebraska, Oklahoma)
•cdns4.cox.net [] (Arkansas, Arizona, California, Connecticut, Louisiana, Nebraska, Oklahoma)
•cdns5.cox.net [] (Arkansas, Arizona, California, Connecticut, Louisiana, Nebraska, Oklahoma)
•cdns6.cox.net [] (Arkansas, Arizona, California, Connecticut, Louisiana, Nebraska, Oklahoma)

  Glossary of terms

These are here for Quick Reference. Probably will also be in my main Glossary, -but- they will be here where needed.

Bridged Mode
Digital Subscriber Line - A high-speed Internet-access connection that works over telephone networks and is available from 600Kbps to 26Mbps. Your maximum speed depends on your distance from the telephone provider's central office.
Network Address Translator is the translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside.
In computer networking, the process of Network Address Translation (NAT) involves re-writing the source and/or destination address of IP packets as they pass through a router. NAT allows multiple hosts on a private network to access the Internet using a single public IP address.
Now then, I use Bridged Mode in my VMware setup. Each Virtual machine is like having another computer. Therefore, I have a LAN right here on my one(1) PC. Think about it...
Also see: Wikipedia and GoToMyVNC
Service Set IDentifier - is a name that identifies a particular 802.11 wireless LAN.
Also see: Wikipedia
T-1 Line
Please see: Data Comm for Business

Virtual Private Network is a private data network that makes use of the public telecommunication infrastructure, maintaining privacy through the use of a tunneling protocol and security procedures. The idea of the VPN is to give the company the same capabilities at much lower cost by using the shared public infrastructure rather than a private one.
Also See: Netgear FAQ
Wired Equivalent Privacy - is an easily broken security algorithm for IEEE 802.11 wireless networks. Introduced as part of the original 802.11 standard ratified in September 1999, its intention was to provide data confidentiality comparable to that of a traditional wired network. WEP, recognizable by the key of 10 or 26 hexadecimal digits, was at one time widely in use and was often the first security choice presented to users by router configuration tools.
Also See: Wikipedia
WiFi Protected Setup - is a standard for easy and secure establishment of a wireless home network, created by the Wi-Fi Alliance and officially launched on January 8, 2007.

I have tried to include enough information on this WebPage for anyone to setup their system with a Netgear WNDR3700 Router and possibly the Netgear WNDR3400. IF and When I find more info, it will be added to this page. More Routers may be added -but- only IF I get to work on them. For the most part, I don't put stuff in my WebPages unless I get to play with it/them.
