Problem for Linksys Wireless-G WRT54GS Router (e125894)

Problems with home networking between desktop running XP (wired) and laptop running Vista (wi...




By MissGarbs on Nov 05, 2007

" "
I will make this as simple as possible. I have Verizon Online DSL, a Linksys WRT54GS wireless router, a Westell 6100 modem/router combo, a PC running Windows XP (wired to the Linksys router), and a laptop with a built-in Wi-Fi card running Windows Vista. I had a lot of trouble setting up the router to work with the PC and the Westell modem, but I now have the internet working on it. My first problem has to do with the Linksys router and the software that came with it. I tried to set up a home network (at least) once using EasyLink Advisor and it worked up to the point that it just included the PC. Then, I made a few changes on my computer and to the router configuration to try to get it to work with my laptop (as directed by Verizon tech support). Now, when I try to view the status of my network and add devices through the Advisor, it starts all over with the network setup. This would not be a problem (I would just set up the network again) but I have tried that and every time it says that it does not detect or support the router or something, even though my router is one of the choices on the list of supported routers and it worked it the first time I went through setup. Also, when I turn on my laptop, I am still able to connect locally to the old network (I still don't have internet access), so it must still be active. I just cannot view or change any of the properties (like the WEP key).
The second problem is that I can no longer access the router's configuration page. The default IP address was 192.168.1.1, but that had to be changed to avoid conflict with the modem, which had the same address and subnet mask. The IP address I set it to is 192.168.2.1, but when I type that into my browser, it doesn't take me to the router configuration like it used to. I've tried it bothe connected to the internet and not connected to the internet, but I get the same net results. When I enter ipconfig /all in command prompt I get this:
Windows IP Configuration

Primary Dns Suffix . . . . . . . :

68.238.112.12

So, I tried using the IP addresses listed, but nothing worked.
Finally, I simply cannot connect to the internet through my network on my laptop. I can connect to the network, but I only have local access, not internet, and I can't make any changes to the router because of the aforementioned issues. I've tried various troubleshooters and followed instructions from several websites, but I still cannot get it to work. I really need help with this. Thanks.

- Everything went smoothly until I got to B. I connected the computers to the router, reset it, and opened the browser, but when I tried to go to the router configuration page, it says that the page is unavailable or something (you know, that stupid white screen in the browser that gives obvious solutions like "Connect to the Internet"). I tried going back over everything, but nothing worked. Finally I gave up, and just undid the changes I made on the computers and connected the modem and router to the desktop the way they had been before, The modem was (still) in bridge mode and it worked with the router on the desktop before I reset the router, but after I connected the router to both computers and did the hard reset, gave up and connected everything the way it was to start with, I could neither connect to the internet nor access the router and modem configuration pages. I changed the settings on the desktop back to what they had been and tried again, rebooted the computer, did power cycles on both the modem and the router, and did another hard reset on the router, but nothing worked, So, I reset the modem, too, and just connected it straight to the computer. Now I can't access the internet with just the modem. When we got it, we hooked it up and it worked right out of the box using the factory settings, and I changed the computer's settings back to the originals, but it still doesn't work. It is possible that there is a problem with my ISP right now, as this has happened before and it was fixed the next day, but, as I was messing with it, I am not sure whether it was because of something I did.
Also, just in case you didn't know this already, the ipconfig display from my first post is what I get when both the modem and the router are hooked up and I have internet access on the desktop. They are different if I have just the modem or just the router connected. If you need those too, I can get them, but not now, as I am on a different computer (obviously, since I can't get on the internet at home anymore). Thanks for any help.

- I reset everything and tried to go through it again but when I got to entering the IP address on the desktop, it said there was already a network using the values.
So, I did it my way, which, if I remember correctly, went like this:
  1. Reset the modem and router
  2. connect modem to desktop like before (no router)
  3. Access modem configuration
  4. change modem from PPPoE to bridge mode
  5. disable DHCP LAN server (Private LAN DHCP server)
  6. turn off computer and router
  7. Insert router between modem and PC
  8. Turn on router, modem, and PC
  9. Access router configuration page
  10. Choose PPPoE as connection type
  11. Enter Verizon username and password and apply settings
  12. Check "connected" status under "Status" tab
  13. Go to "Wireless" tab, click "Wireless Security
  14. Choose disabled from menu and save settings
  15. Go back to "Wireless" tab, click "Wireless MAC Filter"
  16. Enable Wireless MAC Filter
  17. Choose "Permit Only" option and save
  18. Go back to Wireless MAC Filter, click "Edit MAC Filter List"
  19. Enter IP address of laptop into first space, save settings
  20. Exit configuration
And that was it, I believe. I turned on the laptop and went to the network connections to setup the network and I could get on the internet right then!
Anyway, thanks for the advice.

Hi MissGarbs,

Based on your post and description, it would seem that your problem is caused by:
1. having 2 routers on the same system;
2. Both routers performs DHCP server function; and
3. Both routers use 192.168.1.1 as default IP Add.

Your problems are:
a. laptop has no internet access only local network; and
b. you cannot access the router to make changes.

A possible solution. Pls back up your configurations first before attempting changes (or log them down somewhere so if needed you can revert back).

A. Power off and remove all connections to the LinkSys WRT54GS, set it aside for the moment. The objective is to verify/establish Internet connection.

Connect your desktop PC via LAN cable to the Westell 6100. Boot your desktop PC, right click on the networking icon bottom right side in your system tray, click on Status, click on Properties button, highlight Internet Protocol (TCP/IP), click on properties button (mid right):
tick "Use the following IP address"
Enter values as shown below -
IP address: 192.168.1.4
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS servers: 68.238.0.12 & 68.238.112.12
click on OK, OK, Close.

Power on the Westell 6100, give it time to sync and connect to your Verison. .In the desktop PC, open a browser. Verify that your desktop have access to the Internet, do it on a few sites. Should you have no internet access, pls seek assistance from Verizon tech support. You need not mention the LinkSys nor the laptop since you have as of the moment a single PC attached directly to the Westell 6100.

If it is all green & go, power up your laptop and boot to Windows. Remove the LAN cable at the back of your desktop and connect it to the laptop's networking port. Do the same configuration ("Use the following IP address") to the networking/LAN card of your laptop.
Enter values as shown below -
IP address: 192.168.1.5
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS servers: 68.238.0.12 & 68.238.112.12

In the laptop open a browser. Verify that your laptop have access to the Internet, do it on a few sites. Should you have no internet access, pls seek assistance from Verizon tech support again. You need not mention the LinkSys nor the desktop since you have as of the moment a single laptop attached directly to the Westell 6100. (This is of course assuming that your laptop has a networking port)

If both the desktop PC and the laptop can now connect albeit individually to the Internet, the LinkSys may now be inserted into the system.

B. Disconnect the LAN connection of the laptop to the Westel 6100 and connect it to one of the 4 LAN ports at the rear of the WRT54GS; do the same with the desktop (use another LAN cable). The LinkSys for the moment need not be connected to the Westell. So in effect you have 2 units connected to the WRT54GS. Do a hard reset on the WRT54GS, with the power on, press on the small reset button at the rear of the unit. Allow it to reinitialize. Open browsers to both laptop and desktop. Type "192.168.1.1", password is "admin" and the username is blank, verify that you can open the LinkSys Web Configuration Utility. On either the laptop or the PC desktop (assuming both can access the same page), on the setup page of the LinkSys Config, change your Internet Connection Type to "Static IP",
Internet IP Address 192.168.1.2
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
DNS servers: 68.238.0.12 & 68.238.112.12

Scroll down to Network Setup,
Change IP Address to 192.168.1.3
Subnet mask: 255.255.255.0
Disable the DHCP Server (You can have at any given time only 1 instance of a DHCP server, either from the LinkSys or the Westell, but you can also have NO DHCP server if you are using static addresses.)

Click on Save Settings at the bottom, exit, and close. Verify that the LinkSys can be accessed from any of your browsers by typing "192.168.1.3", if no; go through the procedure again very carefully. If yes, proceed to change the Default Gateway of both the laptop and desktop PC from 192.168.1.1 to 192.168.1.3, all other configurations stand.

In your laptop, right click on the WiFi networking icon (bottom right of System Tray). Click on Status, click on Properties button, highlight Internet Protocol (TCP/IP), click on properties button (mid right):
tick "Use the following IP address"
Enter values as shown below -
IP address: 192.168.1.6
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.3
DNS servers: 68.238.0.12 & 68.238.112.12
click on OK, OK, Close.

Verify that you can access/connect/ping 192.168.3; 192.168.4; 192.168.1.5; and/or 192.168.1.6 from either the laptop or desktop.

If yes, we can now connect the LinkSys WRT54GS to the Westell 6100. Remove the LAN cable attached to your laptop. Verify that you can still access/connect/ping 192.168.3; 192.168.4; 192.168.1.5; and/or 192.168.1.6 from the laptop even without the LAN cable since you are now connected via WiFi.

If yes, connect that LAN cable to the Westell 6100 LAN port, move the other end from 1 of the WRT54GS ‘ 4 LAN ports to the WAN likewise at the rear of the LinkSys.

Verify that you can access the Internet from either computer. At this moment, you have not assigned a security method (WEP, WPA, MAC Filter). Your choice as to what security you want implemented but offhand I would suggest the simplest, MAC Filter since any other would affect speed of your connection.

Additionally, you may want to enhance you browser connection. In Mozilla, click on Tools, Options, Advanced tab, Network tab, Settings button, tick "Auto-detect proxy settings for this connection, OK, OK;
In IE, Tools, Internet Options, Connections tab, LAN settings button, check "Automatically detect settings", OK, Advance tab, check Use HTTP 1.1 through proxy connections.
In Opera, Tools, Preferences, Advanced tab, Network, Proxy server buttons, check "Enable HTTP 1.1 for proxy, OK, OK.

Normally (and perhaps easier for some) would be using the DHCP and not using static. Experience has shown me that static proves to be more stable especially if WiFi is concerned and in your case, only 2 PCs.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

- Hi again,

Per you 2nd post, that would indicate that your Westell 6100 is connected to the Internet and is doing its job of sharing the connection to your desktop and to your laptop. I am assuming that both units can connect and access the Internet. the problem is when your router is connected in-between the Westell and either or both of your PCs.

Pls do the A again just to verify that you can still connect to the Internet with either PCs.

To do a full hard reset on the LinkSys, you need to press on the reset button for more than 5 seconds or till the led indicators blink. Momentary pressing only re-initializes or reboots the LinkSys.

Pls post back results.

Cheers.
