Router webpage does not load correctly

Question

I own a wireless WRT54G, which has worked fine in the past. After setting up a new wireless network, I went to the router webpage to open some ports. The problem with the page loading is that it doesn't display correctly. No clickable text is displayed on the top of the page or the side bar, so I basically can't do anything whatsoever to configure it. I've tried loading it up in both Firefox and Internet Explorer, with IE saying the page loaded but with errors. Any help would be much appreciated.

Answer 1

I did not understand what you meant when you said   "After setting up a new wireless network".   What new wireless network did you set up?
To view the router's web pages:
Use Internet Explorer, it usually works.
JavaScript must be enabled.
Use a computer that is wired to the router.
In the non-working computer, temporarily turn off your software firewall.
If you are using Zone Alarm, right click on the ZA icon in the system tray (lower right corner of screen) and then click "Shutdown ZoneAlarm", and see if this fixes your problem. If this does not work, try the following with Zone Alarm: Open the ZAISS control center, go to Privacy, then temporarily turn off Ad Blocking and Cookie Control, and see if that fixes your problem.
If you are using Noton Internet Security with the Add-on Pack, be sure to turn off the Pop-up Blocker. Some users have reported that they needed to uninstall the entire Norton Add-on Pack.
If you cannot get anything at 192.168.1.1 then perhaps this is not your router's address. Go to "Start" > All Programs > Accessories > Command Prompt.
A black DOS box will appear. Type in "ipconfig" (with no quotes), then hit the Enter key. Look at the "Default Gateway". Is it 192.168.1.1 ? Point your browser to the "Default Gateway", then login to your router.
If the above fails, disconnect your modem from the router, and try again. If this corrects your problem, then most likely you have a "modem-router" rather than an ordinary modem. Check to see if your "modem-router" is using the same 192.168.1.x address space as your Linksys router. If it is, then report back with this problem, and also state the make and model of your modem-router.
If all of the above fails, power down your entire system, unplug it from the wall, wait one minute, then power up and try again.
If all of the above tips fail, then reset the router to factory defaults: Power down the router and disconnect all wires from it. Wait one minute. Power up the router, allow it to fully boot (1-2 minutes), then press and hold the reset button for 30 seconds, then release the button and allow the router to reset and reboot ( 2-3 minutes). Power down router. Wait one minute. Connect one computer, by wire, to a LAN port on the router. Boot up system. It should work.
If the reset does not fix your system, then you need to download and install (or re-install) the latest firmware for your router. After the firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
