WRT54G Configuration Pages not showing correctly

hey guys, I have a problem

I have a WRT54g v8.0 router that I've had for about 4 years, The wireless works fine. If I connect it to a modem, I have internet, It's signal is strong and it's speed hasn't changed since I've bought it. it's a tough peice of hardware but I have trouble getting the router's configuration pages to load. Here's what happens

It asks me to login through the dialog box
the page doesn't load (192.168.1.1)
but some pages load partially, as though they're degraded
example 1
example 2
while the other pages do not load at all

I've tried upgrading the firmware through lynksys-tftp, and doing a 30-30-30 reset as well as a normal reset and the manual's reset and so far nothing works. anybody got a solution?

 

yes I forgot to mention that I've tried to access the page with several different computers and browsers (chrome,ie,firefox)

 

I did some cruising through the Linksys support forum and could only see where upgrading the firmware was the main solution except in 1 case where the poster disabled/deactivated his Comodo firewall.
Have you tried rebooting into Safe Mode with Networking? Does that make a difference?
An option, although extreme, would be to try to flash to DD-WRT firmware and revert back to Linksys firmware if you do not want to use DD-WRT. (Your router is supported by DD-WRT. http://www.dd-wrt.com/site/support/router-database )

 

I Tried that through TFTP but I can't seem to get it to connect to my router even though it is connected through ethernet with a static IP and it pingsa correctly. I'll try TFTP with a different comp as I havnt done that yet.
