"it hasn't given me any problems until"
The lesson here is simple. Don't fix things that work. Now go find that old firmware and install that. Good luck,
I have a WRT54G v8.0 wireless router and it hasn't given me any problems until I updated my January 2009 firmware to the most recent July 2009 firmware.
After updating the firmware, my router would not connect to the DNS server. As a result, I cann't access the internet with my router. I did a hard reset and reset to factory defaults, and I tried to upgrade the firmware again, but it still doesn't want to connect to the internet.
I am on Windows 7 and I am using a Speedstream 5100b Modem.
Any help is appreciated.
