Well i just today reformatted my old computer of XP to Windows 7 RTM.
I installed it with no problems and then i couldn't install some drivers as they were not updated and could not be compatible with windows 7 such as the AMDk8 Processor.
The PC already has a wireless adapter connected to it and when i was searching for my router, it picked it up with full connection and it connected. but it said no internet access. (Using a Atheros AR5005g Adapter; TP-Link) (Modem is Iconnect 622; Router is Asus)
After trying to find a solution for the wireless, i tried downloading an updated driver, yet nothing found. So i left the computer for about 3 hours and when i logged on the internet was connected. This lasted for about 3 hours and during this time i was deleting the Windows folder from the backing up from the XP.
When my modem synced out, i reseted the computer and also the modem and when i logged back on, it went back to it's original state of being connected but having "no internet access".
I'm not sure if what i deleted caused the issue to return, but just wondering if anyone have the same problem or can find a solution.
