Net result after all these changes.... Cannot connect to the internet from my Laptop. Sometimes will say "limited or no connectivity" My connection to the router and to the network seems to be fine (I think) but it will only sporadically connect to the internet. It has connected a couple of times for a short time but then loses connection again. I tried to run system restore to several previous restore points but nothing has helped. It seems that .net framework is also corrupted because I cant uninstall it or reinstall it becuase I get an error that says "The patch package could not be opened"
I am running WindowsXP sp3 with a wireless D-Link Router.
Am completely lost and would appreciate any suggestions.
Update: While writing this I rebooted the Laptop and got a different IP Address with no Defalut Gateway and was unable to ping the Desktop. I was able to ping the desktop before I rebooted. A desktop and the Laptop are all I have on the network
