I recently retrieved my laptop back from the shop for a hardware issue (problematic screen). I discovered that I am now unable to connect to my wireless network at home. The wireless network appears and registers that I am connected, but am unable to connect to the internet (webpage is not available).
Other computers are able to connect no problem (my old powerbook for example). Now what is curious about this issue is that when I plug the ethernet cable into the laptop, I'm able to connect via wired and the wireless network. In that, after I connect to the wired connection and switch to the wireless, and unplug the ethernet cable, I'm suddenly able to surf the net no problem via wifi.
Once I restart the computer, however, the problem resurfaces and if I want to connect via wifi, I have to do the aforementioned solution over again.
I tried a number of things: updating and upgrading from 11.04 to 11.10 and reinstalling my wireless driver. Neither of these things resolved the issue. Someone please help! Clearly I'm not the most technologically savvy, but am willing to stretch my mind a bit to try to resolve this finicky issue.
