I am having difficulty solving this problem. At the beginning of last week, my computer, which is receiving a wireless signal, worked perfectly. Everything was able to access the internet without a problem. However, after returning home, I have found that Internet Explorer, Instant Messenger, and a plethora of other programs no longer connect. The only thing so far I have found to connect is Steam, which I use to play CounterStrike. This proves that the signal is there and I am receiving it. Any suggestions on this matter would be greatly appreciated. Thankyou.
