yesterday, I had a problem with the internet. I could work with the internet everday, and I had no problem with it at all. I get the internet from the university, so there is no problem with that. when i turned on my computer today, I couldn't work with the interent, and I tried all the 3 computers and they didn't work either. I tried to see if my neighbor has a internet and they said they are connected to the internet. In our apartments, we can't use wireless internet, so I went to check if anyone using it. I went to the IPConfig and saw another user name in there. How can i find out, if someone else is using wireless.
