Last night, I was playing Counter Strike: Source for quite a long period of time. I've had no problems with my internet connection until last night. Around 10-12, my internet starts giving me HUGE lag spikes. Now, I live in a 5 man house, with a WEP secured wireless network+ MAC filter, so usually when I get lag spikes like this, it's because of my roommates. Anyways, I check around the house to see that they're all sleeping, so I reboot my computer. After I reboot, to my horror, my internet connection has stopped. I can't load any web pages, connect to any servers, nil. So I took a few minutes in trying to identify the problem: 1. Changed the network card in my computer in case it was a hardware issue, still did not work. Not a hardware problem. 2. Used the same ethernet cable on another computer in the vicinity, and the internet worked. Not a cable problem. 3. Internet worked for everyone in the house, wireless and cabled. Not a router or ISP problem. So I assumed it was a configuration problem in my computer. I tried using a wireless receiver via USB and it STILL did not pick up a signal. I tried readding my connection, but was stuck with a message saying that it was a problem in my configuration. Now, I'm stumped as to what to do and how to do it. I don't want to waste 100 bucks on a networking technician so I'm putting my trust onto you, TechSpot, to deliver me from my problem. Thanks in advance for everything and sorry if my English is not good.
