Hi!
I have a really wierd problem, time to time (daily) i need to change my internal IP in the windows ethernet adapter settings, if i don't change it a lots of programs can't connect to the internet/servers (teamspeak, and games like Counter-strike, Guild wars....). When this happens i change my internal IP and it works again. (example : from 192.168.1.20 to 192.168.1.21. I can't use the same ip twice). I use fix IP because its easy to change it that way. I tried to reinstall the windows, and it was good for ....~ 2weeks. And now it started again. I tried to use other dns than my providers, so i use the google dns 8.8.8.8 and i tried the openDNS too.
I dont think its a router problem because the other PCs work fine.
Any idea what causes this?
