Hello friends, im having a few problems with my router and i need some help. I have 3 machines in my house, a PC and 2 laptops, they are both compaq. I set up a wireless connection long time ago and i always had the same problem, everytime i turn on one of the machines i need to reset the router (the lil button on the back) to get a valid IP adress so i can use internet, it happens everytime i have to turn on the computer, or after reboot and so... the big problem is that the new laptop uses windows Vista, the other 2 computer uses XP. There's no way i can get a valid Ip Adress, not even resseting the router, the wireless connection panel of Vista shows that the computer is connected but i cant access internet, i dunno whats going and i've tried to do everything i can, set up new connections, reseting settings, changing everything, i just cant connect to internet. THe laptop is a Compaq C700 Series, the other one is a Compaq V3017La and my Pc is a P4 3.2 ghz 2gb DDR 400, 160 Hdd, 6200 Nvidia 128 mb
