My Windows Vista SP1 laptop is set to hibernate when pressing the power button. When I come out of hibernation, if I am still at the same location...I cannot get on the network. The only way I can get it going again is to restart the computer. I have tried to release and renew using ipconfig on the cmd prompt. I have tried using the crappy repair features on the network connection page and I have tried disabling and re-enabling the hardware switch for the wireless adapter. None of these have worked! I am out of ideas other than rebooting every time. Kinda makes the whole hibernation thing a waste of time. I also thought it was my router, so I replaced it. I have the problem whether I am at work or at home (or at customer sites). If it hibernates and comes out of hibernation on the same network...I have to reboot.
