Hi, I have a wireless router with 12 computers on the network. 1 computer is wired, the rest are wireless. Everything was working fine until 3 computers that were working fine before decide to stop working at the same time! I have reset the router, checked the settings, reinstalled the software on the PC's moved the PC's closer to the router...I've tried everything, but I am still getting the same problem. I wired the PC's up to the network and that works fine. The PC's also have no problem connecting to a different wirless network. What the hell is wrong with it!?! Help! Gary The three laptops that aren't working are using a netgear wireless PCMCIA card. Maybe a coincidence but all other machines on the network use a different network adaptor. Have checked all IP settings. They computers on the network are set to automatically detect setting. Have tried setting them up manually to no avail. I hate wireless networks!!!!!!!!!!!!!!!!!
