I run a wireless network, three computers. Two of them are connected and working properly to my network and the third a dell laptop with built in wireless card is not working properly. It says i am connected to my network and signal strength is excellent. However, it does not receive any packets, it sends them out slow also. The speed is 54.0 Mbps. I haven’t installed any new programs, drivers or updates. I have tried several things, like checking my router settings (which are fine) and checking my ITP protocol which is also fine. I haven’t downloaded or installed any new programs, updates, or drivers. The computer worked before when it was the only one using the wireless network, after introducing a second computer it worked a bit longer, then stopped. The third computer was added after and works fine. I need an answer please!!! Help!!!!!
