I have a basic Cisco wireless router that has problems when we try to connect 2 laptops to it via a wireless connection. It is fine with only 1 PC connected. The first PC is Windows XP, the other one is Windows 7. The XP machine is about 4 years old, the Win 7 machine is 7 months old. We also have a Linux box that is connected to the router via a cable.
With 2 PCs connected there are times when the connection is dropped. Or it takes a very long time to connect as the 2nd laptop. Also I noticed that even the wired Linux box runs into problems when the laptop has problems.
How old is it? I don’t think I’ve gone more than 2 years without having to replace one. They’re not exactly the most well-built electronic items, and they’re on 24/7.
edit: try updating the firmware on the router, first. maybe that will help things.
