Alrighty guys, hopefully you can help me with this problem. I work for a Circuit City, and here's how the network is setup for the computers and display computers. We have a Wireless Linksys router. Comcast cable internet is connected to the router. The router is located under one of our desks on the floor. There are 4 computers that are hooked up to it directly. A lot of our laptops have wireless connections that are connected to the internet. In the back where I do the installs, I utilize a lot of the Linksys Wireless USB Adapters to get online. However lately the network has been incredibly slow. What can I do to determine what computer is the culprit of the slow internet?
