Ok, as the topic suggests, I currently have a 4 port wireless Belkin router and also a 5 port hub. The setup is like this, Cable Modem --rj45--> Belkin Router --rj45--> 5 port hub. There is usually one laptop using the wireless connection while most of the computers are connected to the hub via rj45. Our setup is like this because the modem/router is upstairs and then the hub is in the basement where most of our computers are. So the problem is when we're using the router, it lags like hell. I did a test, I connected the hub directly to the cable modem. The expected and normal pings (10-30) came back. I was wondering if we might have a virus over the wireless network, or if someone might be leeching off of our wireless service. Basically, I wanted to know if I could get the instructions to listing all the IP's/users connected to the router, especially wireless connections. Secondly, I learned somewhere to clean a network I'd have to connect each infected PC separately to the modem and clean that system of infections, and then connect each clean systems back onto the network. Is that right? Much help is appreciated, thanks!
