I have a cable modem used with a LinkSys Router (1 Port) and a Micronet Etherfast 5 ports mini hub 10mb tp8. I have 3 computers that share the internet and network here at home. The network speed is excellent except the internet at times seems to be super slow on the host computer. However, when a site is accessed on the host computer, the client computer internet sharing seems to be fine. Any ideas as to what the problem might be? I also run McAfee VirusScan Professional Edition v7.00.5000. Firewall is set to allow all traffic.
