Slow, Network Timeouts, etc. on cable connection

Hi Y'all... My little laptop is slow and having connectivity problems on a cable network. Logging in is slow, and I often get the messages "network timeout" and "cannot find..." I run both Mozilla (mostly) and MIEx (only when I get very frustrated). I get the feeling that the computer is confused and turns the internet connection on and off. Sometimes I get email messages returned that I didn't know I sent... to strange addresses I can't decipher or recognize(!)
Thanks for any help...
