i'm going to be changing my ISP on 12/20/03. while earthlink has been fine, i will be able to go to wideopenwest(wowway.com) and get a faster modem AND cable tv connection for only $15 more then i'm paying for the second phone line and the earthlink service. does anyone have advice on how to make this switch as painless as possible? also, should i install a firewall in addition to the norton system works? thanks in advance.
