I do a lot of P2P and assorted traffic. The router and modem die on a regular basis and it's really annoying. I have a linksys WRT54G v5 router and a Terayon TJ715 modem. It could be the cabling to my house, but I the connection is very unstable when doing P2P type activity. I'm prepared to spend upwards of 700 dollars to get this fixed... but don't want to spend more then I need to. What do you recommend.
