Reading thru this post i am a little confused. You said netgear then belkin? Wondering which one you are using. Also if you are wired to the router you should get 100mb speed from computer to router, then get speed that you pay for from dsl modem... Also linksys are sold without wep enabled, this is something you have to log in and set yourself.
Possible causes of slow speed:
Bad Router
Bad settings in said router
Bad ethernet cord
using a crossover cable when should be straight thru
conflicting ip address in your modem and router<<<>>>not sure on this one because i believe you would not get internet access with conflicting ips. I know Belkin comes preset to 192.168.2.1 and i also know that some ISP send out modems that are set to the same ip.
Anyway just trying to help
