Alright the internet works blazing fast 4.4 mbps then a few hours later it starts slowing down really bad or stops completely then i unplug the modem cords and reconnect them and it works blazingly fast again. I have 3 comps hooked up to hub with road runner cable. Im wondering what could be causing this, is it road runner or is the hub going bad we have had it for about 5 years?
