hey all, i know there is the sticky thread for routers, but i was wondering about modem/router combo units. my parents are switching to comcast soon and want to avoid the rental fee ($8/mo) for the modem/router. i looked at the comcast site and saw on their supported list that they have the Motorola SBG6580, and Netgear N300/N450/N600 listed as retail-available combo units, but was wondering your input on them. I would rather get them a single unit for ease of use, but have also heard that they are not as reliable as separate modem and router. what are your thoughts? also would like to spend as little as possible since they will only be getting 25mbps internet anyway and dont need super high-end stuff. i just dont know anything about networking hardware so i was hoping someone could help me out. thanks!
