I've had d-link and linksys standard consumer grade routers, but they tend to work for a year or so then become flakey and require more and more frequent router reboots, I'm looking for something that'll work reliably 'for ever'... should I be looking at business class? or "enterprise grade" or ... what's the lingo for "give me something reliable even if i have to pay 150 instead of 30" in router land?
