I always use Belkin router & adapter. Their routers come in a wide price range; my router & adapter have lifetime guarantees, but I do not know if all their wireless products do. I had a router "die" once; I bought a backup one so I would not be off-line while the dead one was sent back to Belkin and a new one sent to me. The replacement router was whatever current model was comparable to the old one. Since then, I keep a new spare router ... just in case. (When I returned the router, they sent me an e-mail with a UPS auth. to pay the shipping.)
