It's a router brand, not an actual router. About 1/3 of their entire line are utter crap. The same applies to LinkSys, Netgear and the premium looking Belkin. There are about 4 other brands I've seen, but their statistics are a lil worse with around half of their routers being utter crap.
As I said, it's hard to recommend a router because of the widespread phail that litters the industry. Find a router that you think sounds good, search on every shopping/review site to find out what the reviews say, then decide if it's popular enough for you to risk a year of regular dropouts and router crashes and nights of frustration and wasted money on. If you don't do your research, that's what lies ahead for you, with a 80% chance of me being right.
That said, it could be your ISP that causes line dropouts etc. Lots of ISPs suck. I can't offer any advice about that at all though.
