I had 2 different 802.11g Belkin routers several years ago that both had connection dropout issues that no firmware upgrade could seem to fix. And today I was at a friends house whose Internet was mysteriously down.
He has a Belkin 802.11n router that seems to drop it's WAN about once per day. He ended up just buying a replacement as firmware was not a solution either.
I guess Belkin should stick to simple stuff like plugs and wires.
