I've had a Motorola SB6141 modem running happily for months now when all of a sudden my connection ground to a halt, a speed test indicated that the download speed was fine (still approx 50mbps) but the upload test doesn't even start (hangs) or crawls at 0.1 mpbs at best. It's usually around 10Mpbs.
I unplugged the modem the night before last and left it unplugged all day, I reconnected it last night and things seemed normal (did speedtest) then after about an hour the connection ground to a halt, sure enough no upload bandwidth.
Tried all the usual steps, cold boots, reconnect all coax, direct connect to modem, bypassing router, reprovisioning of modem. Not sure what to try next, it seems like download speeds are just fine but for some reason the upload is basically crippled.
AFAIKT the modem status looks OK: http://img823.imageshack.us/img823/6589/b3jy.png
