Iv just reread his post if the disconections are only for seconds

I would say its something to do with your network not the modem as when a modem drops conection due to a fault

It would tqake longer that a couple of seconds for the modem to relock

it has to re lock down stream then upstream and regrab the con fig before going back on line

as i said above next time its doing it look in modem config page watch modem lights

and ill bet that it operational and it your network

if it is the modem you will see it droping out
posible cause if its signal related is a faulty drop amp on the blink in the cab week signal droping more at peek time when every one is online

if it just slowing down for a few secs and not disconecting posible/likely that you ubr is a bit more over subscribed that usual nad need resegmenting

with out more information of what the modems doing when you experience this no one can really sergest where the problem lies.

if you go in the modem web page and post the log it will give more of a clue to whats going on with modem
