Hi,

had 50mbit now since November 09, up until 5th Jan 2010 this was pretty fine, no real issues so to speak, only fault i really found was downloading @ max speed sometimes the modem lost connection and died, so just limited the speed to about 95% and all was fine.

Since the date above if i download anything the modem loses sync, and i have to powercycle it to reconnect, my speeds have been pretty poor aswell, ive had an engineer out 3 times already for power issues, and atm there are 2 yes 2 Forward Path Attenuators stuck on the back of the modem.

To make this clear i have Virgin Phone, Normal Virgin TV, Virgin+ and 50mbit BB. The V+ is in my Den, and the Normal Virgin TV in the front room.

I have been onto Newsgroups throughout this issue, and they have said this is down to a Motorola fault, on my UBR.

I can see by the modem screen i am suffering LOTS of T3 timeouts, and correctable/incorrectable at high amounts.

This can effect me in different ways, sometimes i start a download and instantly bang the modem shuts off and i have to powercyle, or i can go 10 mins then it will drop out, downloading the BFBBC2 Beta took 5 resets to get the 1.5gig file.

The Engineer team have put me under the Fault F001105016, but i can't find any information about this fault, or the status of this.

But if anyone has some ideas or help it would be appreciated, as there a 5 internet users in the house, so it gets pretty annoying when one of them downloads something and the net goes off.

Anyway heres the modem stuff for you guys too look at, see if you can see anything glaring at you.

At my wits end with this, pretty pointless paying for this internet when all it does is crash when i download, or view video streams..

Thanks in advance for any help.
