Modem resetting problems again

[Welshchris]

Last weekend i had the same problem but seemed to correct itself, the problem is every few hrs my modem resets. the ready light goes out and the sync light flashes and it disconnects for about 45 secs. Anyone have any ideas from whats below?

Here is the modem error log and power levels..

Looks like you need to call up Tech Support and speak to them about this issue, which model is your modem.

[Welshchris]

its the 255

[Peter_]

Definitely sounds like an issue with your connection as the modem is quite new and should be fine, I would give them a ring tomorrow or try the newsgroups.

[Welshchris]

they reckon its a power fluctuation, but as i said to them if this is the case why does it only happen on weekends?

A power fluctuation where on the modem or on the uBR, and what have they said is going to happen with regards a fix for you.

[Welshchris]

they said they will send out an engineer, they said they cannot find a fault on UBR or Modem and couldnt be a power fluctuation they didnt say where tho.

They offered me an engineer but i said its wasting my time to come out when its only happening weekends.

That points towards it being high utilisation on your uBR at the weekend and they can check that if you ring tomorrow and ask them as they have records.

Happened AGAIN! roughtly same time as last nite!

Here is what tech support came back with this morning....

I have a plausible explanation for these occurrences. Whilst viewing the
graphs displaying online device count vs time one can see that these events
occur at roughly the same time in the early morning. One can also see that a
chunk of around 30 modems will go offline from the most utilised upstream
channel and come online on the least utilised channel. Due to the uniform
nature of this and the repeated nature of it in geographically separate
areas, I believe it to be the action of automatic load balancing which is
active on most (if not all) UBRs.

Sounds like something from 2nd line support as 1st line would not such access.
