BB speed after power cut

david29dpo

I get 1.1 Meg at best due to being very rural, not bad considering the line length.
However, we get a number of power cuts (about 1 every couple of months) and the speed drops to 0.2 Meg!
I have to ring Plusnet and a few day later the speed goes back to 1.1 Meg.
Is this normal? Is there anything i or plusnet can do?

The line will need to re-synch after each power cut, this can take a few days to attain the optimum speed and should be automatic.

It sounds very much like standard BT Dynamic Line Management dropping the IP profile because during the course of the power cut the router synced low. Plusnet won't have done anything - the DLM will automatically restore the IP profile after a while on the normal sync.

What you could do which may or may not help is switch off your router when there is a cut and only power it on once the supply has been restored.

As it happens we had two power cuts last night (but I'm on cable) and on each occasion just after it was cut there was a brief period of only a few seconds when it came back on only to cut again. If yours does that and the brief on period is enough for your kit to start negotiating a slow sync then there really isn't anything you can do other than put your router on a UPS (a bit overkill imo). The chances are even a cheap one would keep a router going for an hour or more.

An average UPS can keep a computer running for about 20 minutes, drawing an average of about 400w.
Bearing in mind the average router only costs about £8 a year to actually run, a UPS would keep said router on its own going for, well, easily a month I reckon if not longer.

But yes, a UPS purely to power a router is over the top, but may be a prudent investiment for a computer as well if power cuts are a regular occurance in rural areas.

Thanks all, should be back to normal in 24 hours. I have looked at UPS, may be a good idea!
