BB excruciatingly slow after clearance of exchange fault.

[Amunre]

Following a combined network outage and equipment fault at local exchange, an Openreach techie visited and restored service (phone service was OK throughout). However since clearance of fault, speed as been very very slow, so much so that web pages with extensive graphics including BT.com have timed out. Is this sort of thing normal? I am led to believe that my speed would return to normal after a couple of days. Is this so?

Due to a long rural line I don't have very fast speeds in normal times.

Thanks for any advice

can you post stats from your router and also run btspeedtester and when first test completes then run diagnostic test and post results

Thanks for quick response.

Have BT Business Hub 3 (not 4) and unsure of how to get stats.

Have run BTW speed test results as follows:

Test 1

Download 0.24

Upload 0.33

Ping latency 64.50

Test 2

Download 0.24

Upload 0.33

Ping latency 50.88

Diagnostic check failed

The Performance Tester is currently unable to run a speed test for your broadband connection. Please try again shortly, however if this problem persists, raise the issue with your service provider.

Have used different browsers throughout this sorry saga and only very marginal improvement using Chrome over Microsoft Edge. (Windows 10)

all the problems at the exchnage have resulted in your noise margin increasing to 17db causing a reduction in your conenction speed.  if you can maintain connection and with 3 days conenction time if noise margin has not started to reduce back to normal 6db rpost the stats and we can see if mods can help get noise margin down and speed up

Thanks, will keep an eye on things for next couple of days and repost if necessary.

Re previous message.

No real improvement in speed as yet.

Current results are:

As you can see, Noise Margin is down only slightly. Should I give it a day or so longer before further action needed?

Hi Amrune,

The attenuation shows you're on a very long line which can take longer to recover. Try leaving it for a few more days and let us know how you get on.

Cheers
