Re: After years of 63Mbs speed dropped overnight to 50Mbs. Can anything be done?

I don't think I've actually still got a filter, might try a phone cord, would that work?

Very odd that the test socket yields lower speeds!

You are syncing at 59M but the error and snrm figures are not accurate (a known bug with the gui formware). You need to telnet into the modem and then at the prompt enter

ATP>sh
# xdslcmd info --show

 

to get the true figures.

Re: After years of 63Mbs speed dropped overnight to 50Mbs. Can anything be done?

DLM now appears to have banded your line at 55M due to the line instability but your max rate is only 58.7M with an SNRM of 7.5dB, so not much room for improvement. You are just below the minimum rate of Range A for your line , but you might have difficulty getting an engineer visit. To be perfectly honest, I can't see that you would notice any difference between 63M and 55M under normal usage. Even if you were to return to your previous speed, I'm not sure the extra cost of Infinity2 is worth it, you might as well opt for Infinity1 and save a bit of money.

 

If you want to monitor your connection over a period of time to see what is happening in terms of errors etc, have a look  here

Re: After years of 63Mbs speed dropped overnight to 50Mbs. Can anything be done?

Thank you for your comments. It appears that although for years I had been getting the estimated speed for my line of 63Mbs Openreach will not do anything to return those speeds.

 

Once VM have replaced the service do I need to inform BT or do I just stop all payments?

You should give BT 30 days notice. You may as well as you'll be charged for it anyway.
