Internet Keeps Dropping Out Every Hour
 
Hi,

For the last 3 days I have had hourly disconnects from Virgin Cable. I've been with Virgin for 4 years and bar the odd major outage have never had such instability.

Can anyone advise on the stats below SNR etc etc.


Thanks,

Magma82

Can't help, but thought I would also voice my frustration at Virgin Broadband. The last couple of weeks have been terrible.

Downstream power level is too low, do you have an attenuator on the back of it? Your upstream is really good which would suggest a forward path attenuator may be on your line.

Re: Internet Keeps Dropping Out Every Hour
 
If the is no attenuator then you will need to call in to get an engineer booked.

Hi All,

I have no attenuators on the modem or from the brown box outside. When it was first installed 4 years ago, the engineer did put a 6db attenuator on the back of the modem. I removed it as it was affecting the signal.


It is just cable F connector joiner in the brown box outside upto my bedroom location.


:( looks like an engineer visit then.....

Re: Internet Keeps Dropping Out Every Hour
 
Your upstream power level may look OK but the modulation is QPSK rather than QAM, as you are having problems this is indicative of a line problem and needs investigating further.

You need to ring it in.

I think I may be suffering from the same thing.

@ The OP , you wouldn't be in NN8 or NN10?

I've phoned in twice to India about almost continual drop outs over the last 4 days and while my 1st call resulted in the promise of an engineers visit at the last minute I got a phone call telling me it was cancelled along with a promise of £2 off the next bill. :rolleyes: Todays lengthy conversation with Kumal ended with the promise of the mythical callback after he tries to find out whether the issue in NN8 is affecting NN10. :) After an hour or so on the phone I had almost lost the will to live so didn't argue. :(

Thank goodness for my backup Be conn. VM are fine when it works but when it breaks they are useless. I'll see if if it gets fixed tomorrow otherwise I'll be calling the "Thinking of leaving" option. Off shored TS, while friendly and polite are completely useless at reporting a fault or getting an engineer out. :mad:

Have you tried the link in my signature as it should work on a BE connection I think.

As Masque has said in other posts if you ring the "Thinking of leaving us" option does not mean an instant solution however you will (or should) be put through to onshore support in Liverpool with both first and second line support available.

Proper diagnostics will be conducted on the line and if an engineer visit is called for then it will be booked.

Hi All,

I have just redone all my F connectors to the modem and now have the below SNR stats.


Are these any better????

Your still on QPSK not QAM!!!!

Hi PIP,

sorted it, I power cycled the modem and now get QAM.

See Stats below :) is that all ok now????

Thanks Masque, I already found my way there and it says there are no issues in my area.

Thats all I want, why is it so hard to get satisfaction from VM. My Be connection went down, I phoned support and a faulty modem was diagnosed. Be got a replacement to me the next day by courier. I installed and was back on line straight away.
