Low download speed M350 Broadband

Hi

I am experiencing slow download speeds of around 35Mbps (tested using wired connection).

I normally get 350Mbps or more. Upload speeds seem as expected. Having read some of the other posts on here, do I have a problem with Channel 24? I am seeing lots of errors on Channel 24.

I have rebooted my hub several times and checked all my cables for a good connection. I have also done a reset on the hub.

No reported problems in my area, status reports OK

Can anyone help?

Thanks.

Re: Low download speed M350 Broadband

Two of your Downstream Power Levels are too low, this is also be reflected with the Pre & Post RS Errors on those two channels.

This will need an engineer to put right.

You can either call in (08:00 is the best time) or wait on here for a few days (6 to 10 days average) until one of the VM Forum Staff comes along.

If you wait on here Do Not bump the thread it will put it further down the VM 'to do list'.

Re: Low download speed M350 Broadband

Thanks.

Channels 23 and 24 seem to have now returned to normal, having been low for 24 hours. No idea why!

Download speed is now up to 200Mbps and climbing.

Re: Low download speed M350 Broadband

OK, I seems to be back to low download speeds again.

Back to low download speeds (around 30Mbps). All cables seem properly connected and secure. Rebooting modem doesn't help.

Will wait for a response from a VM moderator.

Re: Low download speed M350 Broadband

Hey there tetleyboy, thanks for posting on our Forum and sorry to hear about your broadband issues.

 

I've had a sneaky peek at your network details using the information we have on here and can see some downstream power issues on a few channels which will require a tech visit. I've booked on in for the soonest available date and you can find the details on your online account where you may re-arrange it if required.

 

Thanks,

 

Lisa
