Slow upload speed, North London

Hi 

I noticed a few days ago my e-mails were taking forever to send, especially with attachments. Not to mention we use a Remote Desktop Server for most of our work and that rely's heavily on connection speed... Which has meant work has been painfully slow for me.

After many speed tests, I can see my upload rate has been significantly slow. Between 0 and 1 Mbps. Download speed is fine, no issues there, I get 55 to 60 Mbps.

I am on a wired connection and I have also tried wireless, both give the same result. I am based in Haringey, North London and the VM area service status says there is no problem. 

Can someone at VM help me with this?

I suspect the slow upload rate is affecting other areas of the house that rely on internet. I have since unplugged all of these to see if it was affecting it... No changes... Ah the joys of a "smart home"...

Re: Slow upload speed, North London

Your connection is not good. All of the down channels are at too high power - recommended max is +10dBmV. And 3 up channels have dropped to 16qam. You need someone from VM to look at it - but it will need a Tech visit to balance the signal.

Call it in on 150 (VM Phone - free) or 0345 454 1111 (any other phone - national rate). Calling at 08.00 midweek (09.00 Sun) is the best time to get through quickly. Although some people are still reporting getting through fine at other times with no long waits so worth trying now

If you get cut off after an automated reboot cycle, just call back in a couple of minutes as the system should know that you have just been on and it hasn’t helped and put you in the queue.

Or try options 1,1,4,4, “thinking of leaving” - they usually pick those calls up quickly and then transfer you to the appropriate queue (or cut you off !).

A VM person should pick this up here and respond, but it can take a few days for them to get here.
