Very low upload speeds

Hi,

For the past week my upload speeds have been terrible - about 0.2 mbps at best.  I have tried restarting and resetting the router, and have checked the status of broadband in my area which reports no problems.  I would be very grateful for any help.  My download speeds seem reasonable at 50-60 mbps. 

Many thanks in advance.

Here is my router (Super Hub 2) info:

Re: Very low upload speeds

Three of your four upstream channels are out of spec (The QAM level should be 64).

That and the T3 errors show you have an issue with your line.

Re: Very low upload speeds

Many thanks for the speedy response.

I did another hard reset of the router and the upstream status is now as below.

Is there anything I can do from my end or is it a case of waiting for VM to sort out the line?  I'm a bit perplexed as to why it says there are no issues with broadband in my area when I check, if the line is to blame...

Thank you again.

Re: Very low upload speeds

You shouldn't be getting those T3's. Call it in so VM can check your connection.
