Please Help - Very Low Upload Speed and Slower Download Speeds Also

For the past few days, have had non exsistant upload speeds and varying download speeds, can't get any work done! Have done all the usual checks etc, am thinking its a line issue, connection details below, I noticed the low modulation on one of the upload channels (16 instead of 64):

Re: Please Help - Very Low Upload Speed and Slower Download Speeds Also

Not looking good - only 3 up channels - should be 4 and the qam has dropped - and there are far too many T3 errors.

Try this...
______________

First switch the Hub off for 5 minutes AND unplug it from the mains. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box. Then switch it on again and leave 5 minutes

Then post up the missing downstream data - i.e. the table with the RS error counts and also the up channel data again

Also, in the meantime... If you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.

Not surprised with that connection. It will need a tech visit. It may be a day or so before a VM person gets here - so it may be worth calling it in as it might be quicker - call 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 worth a shot now?

Thanks. 

Is it more likely to be something to do with the cabinet on the road? As nothing has changed my end, just suddenly stopped, unless the router has messed up somehow?
