Intermittent broadband connection

Hi, 

Since upgrading our broadband network to 500 around end of Nov, every day we have had issues with the connection. Every night around midnight it seems to cut off for at least an hour and then throughout the day on a lot of days we get intermittent issues. 

 

Please help! It's getting frustrating when trying to work from home

Re: Intermittent broadband connection

Is that happening on bothe wifi connections and ethernet cable connections at the same time?
Stats look ok although the qam has dropped on 2 of the Up channels.

So to visualise network connection issues do this.
_________________________________________

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.

Re: Intermittent broadband connection

BQM looks poor. You need VM to look at your connection in more detail and advise.

Call it in on 150 (VM Phone) or 0345 454 1111 (any other phone) and see what they say when they test the connection. 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

Re: Intermittent broadband connection

Called but got put through to an automated service which tested my net saying I have intermittent issues. They have sent me a link to use to book an engineer after I monitor net for 24 hours
