For months my internet connection keeps dropping, the wifi signal is strong but the underlying connection keeps dropping. This is particularly obvious during teams calls where the wifi is connected but the calls drops.
Here is my router status for analysis, thanks for any help.
FYI I used to have TV and internet, I now only have internet but any SNR have not been rebalanced.

Your down power levels are all high - albeit still just in range (-6 to +10 dBmV) There are too many T3's as well - call it in as a fault and see what they say when they check your connection.
Also, If you haven’t already, set up a free, secure and “offlsite” - “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”. Click the lower link (Share Live Graph) then, click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

Hi @anthonymc11,
Thank you for your posts and welcome back to our community forums. We're here to help.
I'm very sorry to hear of your recent connection issues. I've just checked over things on our systems and I'm unable to detect any faults currently. Have things improved at all since your posts, or are the issues still present?
Thanks,

Yes the issue persists . I was advised by support to change the power supply which had no effect. I now have an engineer booked

Thanks for coming back to us anthonymc11, glad to hear that you have an engineer visit booked in. If you get the chance, please let us know how the visit goes 👍
