In the meantime see if there are any ongoing works that might cause this.
Check for any “known network faults” ... on...
1) Try the “check service,”Area status webpage" (link at top right of this forum)
2) Then also try the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. and tells you of more local issues down to street cab/ postcode level.
Then to keep a record do this... _________________________
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
I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired 2 WiFi,) SH2 in modem mode with Airport Extreme Router +2 Airport Express's. On VIVID200, Talk Anytime Phone, x2 Mobile SIM only iPhones.
Sorry to hear you're having intermittent issues that occurs at night. I haven't seen any reasons for these issues at our side and everything looks in specification currently.
Are you able to create a Broadband quality monitor as suggested by jbrennand. If you fully reboot your router and let the data collect then post your live graph to the thread so we can see what happens at night at the router. With this information we'll be able to investigate further.
