Hi my router and/or wifi is dropping out several times daily my router logs are attached, T3 timeout seems to be the culprit. My service check returned no issues found

I can see via diagnostics my end that your main power levels from VM to the hub are all within specification. Looking at your devices currently connected to the hub, again no real concerns, a few are sitting on 2.4Ghz instead of 5 Ghz but again no real concerns.

As you said and looking at your activity logs, T3 timeouts are way too high. This could be a number of things from damaged cables to wear and tear on the splitters or connectors internal or external.

I think you would benefit from having an engineer visit to give your setup a full once over.

Do you want me to try and get an engineer over?

Hello.   I have been having significant issues with disconnections (up to 15 in a day).  I have had numerous engineer visits, cable changed and spent hours on the telephone and 8 weeks later no solution.   My neighbour (also VM customer) is not experiencing the disconnections.   Another resident in the street is experiencing the same problem as we are.   VM cannot seem to resolve this problem.  Any ideas?   Thank you.  Chris
