Hi, I saw another post with the same title / problem, but no luck to understand the solution.

I have random internet cuts and I have been investigating a lot where the problem could be.

I have the UPC router configured as modem -> My own router which I use for everything

Any suggestions?

localhost7 The T3 error messages can be ignored. Also, the signal quality of your connection is optimal.

We ask you to restart your modem and then your router and test it again. If the error is still present, we ask you to set your modem in router mode and observe it for a few days regarding the interruptions.

Greetings

After restarting both routers, today again had a couple of interruptions. It is never noticeable, but probably there is a micro cut in connection from time to time, which is enough to cut a conversation on the phone or Teams on the PC.

I have now setup the UPC router to router mode, not modem. Will wait a few more days and see if it makes any difference.

Ok, yesterday had another two cuts.

UPC device is set on router mode. Don’t know how to debug further.

I switched UPC router to modem mode again. Clearly the mode was not causing the issue.

I made some changes in my router (Archer C80), like deactivate EasyMesh, increase beacon interval, increase Address Lease Time to the maximum 2880 minutes, deactivate UPnP, remove address reservation for some devices (only keep it for NAS and Home Assistant), etc. Will keep you posted if I get new internet drops.
