I have the problem that the repeaters restart several times a week. I have the Speedport Pro with the Telekom repeaters the white rounds. Actually, it's just one of the things that causes constant problems. So the whole thing is like that. Speedport Pro to Repeater 1 Repeater 1 to Repeater 2. Sometimes it goes like this over and over again all day. A reset as well as that the Telekom employee said to me does not bring anything. The LEDs run through all the time and after 5 minutes they all light up and the Internet is back. Online meating is not possible, as is watching TV or Netflix. What could be the problem?
This is because you have more and more losses from repeater to repeater to repeater. That is simply not a good solution.
The Speed Home Wi-Fi (SHW) seem somehow unable to properly import firmware updates via Wi-Fi.
Many users report such problems with the SHW Repeater.
The solution is to first load the updates into the repeaters with a LAN cable (connected to the router) and only then couple things via WLAN.
