In theory you are right. Today I wached Internet TV with the AVM plugs, no big resolution, more sd than hd and I had so many dropouts, incredible. Never had such a bad performance via wifi,
I did now a test with my current 2,4GHz wifi:
iperf3 -c 192.168.178.100 -fm
Connecting to host 192.168.178.100, port 5201

Wow, now in the evening it is so much better than in the afternoon. My feeling says I must try the 5GHz-band, although I wonder why other networks influence my wifi so much. This is a family house and neighbours are 100-300ft away. The old house is built of big stones from a mountain (not concrete) and bricks and I have problems with the signal within the house.
I noticed in the afternoon with the AVM plugs, that the transfer stopped for a while and that was the reason why I changed the cable. It looks like I had the same problem with the 2nd cable too, when I watched internet tv.
So I fear I have to find a wifi solution.
What I need in any case, is a device, which allows me to use a tv and dvb-box with wifi. TV and dvb-box have ethernet only. And the question then is, fi this device shouldn't be capable to do more.
I have an AVM Fritzbox, which is connected to the internet and from this Fritzbox 3 ethernet Cat6-cables are going to the cellar, the ground floor and the 1st floor. The tv, which should use the wifi-bridge is in the 1st floor. A router is a floor below of the tv (same room location), so I think I can save a router in the 1st floor and use the rooter below for the tv. And then we are again at this discussion. I need something to make the tv, a.so. wifi capable and connect to the router below. As already discussed for this situation I do not need wds, but it would be nice to have 1 ssid for about 10 mobile phones. At the moment I have 2-3 SSID which have to be changed at the mobile phones from time to time. In theory this should work automatically with an app, but it doesn't. The 10 phones can be registered at the same time, but are not used at the same time. Normally max 3 phones are used at the same time. Same with TVs. There are 4 TVs, 3dvb-boxes, and other devices, but normally they are not used at the same time.
