Hi, I have some doubts about of using some powerline kits.
I've been using a TpLink 4220 kit and I have to admit that they are very reliable and I never have connection drops and the speed reaches about 60Mb/s on ethernet output from the receiver. I'd like to renew my devices and to use a more performant kit as I have a faster internet connection since this earlier month (almost 200Mb/s).
I've tried a TpLink 8630 kit and I noticed a faster bandwidth up to 100Mb/s on ethernet output from the receiver but after some minutes my network's internet connection fails and I have to restart my router. I've tried many times excluding adapters, etc. but I always get the same results.
I've also tried a Fritz 1260/1220 adapters kit as I'm using a Fritzbox 7530 router to set a Mesh network but I get the same results of latter TpLink powerline but I can't reach 70 Mb/s even as peak speed and the network's internet connection fails and I have to restart the router.
Why do you think I have these outcomes?
