TL-WPA8630P KIT suddenly really slow
I use a TL-WPA8630P KIT to extend my network to the addict. I noticed the internet was getting really slow the last days. I did a speedtest and it doesn't reach over 1mbps, the normal internet speed should be 100mbps. I moved the extender to the same room, but this gives me the same result. I tested on wifi and on a cable, it doesn't make a difference.
See result from tpPLC utility.
Speedtest on the router:
Speedtest on the powerline:
Any clue why it's so slow? It has been working fine for several months.
Thanks & regards,
