@ir11 To be fair I have to mention, that after some changes the performance of my Deco mesh system is OK now; I upgraded my PiHole hardware my internet provider got better recently

@TP-Link Hi and thanks for your reply. The Archer is in another location, so in no relation to the Deco network. I notice bigger performance drops after couple weeks online, system reboot mostly...

@arnie2019 Same problems on my Deco M4R. CPU low as 4% for about 5s then skipping to 97% for another 5s and so on resulting (?) in bad performance (www loading). I am not happy with performance...
