I don’t know if this belongs in this forum and/or if I am just looking totally ignorant by even bringing it up but…
Recently I brought in a second wifi router to offload and isolate my HA and media server traffic. For weeks I was pulling my hair out trying to isolate where and what was causing the random packet drops and general slowness of this new subnet (running about 1/3 the speed of the other subnet/router).
It was finally solved and I am smiling big now with the simple toggling of the router switch from dual 20/40Mhz wifi to just 20Mhz wifi. I have found no devices so far that will don’t communicate, and very well thank you… using this setting.
I just thought I’d toss this out in case anyone else is having weird wifi.
