Hi,
I have left the "Whole Home WiFi" on, I have never tried to turn it off. The WiFi channel that it picks is counter- intuitive. It started on the most crowded channel in my area, channel 11. 2 days later it went to the channel 1, also fairly crowded. Then it went to channel 6, which is (by far, and consistently so) the least congested channel (1 network right now) . I thought maybe it had figured things out, but this morning, it's back on channel 11, sharing it with 6 networks.
You might think that this is academic. However, we are noticing that the internet drops out for 3-5minutes at a time daily. Last one was 7:56AM today (Tuesday Feb 14). It happens on all computers/phones at once; not sure about the TV yet. It appears that the WiFi connection is still there, but without internet, so it may have nothing to do with the WiFi channel changing every day. So, today, I will set up a computer connected directly to the router by ethernet (no WiFi) and will have it ping the outside world every 30 seconds and see if the pings stop when we experience an internet outage. If it keeps working during our internet problems, then the problem is the WiFi, and I will try turning off the "whole home WiFi" optimization to see if that helps.
Any other suggestions?
Cheers,
...GR
