Just recently my wifi has become terribly slow. I have a Google Nest Pro point connected to a fiber router, and three older Nest points.
I reset the network completely, but Google Home shows one of the Nest Wifi points off line and two with good connections. Periodically they show as having low connection.
I hooked up a wifi scanning program on my Mac, and what I see leaves me deeply confused: it lists only three APs --
1. The main router
2. Two on the second floor
It does not show the point on the first floor at all -- even though this is one of the ones that Google Home claims has a good connection.
Another thing that has me confused is that the 802.11b/g/n APs all show as having what seems like quite high noise ratings: all three are about 45%. One's on channel 11 and two on channel 6.
802.11ac shows low noise.
This makes me suspect that there's something jamming my 802.11b/g/n connections, but I don't know what this could be.
One kind of wild guess: we just got our gas and electric meters replaced. I see something in the scan on channel 6 with no SSID, but no idea how to track this down, or what to do if I do. This is just a guess, based on this coming on line at about the same time as my network started to slow badly. But it could easily be something else.
Any suggestions for troubleshooting this?
I understand that the Google Wifi APs choose their own channels, so I couldn't try switching to a different one.
