Since setting up my new Pi5 some oddities have emerged with
the WiFi, includidng seemingly slow/erratic ping times despite
a near 100% link quality as measured with wavemon. The icon
in the top menu bar didn't light up all the way, suggesting
some disagreement between wavemon and the OS . At one point
wavemon reported that rfkill had prevemted wifi startup, though
rfkill reported both wifi and bluetooth unblocked. There was
one report online of a bookworm bug along this line, does it
aply to RasPiOS?
Between the two, I'm rather confused. Over the past year or
two wifi has gotten worse,I thought because of interference
from neighbors, who now number close to 20. But, during a scan
wavemon consistently reports my access point as the strongest
signal. Is "strongest signal" not sufficient by itself?

Check the channels they are using - then choose something else

Don't wifi connections change which channels they use frequently? Unless
you control all the nearby routers, I don't think it would help a ton..

Good routers monitor nearby signals, and will change channel to avoid conflicts. With some you can override this
Good routers monitor nearby signals, and will change channel to avoid conflicts. With some you can override this
.4GHz tricker as it is pretty saturated every where outside the back of beyond, but the rule is to stick to the non overlapping 20MHz wide
channels at 1,6 and 11. Any use of the other channels will cause far
worse interference, so steer clear of that.
To pick the best one of the three, check the signal strength of
competing networks, not at the router, but where your clients are
located as that makes more of a difference. Use the channel with the
weakest competing signals. On Linux iwconfig will show the signal
strength and link quality of the connected access point, and iwlist scan
will display information on all the access points it can see.
Foe at least android phones there is a free app called wifi analyser or something which shows/lists channel spectrums on at least 2.4GHz.

No. They dont. You assign a (centre) channel to a wifi station. I t

A great app, I've used it a lot.
Unfortunately a recent Android update has throttled the amount of
scanning an app can do, so if you try to leave it running and wander
around the house to measure signal strength, you find it stops after a
few seconds and needs restarting. It's not just that app, but the alternatives too.

You can turn scan throttling off, by going into developer mode. <https://www.wifianalyzer.info/?s=wi-fi-throttling> I just tested it
on android 14. It said it worked in Wifi Analyzer.>> I'm not sure how
much it improved scanning.

Automatic channel setting with the option to overrule. Mine has it, I've switched it off as it forces connected devices to also
dynamically switch channels. So: Pick the "cleanest" channel at your router and make it fixed. Do the same for possible
accesspoint (best is "the same" channel to allow seamless takeover).

My router has an 'auto' setting for channel. Is that it? Why would
anyine use it?

speed, limit bandwidth (adjacent channel usage). And on 5GHz, avoid channels in the radar band.

WIFI points all with different SSIDS...spread fairly evenly over the spectrum...
I cant see NHS staff doing any setup and contractors probly send in a PFY.
