The bookworm wifi saga continues. After a software update that

After connecting a usb-wifi dongle and rebooting, first the usb-wifi
interface came up unprompted and then the internal wifi came up a
moment later. Now both interfaces are up and working using 2417 MHz
channel 2 but different IPs.
 
So, it looks like the behavior of the internal wifi is dependent
on both wired ethernet and USB ethernet connectivity.

 
It should not be, but I'm confused you mention USB-WiFi in one paragraph
and USB-Ethernet in another.

 

Apolgies for the mixup. I meant to report that the behavior of
the internal wifi seems to be affected by both use of wired ethernet
and use of usb wifi. The internal wifi connected spontaneously after
connecting either a wired ethernet cable or a usb-wifi dongle. Alas,
that behavior is not repeatable. In the present config the usb-wifi
dongle connects, I can't get the internal wifi to connect though
it does detect the access point.

There does seem to be a large discrepancy between wlan0 and wlan1
signal strength: wlan1 reports 93-96%, internal wlan0 only 79%.
Prior to the recent upgrades (but still bookworm) wlan0 reporting
more than about 70% gave a decent connection.

Did you start with a fresh Bookworm image?

Initialy, yes. It was customized on microSD,
moved to a USB hard disk using Raspberry Pi Imager.

What have you installed since?

Nothing apart from supplied upgrades, but I am using wayland, which
has been described as troublesome.

What other hardware is connected?

One powered hub, running the added usb-wifi dongle
(old Ralink RT5370) plus an old Dell keyboard and mouse..

Are you using an official power supply?

No, but the Pi5 reads 5.07 volts at the GPIO header.

As this saga plays out the USB-Wifi dongle seems to
work quite well. Maybe it's all down to the better
signal strength. Because the problem appeared shortly
after an OS upgrade I tended to blame that. Perhaps
I'm mistaken.
