Last weekend I've run update-all script and since then my wi-fi will sporadically connect to internet. Never had this problem before. Did something in updates affect driver? I was able to reconnect twice since then, but could not figure out what triggered wi-fi to start working again.

Any idea what might cause this issue?

Thanks!

I also had problems with wi-fi on one of my MiSTer's after an update and never figured it out. I finally gave up and used an Ethernet cable so I could do what I wanted to do, then disconnected it again. I am thinking about starting over from scratch and copying what I need back to it.

More clues are needed...

You don't specify which chipset your USB WiFi adapter uses.

There are many WiFi drivers statically built into the kernel.

If you don't know your chipset one can usually figure it out by googling vendor and product IDs for the device.

If you go into the F9 console (login:root passwd:1) and type "dmesg | more" you can get those IDs as well as note any errors that may be occurring when the WiFi adapters driver is being loaded - or if its being loaded at all. Try and unplug and plug it in and then run dmesg...

Also, and its a longshot, but It may help to verify the "country=" is correct in wpa_supplicant.conf.

I just updated to OS230423 and my Wifi is broken as well. Using recommended Edimax dongle, and it worked perfectly fine before the update.

Yes, the 2023.04.23 update broke some (or all?) of the Edimax adapters.

(Note that this thread is an old revived thread and was probably talking about something else)

Filed a ticket here for anyone that can add any detail on model number or wants to follow along:

Thread specific to today’s update:

please try to apply patch from

Same here with this two of these:

Tried patch and didn't resolve. Oddly plugging in ethernet cable wakes up the broken wifi and connects until next reboot.
I think it did that before patch as well.

When broken for me wifi script would run, see wifi, enter PW, and then fail saving.

Plugged in one of these and both setups connect to wifi without issue:

Not sure if related, but my bt+wifi combo adapter (bought the same one you listed on amazon) wasn't stable until I double checked my /media/fat/linux/wpa_supplicant.conf had all fields populated correctly (country field for example). Sometimes it would work, sometimes it wouldn't. Can copy /media/fat/linux/_wpa_supplicant.conf to /media/fat/linux/wpa_supplicant.conf and update fields according to your wifi settings.

/media/fat/linux/wpa_supplicant.conf

ctrl_interface=/run/wpa_supplicant
update_config=1
country=US

network={
ssid="WifiRouter"
psk="wifiRouterpassword"
}

I'm having the same issue and have narrowed it down to WAIT_FOR_SERVER="true" being turned on in cifs_mount.sh. I haven't figured out why it's causing it but turning off the auto mount makes the Wifi work every time.
