I upgraded my cAP ac to ROS 7.13 and my radios disappeared. The device doesn’t even show them as hardware. Luckily, a downgrade to ROS 7.12.1 worked and I got my radios back.
What have I missed or done wrong?
As always, help appreciated.

ROS 7.13 has unbundled wireless drivers. At the same time ROS 7.13 is a bit too big to comfortably fit on 16MB flash on arm devices. So what probably happens is that wireless drivers package fails to install.
Just this morning (remotely, 75km away) changed a cAP AC towards qcom-ac driver.
Went just fine and users were connecting immediately again after install.
You need to make sure to remove wireless package. Reboot and check it’s gone.
Then you can install qcom-ac. Reboot again.
First make an export of your wireless settings part, so it’s a bit easier to set everything back up (has to be done manually since the complete menu structure is different).
Adding to what mkx indicated:
also check your Files section if there are no unnecessary files there taking up space.
I had, recalling from memory because I did check that part, about 1.7Mb free when wireless was gone (already on 7.13 at that point).
Worst case, you have to netinstall that device to make sure it’s completely clean (which can be an issue when it is remote).

Remind me - is there a way to reboot a device into netinstall mode from the CLI/Winbox? I’ve always used the button on the device itself.
Power on, press the button and keep it pressed until it appears in netinstall window (or command line when using Linux).
From CLI type
system routerboard settings set boot-device=try-ethernet-once-then-nand
then reboot.
Thanks - that’s handy to know for cAP ac devices which are already installed on a high ceiling. They’re PoE so can cycle the power if it doesn’t work.
Thank you all for the replies. After I posted, I looked again at the changelog for v 7.13. The legacy drivers for older devices are in the extras package. I added the wireless package from there, rebooted and everything is back to normal. I’ll look at the other packages installed and see what I don’t need.
This forum is the best - users are helpful and friendly. Thanks!
