WRT3200acm: "adapter does not exist"

I own a WRT3200acm, and cannot make wifi work on this device with LEDE 17.01...

From stock configuration, I just activate both radios at /etc/config/wireless and reboot, but I cannot see any LEDE access point; according to the logs, both radios are being detected:

Then, these lines repeat over and over again...

The 3200ACM has known problems (crashes, bad performance) with the current wifi driver / firmware, see

It is being worked by Marvell and a new driver / firmware might be released at the end of the month. No idea how long it will take to arrive in LEDE snapshots /stable.

I've read posts that wifi is (more?) stable with current LEDE snapshots using kernel 4.9 or newer. I am testing this myself right now. But it can sometimes take a couple of hours / days for the problems to show up.

Yes, I had read about the instability and performance issues; but mine had stopped working completely, I could not even see the SSID, even after hard-rebooting the device, and I was fearing something different was happening here. Anyway, it seems to be working again today, at least I can see the default SSID; let's see how long it lasts... Many thanks for the info, I will be following that discussion!

I am using the build below on my wrt3200, I am having no issues.

Another thing to check:

Enabling the wireless LEDs (wifi on, wifi activity, ..) also used to break / crash wifi. No idea if that is still the case. But if you enabled the triggers it might be best to disable them again for now.

Well, I detected wifi stopped working when I enabled the LEDs... so that makes lots of sense; many thanks!

@mojolacerator: While I appreciate your intentions, I think it would be more useful to everybody if you posted a link to the source where you obtained that file, instead of a dropbox folder with the binaries.

click the word "stable".
