5GHz WLAN becomes unavailable


#1

Hi everybody,
the last days my Qualcomm Atheros QCA9880 802.11bgnac WLAN interface becomes (randomly?) unavailable. For months everything with the 5Ghz WLAN worked fine and the radio0 WLAN was permanently available. The WLAN shuts down, while 2.4GHz WLAN is still working. I rebooted Omnia and the 5GHz WLAN was available after reboot. Also Disabling/Enabling the radio0 interface with Lucie “solves” the problem. I don’t have any idea whether this might be a hard- or software problem.
Any idea about diagnostics or experiences with this strange behavior?
Best regards
Harald

I’m experiencing similar problems from 3.7.3.
Sometimes it does not show in Foris either.

In my case the ath10k firmware does not load most of the times.
If I reboot using the reboot command the firmware won’t load. I had to power cycle it.
