115w - WiFi failing every day after firmware update

ipzipzap

Hello,

I am running a 115w on 9.411-3 with the internal WiFi at 2.4GHz and bridged to AP LAN for over a year now with no problem at all, but since about one week I have noticed that the wifi keeps failing almost every day on almost the same time (19:00-21:00 in the evening). Changing the configuration to force the AP to get reconfigured hasn't helped. The only solution I found is to reboot the whole device.

The only thing I did in the past was the firmware updates, so I blame Sophos for it. Has anyone noticed problems with one of the latest firmwares and the internal WiFi?

If necessary I can provide my logs.

 

Any help would be greatly appreciated.

Dino

    I just found these lines in my log:

    (I changed the SSID names)


    After these, the WiFi won't work until a reboot.

    Dino, sometimes the Up2Date process mangles part of a configuration.  Try restoring the configuration backup made just before the last time you applied Up2Dates.  Any luck with that?

    Well they have now released the proper iso for 9.5. Perhaps try that?

    I'm installing 9.5 from iso as we speak, I'm curious if it changes anything. I've got a 9.4 iso on stand-by, that's the next step. I'll update the thread with the results.

    I can confirm now that 9.500-9 breaks WiFi on SG-115w with the error I've posted above (even after reimage from ISO)

    I had to reimage the 115w to 9.413-4 to get WiFi back.

     

    I'd be happy to report this to Sophos Support but I am a Home User and I haven't found  way to contact their support with this type of license.

     

    Thanks  for your help.

    I know your previous comment was addressed to OP but just to provide some info from my side:

    Hi Dino,

    If restoring the configuration backup made just before you applied the Up2Date(s) didn't fix this, I would definitely get Sophos Support involved.

    Before reimaging I've tried restoring the backup just before Up2Date and it didn't fix the issue.

    Had same issues and found in a German forum to add athk9 (my case) or athk10 to /etc/modules file and reboot unit....

    working fine now on 9.5...

    Hi, Humberto - you've apparently been around for awhile, but welcome to the UTM Community!

    Thanks for sharing that!

    Cheers - Bob

    The upgrade (Up2Date) to UTM 9.500-9 earlier this week (May 8, 2017) has completely broken WiFi on my SG-115w:

    ... 

    Anyone else experiencing similar issues? I'm still investigating, will post findings here.

     

    Yes. I did the update today and can confirm that 9.500-9 has also broken the WiFi in my SG115w.

    I had the same issues when upgrading to 9.5 on my SG105W. 

    I tried to add both athk9 and athk10 with no success. 

     

    After looking in the Active Access Points list, I could see my AP listed as "ath9k", instead of "athk9"

     

    After adding ath9k to the /etc/modules file, followed by a reboot, my WLAN came back to life.

    Same here:

     

    So it seems that the root cause of this bug is a simple typo. 

    I will not add it manually to /etc/modules and wait for a new firmware. Luckily I also have an AP30 which I can use until there is an update.

    Ok, ath9k is correct. It's the Linux driver for Atheros 802.11n PCI/PCI-E devices

    https://wiki.debian.org/ath9k

    Maybe Umberto just had a typo in his post.
