115w - WiFi failing every day after firmware update

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 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?

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

     

    In the Wireless Protection Logs, getting

    2017:05:09-23:57:32 sophos hostapd: Configuration file: /var/run/hostapd-phy0.conf
    2017:05:09-23:57:32 sophos hostapd: nl80211: 'nl80211' generic netlink not found

    2017:05:09-23:57:32 sophos hostapd: hostapd_free_hapd_data: Interface wifi0 wasn't started

    In a shell, getting

    sophos:/root # iw list
    nl80211 not found.

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

  • Can you log a support ticket with Sophos? they need people to tell them issues so that it can make 9.5 better for everyone. Even if you don't have a valid support case I am sure they would be interested to help and see whats going on.

     

    Also, have you tried reinstalling the 9.4 iso and does it come back?

    That was my first thought, but as a Home User I don't have that option. On the support page, under Home Users it says

    Important: We currently do not provide phone or email support for our free products and tools.

    You can find online documentation and videos as well as support through Sophos Community

    Hence my post to this thread (which was pretty close so I didn't want to open a new one). You're right though, I should probably put a link to this issue on the 9.5 thread

    StealthyM said:

    Probably my second next step. First is trying to figure out the driver / module - it'd be ideal to move forward.

    Thanks for your reply StealthyM

     
  • 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!

    Many thanks Humberto, 
     
    will give this a shot...
  • I'm glad this works for you but it doesn't work for me.

    I have tried all the items in the below article even though I did have everything set up in the 1st place.

    How to configure the UTM SG-W series internal wireless card with Bridge-to-LAN

    https://community.sophos.com/kb/en-us/122080

    I've got a bunch of these units that were upgraded to 9.5 and they are now all broken. I opened a case with Sophos support and the only theory they had was to try adding the wireless devices to the /etc/modules file. In other words they don't have a clue but they recommended your suggestion.

    All they would confirm was that they broke their own piece of hardware with their own software and they have not got a fix yet. The tech was hoping that it will be in the next 9.5 up2date release in the next 2 or 3 weeks.

    In the meantime can you or Bob or any of the other UTM super techs offer me some other suggestions on how this thing might be made to work or is downgrading to 4.9 or waiting out their malfeasance the only true options?

  • I've read that adding the ath9k to modules isn't enough.

    Edit:

    /etc/hostapd/hostapd.conf-default

    look for:

    ht_capab = [<HT_CAPAB>]

    change to:

    ht_capab = [<HT40 +>] [<SHORT-GI-40>] [<TX-STBC>] [<RX STBC1>] [<DSSS_CCK-40>]

    then edit:

    /etc/modules

    add:

    ath9k

    Restart the MDW services using "/etc/init.d/mdw restart"

    I had not had a chance to try this yet but if you already have the 9.5x release then it's worth it to try.

    Update:

    After trying the above procedure on my own UTM, it didn't work initially. Found another post on Sophos Community with the following ht_capab:

    ht_capab=[HT40+][SHORT-GI-40][TX-STBC][RX-STBC1][DSSS_CCK-40]

    After a reboot, wifi is back up and running.

  • Thanks Exp3371.

    Seems worth a try.

    Can you link us to where you read this from further reading?

    Also, Can anyone explain what this actually doing?

    Also, can anyone confirm success after having tried this?
