115w - WiFi failing every day after firmware update

Question

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.

 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 StealthyM 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...

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.

Hello, I have a SG-115W running with Home license. Like everyone else the built in wifi was working great until an update, and I've tried all the possible solutions that everyone posted, it may have worked for a short time or not at all. 
 I had a old SG-115W licenced with a business license. It was fully updated to version 9.505-4. The Built in Wifi worked perfectly. A wifi device would connect properly and obtain an IP address. (On my 115w with home license the SSID broadcasts but can not connect anything to it) 
 So I wanted to try to apply a home license to this working "Business Appliance" 
 SSH and rename /etc/asg to /etc/asg.bak rebooted the appliance. 
 After it rebooted I tried firstly to connect my wifi device to the wifi, and it wouldn't even see the SSID from that unit. 
 So I put the asg back to normal rebooted and wifi was working again. 
 Hit the web, and I stumbled upon this site. https://martinsblog.dk/sophos-utm-use-hardware-appliances-with-home-software-license/ 
 Solution: 
 edit /etc/asg file and remove the line "ASG_ID....." save it, reboot the device, and the built in wifi is still working with home license. 
 unfortunately my other device that isn't working, I had deleted the asg file so I tried recreating the file, but it didn't work. so it looks like I'll have to reload the device and restore from backups. 
 Hope this helps 
 
 Update: 
 So my other SG115 I did a complete reload of the software. 
 Enabled SSH login, 
 Logged in SSH and removed the ASG_ID line from /etc/asg and rebooted the device. 
 Applied my Home license, and restored from backups. 
 And so far, built in wifi is working.
