I have the latest version of OS on the First generation Turris Omnia - for days prior this incident I was able to get into the WiFi Network Settings in reForis and I was able to click on the Reset WiFi Settings button. Suddenly I can no longer access this on any of my connected devices, iPhone, MacBook, iMac / Safari / Chrome - nothing works! Connected via WiFi to the router or via ethernet cable also makes no difference. I had not touched anything on the router during the week prior me finding out it’s not working. I tried to rollback few days back - nothing helped.
I would be up to some digging around @jklaas but I have no idea where and what to look for. I don’t use ssh to configure the router, only Luci and reForis only for visual check or rolling back or the internet speed info.
Sometimes, when you dont know the answer, please avoid such statements. This has nothing to do with eMMC. From the screenshot, it is obvious that it is related to reForis frontend UI, nothing else is going on.
There could be typos or some invalid values which reForis does not accept for Wi-Fi, if it was configured by hand or in LuCI as correctly pointed out by @jklaas. What is enough is to basically reach the Technical support department as they know how to proceed with issues like these. You can see more details in the browser’s developer console. If you don’t know how or what you should be looking in the developer console, here search button might help.
