Please it’s not necessary to create another thread. Btw: you created post in your other thread 12 minutes ago.
Next time please for source code or something which is longer use something like pastebin.
Anyway it will be better, when you will copy this and email it to tech.support(at)turris(dot)cz and dont forget to mention something related or include files from this page: https://www.turris.cz/doc/en/howto/error_reporting
They will help you.
my first report was without reaction for one week so I decided to start new one, it is little bit frustrating to spend quite amount for router with so many issues, and had no working support, still missing some stretch goals… Ok next time I will use pastebin and one thread only, but my time is no unlimited, and so is my money reserve. Maybe my TO will be for sell soon with zero support and I can get three WRT boxes instead 
Community Manager from Turris team said that they’re guaranteeing support only on email right now.
Many issues? Name some.
For example WiFi issues was fixed, but this what you posted seems new - They will fix it just send them email. :-).
For Wifi problems, which you had you could get fix faster, when you will opt nightly branch.
Packages will be updated soon (give them month, maybe two) 
And stretch goals needs time. They’re working on it.
Ok will do that. To many issues - my issue is just this one AFAIK, I meant number of reported issues by other owners too. I decided to go forum way to help others with similar issues, but if mail is only support way, I’ll go mail way.
Thx, I will post results here if there are some.
hi, as I promised - result is that last update fixed this issue at least in my case. So my TO can reach uptime 10+ without hiccup, I hope that my fixing days are over and I can enjoy stable and reliable device
