[SOLVED] Kodi 17.6, no more wifi?

[ThePumisher]

Got the same problem (with the small difference that i'm still on 17.4 and not on 17.6) after installing the latest system-update and performing a restart, and the solution for me was also changing the ssid name from "Martin Router King" to "MartinRouterKing" first on my router and then on xbian via sudo nano /etc/network/interface
Now Kodi is able again to search for networks. But what i don't understand - there are plenty of networks with no blank in the ssid and Kodi couldn't find them before.

edit: one minute later and it's broken again
edit2: aaand it seems that i can't get it running again
