For some days my smartphone (Android) no longer finds my WLan network (does not show it anymore and does not connect). My Playstation has the same problem. On my notebook, however, everything works as usual. Restart of router (EasyBox) and mobile phone have brought nothing. What else could I try?
Yesterday I already answered a similar question, the only thing you can do is wait, if your router is reset and it still does not work, then there's not much that you could do, except 10 times your phone on and off and then hope that it will work at some point, because I had the same problem with my phone, the next day it went again.
