WiFi doesn't work on rax35

[Rickyhu]

Hey everyone.
I have WiFi problem with my router. Internet works well, I can directly put cabel into computer.
One time, I lost my WiFi signal, I rebooted router and after that I have never seen WiFi signal again. I rebooted router and modem lotta times, but result same. I also can't go to the app cuz I don't have a WiFi. And if I'm trying to connect router to PC with ethernet cabel, but it wasn't help me.
I hope that I can fix this with you guys. Thank you in advance.

Have you tried a factory reset? 

Push and hold reset for 7-15 seconds while its powered on.

You can try recoving it with tftp or nmrpflash.  

are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.

and if that doesn't work, you can try using nmrpflash

I tryed to do tftp2 but on the middle of upgrade I got message "unable to get response from the server".
Also i tryed nmrpflash but probably i did something wrong or my knowledges not so good cuz when I tryed to start and i opend exe but I cant writr anything there. There was "press any key to exit"
