Hello, Vinich and thank you for reaching out.
I am sorry for not being familiar with Russian, so I used Google translate to understand.
Please refer to [Phone/Pad] What to do if my phone won't connect to a Wi-Fi network? first for troubleshooting the Wi-Fi issue you might have.
Meanwhile, please PM me with the serial number of your phone, the city and country you purchased your phone in, and more detailed information.
Thank you!
