Lately, I have a problem with my optical internet. WIFI usually works on one smartphone. On the other, it doesn't. If I load the Utorrent program, no matter if I right away close the program, the internet will stop working until I reset my router, but if I load the VPN app, torrent and browsing/surfing will generally work on one computer. Still, there will be no connection on the other computer. I never had or heard of a problem like that. It is Nokia optical router, and I'm using Windows 10 with the latest updates.
