I won't hazard a guess. But tell about this big download. Torrents?
So i use a pen wifi, and it works fine, until i download a big game or movie, after i download it, my internet doesn't work anymore for ever, like i get hugeee ping spikes in games, a lot of not responding network, first time this happened to me i change the pen wifi usb entrance, and it work fine again, then i downloaded a big game again and it started happening again, i never saw this kind of error and im out of solutions, im running W10.
i already tried all usb entrances, no result
