Laptop: Lenovo Y50-70, 8.1 x64 up to date
Wireless router: Canyon CNP-WF514N1A
Bluetooth mouse: Logitech M555B
Wifi driver: All of them. One at a time. 17.0, 17.05, 17.1, 17.13
Sometimes, and I mean it, sometimes my speedtest is ~70mpbs. At this point, my download speed is around 8Mb/s and my mouse is barely usable. The cursor slows down an lags but it can be used.
But most of the time my speedtest is around ~30mbps. My download speed is under 3 Mb/s and the mouse is unusable. The cursor has an unbelievable lag and it is basically useless.
I have tried changing the settings in Device manager. I have tried to edit the registry. I have tried to switch Bt off to test the Wifi. No change. I have tried to test Wifi by turning Bt off. No change.
No microwave interference, I barely have GSM signal at my place.
I have tried all the drivers and no driver at all.
The cursor lags when gaming, even with the Wifi turned OFF.
I ran out of ideas. I want it to work. This is the best wireless card I can get In Romania, so I cannot make an upgrade.
