i just got my Lenovo Y500 ideapad working with linux. The problem is that wlan doesnt work properly. as soon as my network speed during download hits 200 or 300 kbps the ping rises from 3ms to 4000ms! And then the download speed sinks back to 25 kbps!
watching a youtube video or listen to music during openig some single websiteis not possible. the youtube stream just gets lost and i have to reload youtube.
With my old laptop this never was a problem. I didnt change anything in my network setup like routers or so.
Do you have a clue why the wlan doesn't work properly?
