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?

lspci -nnk | grep -iEA3 "(wireless|network|wifi)"

04:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 2230 [8086:0888] (rev c4)
        Subsystem: Intel Corporation Centrino Wireless-N 2230 BGN [8086:4262]
        Kernel driver in use: iwlwifi

This is the kernel:

Please provide more hardware information. As we don't own the same laptop as you have we don't know what wireless components are in there. Run lspci -nnk | grep -iEA3 "(wireless|network|wifi)" (in case PCI-connected) or lsusb (in case USB connected) and include this output in your question. Also include the kernel version you're running (uname -a) –  gertvdijk Apr 12 '13 at 11:44
