wifi issiues with thinkpad x201 tablet

I'm having constant disconnects form wifi including airplane mode switches. Been fighting this issue for last 2 weeks but giving up every time unable to find correct answer. I even desperately tried ubuntu mate 15.04 live cd but same problem occurs so at least I know is not my beloved arch linux. Now I'm here asking if anyone can help?

This is output of my journalctl from moment of disconnecting:

Re: wifi issiues with thinkpad x201 tablet

If the problem also occurs in the live environment then that would suggest a hardware issue.

Is the card connected & seated properly?

FWIW, I'm posting this from an X201 running Arch [testing] and the wireless has always worked flawlessly without any tweaking.

Re: wifi issiues with thinkpad x201 tablet

what wireless card have you got? 

 lspci
Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)

It's probably hardware failure since I tested on my alfa wifi card and works flawlessly

Re: wifi issiues with thinkpad x201 tablet

It's actually broken even on cable using w eth0. Anyone have any ideas what it might be?
