Hi all.

lspci:
03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000

iwconfig:
wlan0 IEEE 802.11bgn  ESSID:"89" 
          Mode:Managed  Frequency:2.412 GHz  Access Point: 00:1D:73:B1:0A:B1   
          Bit Rate=54 Mb/s   Tx-Power=14 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=69/70  Signal level=-41 dBm

I might be worth looking at this https://bbs.archlinux.org/viewtopic.php?id=125486 thread, maybe related - have you checked your dmesg for microcode errors?

Problem resolved - is was a trouble with my router

If it helps someone: if you set security level to WPA2 without Mixed, router lowers WiFi speed to G. Solution is changing encryption mode from WPA2 to WPA2 Mixed.
