wlan problem, wifi disconnecting?

hi, it's the same problem everyone else have been facing except that i cant fix my problem the way they did

after connecting to wifi using:

ip link set wlan0 up
wpa_supplicant -c /etc/wpa_supplicant.conf -i wlan0 -B
iwconfig wlan0 essid my_wlan
dhcpcd wlan0

surfing web is okay, but when i try to install eclipse using:

pacman -S eclipse

pacman starts downloading packages(around 100Mb) after 2seconds, download speed begins decreasing(from 500kb/s to 1000bytes/s), and finally disconnecting totally.

dmesg says:
[ 1801.055549] wlan0: moving STA 00:22:b0:d6:1d:8f to state 1
[ 1801.055553] wlan0: moving STA 00:22:b0:d6:1d:8f to state 2
[ 1801.055558] wlan0: moving STA 00:22:b0:d6:1d:8f to state 3
[ 1811.052278] wlan0: deauthenticating from 00:22:b0:d6:1d:8f by local choice (reason=3)

lspci:
Network controller: Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe

uname -r:
3.3.4-2-ARCH
it was a bug in 3.3.1, it's supposed to be fixed in 3.3.2+, why am i having difficulties?
what should i do?

Re: wlan problem, wifi disconnecting?

Are you using power management on your wlan interface? If so, try disabling it and see if that makes a difference.

Re: wlan problem, wifi disconnecting?

Is it exactly 5 minutes?  Is the router using an absurdly low lease time (like 300 seconds)?

Re: wlan problem, wifi disconnecting?

i don't remember 'installing'/'activating'/'set a power manager on wlan0', how do i check?
lease time is fine, it's 1 day (it works fine in ubuntu and windows)

by the way, i installed rt3090 driver, no change

You can check the status of power management via "iwconfig <interface>".
