Description of problem: I get very poor bit rate between my RaLink RT2561/RT61 rev B 802.11g wlan card and wlan router (only about 4 meters between them). With kernel 2.6.25.6-55.fc9.x86_64 I only get a bit rate of 2 Mb/s. With previous kernels (e.g. 2.6.25.4-30.fc9.x86_64) I get 54 Mb/s. Version-Release number of selected component (if applicable): kernel-2.6.25.6-55.fc9.x86_64 How reproducible: Always Steps to Reproduce: 1. 2. 3. Actual results: Bit rate of only 2 Mb/s Expected results: Higher bit rate, mostly 54 Mb/s Additional info: dmesg output: ADDRCONF(NETDEV_UP): wlan0: link is not ready wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:19:5b:e5:2e:f0 wlan0: RX authentication from 00:19:5b:e5:2e:f0 (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:19:5b:e5:2e:f0 wlan0: authentication frame received from 00:19:5b:e5:2e:f0, but not in authenti cate state - ignored wlan0: RX AssocResp from 00:19:5b:e5:2e:f0 (capab=0x421 status=0 aid=2) wlan0: associated wlan0: switched to short barker preamble (BSSID=00:19:5b:e5:2e:f0) ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:0f:66:c7:a4:ef wlan0: RX authentication from 00:0f:66:c7:a4:ef (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:0f:66:c7:a4:ef wlan0: RX AssocResp from 00:0f:66:c7:a4:ef (capab=0x411 status=0 aid=1) wlan0: associated wlan0: switched to long barker preamble (BSSID=00:0f:66:c7:a4:ef) wlan0: No ProbeResp from current AP 00:0f:66:c7:a4:ef - assume out of range wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:0f:66:c7:a4:ef wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:0f:66:c7:a4:ef wlan0: RX authentication from 00:0f:66:c7:a4:ef (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:0f:66:c7:a4:ef wlan0: authentication frame received from 00:0f:66:c7:a4:ef, but not in authenti cate state - ignored wlan0: RX ReassocResp from 00:0f:66:c7:a4:ef (capab=0x411 status=0 aid=1) wlan0: associated
With kernel 2.6.25.10-86.fc9.x86_64 the problem is gone. Bit rate is back at 54 Mb/s again.
Thanks for the report!
