Rodriguez" <mcgrof@...lab.rutgers.edu> Subject: rtl8187 rate control doesn't work Hi Now the compat-wireless-2.6 package is working and I get an Internet connection with my rtl8187 based card. (It's on an ASUS P5B Deluxe) I used the compat-wireless-2.6 package for this log, but I have the same problem with the version integrated in kernel 2.6.24-rc6 The Access Point is some rooms away so the signal is not the best at my location. When starting the device with no fixed rate it wants to connect with 54MBit/s and as iwconfig says it was successful but I can't ping any device in the wireless LAN. (it's the first part of the log) The rate will not be slowed down it stays fixed at 54MBit/s. After starting the device with rate fixed to 11M I get a connection to the Access Point and iwconfig's output looks the same as without fixed rate, but I'm able to ping the all devices in the network. (second part of the log) Now it slows down the rate to 1MBit/s iwconfig looks like this (fixed rate to 11M): wlan0 IEEE 802.11g ESSID:"mehrtenswlan" Mode:Managed Frequency:2.412 GHz Access Point: 00:1A:XX:XX:XX:XX Bit Rate=1 Mb/s Tx-Power=27 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Link Quality=50/64 Signal level=16/65 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 With no fixed rate there is an Bit Rate=54 Mb/s instead of 1Mb/s. With rate fixed to 18MBit/s I have the same problem as with no fixed rate. dmesg log: phy0: Selected rate control algorithm 'pid' phy0: hwaddr 00:15:af:03:ab:79, rtl8187 V1 + rtl8225z2 usbcore: registered new interface driver rtl8187 wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:1a:92:ea:73:12 wlan0: authenticate with AP 00:1a:92:ea:73:12 wlan0: authenticate with AP 00:1a:92:ea:73:12 wlan0: authentication with AP 00:1a:92:ea:73:12 timed out wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:1a:92:ea:73:12 wlan0: RX authentication from 00:1a:92:ea:73:12 (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:1a:92:ea:73:12 wlan0: RX AssocResp from 00:1a:92:ea:73:12 (capab=0x411 status=0 aid=1) wlan0: associated wlan0: switched to short barker preamble (BSSID=00:1a:92:ea:73:12) ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready >>restarting connection with fixed rate 11M wlan0: deauthenticate(reason=3) ADDRCONF(NETDEV_UP): wlan0: link is not ready wlan0: Initial auth_alg=0 wlan0: authenticate with AP 00:1a:92:ea:73:12 wlan0: RX authentication from 00:1a:92:ea:73:12 (alg=0 transaction=2 status=0) wlan0: authenticated wlan0: associate with AP 00:1a:92:ea:73:12 wlan0: RX AssocResp from 00:1a:92:ea:73:12 (capab=0x411 status=0 aid=1) wlan0: associated wlan0: switched to short barker preamble (BSSID=00:1a:92:ea:73:12) ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready wlan0: no IPv6 routers present -- Hauke Mehrtens -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
