Hi! I installed Ubuntu 9.10 on my Acer 5024wlmi and followed Linux wireless instructions to enable my Broadcom AirForceOne BCM4318 wifi card. Now the wireless adapter is on (laptop front led also is on), I can see wifi networks but connection fails (even with a simple ad-hoc open wifi network!). I tried with Network Manager/WICD/Wifi Radar and also using terminal lfconfig/lwconfig commands without success. It seems that my wifi card cannot ping access points: for example see this log from WICD connection session: -2010/01/16 22:51:15 :: Connecting to wireless network Winx -2010/01/16 22:51:15 :: ping -q -w 3 -c 1 192.168.0.1 -2010/01/16 22:51:17 :: iwconfig wlan0 -2010/01/16 22:51:18 :: Connection Failed: Failed to ping the access point! Here there are some useful data about my laptop/Ubuntu configuration. Hope you can help! ------------------------------------------------------------------------------------------------------------------------------------------ Laptop model >> Acer Aspire 5024wlmi laptop giuseppe@giuseppe-laptop:~$ lsb_release -d >> Description: Ubuntu 9.10 giuseppe@giuseppe-laptop:~$ uname -mr >> 2.6.31-17-generic i686 ------------------------------------------------------------------------------------------------------------------------------------------ giuseppe@giuseppe-laptop:~$ sudo lspci | grep 'Broadcom' 06:05.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) ------------------------------------------------------------------------------------------------------------------------------------------ giuseppe@giuseppe-laptop:~$ sudo iwconfig wlan0 wlan0 IEEE 802.11bg ESSID:"" Mode:Managed Frequency:2.462 GHz Access Point: Not-Associated Tx-Power=20 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 ------------------------------------------------------------------------------------------------------------------------------------------ giuseppe@giuseppe-laptop:~$ sudo lsmod | grep "b43" b43 122168 0 mac80211 181140 1 b43 cfg80211 93052 2 b43,mac80211 led_class 4096 3 acer_wmi,b43,sdhci ssb 35364 1 b43 ------------------------------------------------------------------------------------------------------------------------------------------ giuseppe@giuseppe-laptop:~$ dmesg | grep b43 [ 2.717660] b43-pci-bridge 0000:06:05.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 [ 14.884317] b43-phy0: Broadcom 4318 WLAN found (core revision 9) [ 16.516094] b43 ssb0:0: firmware: requesting b43/ucode5.fw [ 16.739725] b43 ssb0:0: firmware: requesting b43/pcm5.fw [ 16.745578] b43 ssb0:0: firmware: requesting b43/b0g0initvals5.fw [ 16.751202] b43 ssb0:0: firmware: requesting b43/b0g0bsinitvals5.fw [...] [ 4300.736074] b43-phy0: Loading firmware version 410.2160 (2007-05-26 15:32:10) [ 4300.776488] Registered led device: b43-phy0::tx [ 4300.776531] Registered led device: b43-phy0::rx [ 4300.776575] Registered led device: b43-phy0::radio ------------------------------------------------------------------------------------------------------------------------------------------ giuseppe@giuseppe-laptop:~$ sudo lshw -C network *-network:0 description: Network controller product: BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller vendor: Broadcom Corporation physical id: 5 bus info: pci@0000:06:05.0 version: 02 width: 32 bits clock: 33MHz capabilities: bus_master configuration: driver=b43-pci-bridge latency=64 resources: irq:21 memory:c0204000-c0205fff *-network:1 description: Ethernet interface product: RTL-8169 Gigabit Ethernet vendor: Realtek Semiconductor Co., Ltd. physical id: 7 bus info: pci@0000:06:07.0 logical name: eth0 version: 10 serial: 00:0a:e4:e8:a2:87 size: 1GB/s capacity: 1GB/s width: 32 bits clock: 66MHz capabilities: pm bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=full ip=192.168.0.242 latency=64 link=yes maxlatency=64 mingnt=32 multicast=yes port=MII speed=1GB/s resources: irq:23 ioport:a000(size=256) memory:c0209400-c02094ff memory:44000000-4401ffff(prefetchable) *-network description: Wireless interface physical id: 1 logical name: wlan0 serial: 00:14:a4:49:c7:fc capabilities: ethernet physical wireless configuration: broadcast=yes multicast=yes wireless=IEEE 802.11bg ------------------------------------------------------------------------------------------------------------------------------------------ giuseppe@giuseppe-laptop:~$ sudo iwlist scan (...) wlan0 Scan completed : Cell 01 - Address: 02:1D:E0:00:08:5A Channel:11 Frequency:2.462 GHz (Channel 11) Quality=62/70 Signal level=-48 dBm Encryption key:off ESSID:"Winx" Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s Bit Rates:6 Mb/s; 9 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s 36 Mb/s; 48 Mb/s; 54 Mb/s Mode:Ad-Hoc Extra:tsf=00000001035383eb Extra: Last beacon: 272ms ago IE: Unknown: 000457696E78 IE: Unknown: 010482840B16 IE: Unknown: 03010B IE: Unknown: 06020000 IE: Unknown: 2A0100 IE: Unknown: 32080C1218243048606C IE: Unknown: DD070giuseppe@giuseppe-laptop:~$ sudo iwlist scan050F202000100 ------------------------------------------------------------------------------------------------------------------------------------------ giuseppe@giuseppe-laptop:~$ sudo /etc/init.d/networking restart * Reconfiguring network interfaces... -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
