Using the kernel 2.6.27-7-generic and version of ubuntu is the intrepid ibex 64 bits. uname -a Linux m1330 2.6.27-7-generic #1 SMP Thu Oct 30 04:12:22 UTC 2008 x86_64 GNU/Linux lspci 00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c) 00:01.0 PCI bridge: Intel Corporation Mobile PM965/GM965/GL960 PCI Express Root Port (rev 0c) 00:1a.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #4 (rev 02) 00:1a.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #5 (rev 02) 00:1a.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #2 (rev 02) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02) 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 (rev 02) 00:1c.1 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 2 (rev 02) 00:1c.3 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 4 (rev 02) 00:1c.5 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 6 (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #1 (rev 02) 00:1d.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #2 (rev 02) 00:1d.2 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #3 (rev 02) 00:1d.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #1 (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev f2) 00:1f.0 ISA bridge: Intel Corporation 82801HEM (ICH8M) LPC Interface Controller (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller (rev 02) 00:1f.2 SATA controller: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801H (ICH8 Family) SMBus Controller (rev 02) 01:00.0 VGA compatible controller: nVidia Corporation GeForce 8400M GS (rev a1) 03:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 05) 03:01.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 22) 03:01.2 System peripheral: Ricoh Co Ltd R5C843 MMC Host Controller (rev 12) 03:01.3 System peripheral: Ricoh Co Ltd R5C592 Memory Stick Bus Host Adapter (rev 12) 03:01.4 System peripheral: Ricoh Co Ltd xD-Picture Card Controller (rev ff) 09:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express (rev 02) 0c:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61) ifconfig wlan0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX inet addr:172.26.0.5 Bcast:172.26.0.15 Mask:255.255.255.240 inet6 addr: fe80::221:5cff:XX43:XXXX/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:9824 errors:0 dropped:0 overruns:0 frame:0 TX packets:6379 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13409640 (13.4 MB) TX bytes:757775 (757.7 KB) iwconfigwlan0 IEEE 802.11abgn ESSID:"Crashbit" Mode:Managed Frequency:2.412 GHz Access Point: XX:XX:XX:XX:XX:XX Bit Rate=54 Mb/s Tx-Power=15 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Power Management:off Link Quality=100/100 Signal level:-22 dBm Noise level=-93 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 iwlist scanning wlan0 Scan completed : Cell 01 - Address: XX:XX:XX:XX:XX:XX ESSID:"Xxxxxxx" Mode:Master Channel:1 Frequency:2.412 GHz (Channel 1) Quality=100/100 Signal level:-18 dBm Noise level=-88 dBm Encryption key:on IE: WPA Version 1 Group Cipher : TKIP Pairwise Ciphers (2) : CCMP TKIP Authentication Suites (1) : PSK IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : TKIP Pairwise Ciphers (2) : CCMP TKIP Authentication Suites (1) : PSK Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 18 Mb/s 24 Mb/s; 36 Mb/s; 54 Mb/s; 6 Mb/s; 9 Mb/s 12 Mb/s; 48 Mb/s Extra:tsf=00000008a2410189 Extra: Last beacon: 52ms ago
