| Hi all, for some reasons the original e-mail lost all the returns and was unreadable. Here it is posted again. ---------- Hi all, Perhaps somebody can help here. I have a Dell Laptop which worked very well also with the wireless card. In fact the wireless card was never an issue and worked straight out of the box. However it has lost the ability to detect the wireless networks. I have plenty of networks in my area and my little netbook shows them nicely. So did my Dell laptop in the past. - But now the Dell laptop shows no scan results at all although the card seems to be up and running (see terminal output below) - I have to add that I had to compile a module for the WIRED network card which works excellent - I always use and used a wired network and cannot say when the wireless card stopped to work PLUS - I had a faulty harddisk which was replaced by Dell recently so there could be also a hardware fault since then because the laptop was opened by the service people. - And yes the wireless is switched on in the BIOS Any help is appreciated. Feel free to forward this post to other forums if necessary Thanks in advance Chris Here comes the long terminal output sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep irmware ; dmesg | grep ipw; dmesg | grep eth; dmesg | grep ath; dmesg | grep b43; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart *-network description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:0c:00.0 logical name: wlan0 version: 01 serial: 00:1b:b1:44:a3:44 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k latency=0 multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:f69f0000-f69fffff *-network description: Ethernet interface product: AR8152 v2.0 Fast Ethernet vendor: Atheros Communications physical id: 0 bus info: pci@0000:09:00.0 logical name: eth0 version: c1 serial: f0:4d:a2:86:47:8b size: 100MB/s capacity: 100MB/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vpd bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=atl1c driverversion=1.0.1.0-NAPI duplex=full firmware=N/A ip=192.168.1.4 latency=0 link=yes multicast=yes port=twisted pair speed=100MB/s resources: irq:30 memory:f68c0000-f68fffff ioport:df00(size=128) 0: dell-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no lo Interface doesn't support scanning. eth0 Interface doesn't support scanning. wlan0 No scan results auto lo iface lo inet loopback DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04.3 LTS" 00:00.0 Host bridge [0600]: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub [8086:2a40] (rev 07) 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) 00:02.1 Display controller [0380]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a43] (rev 07) 00:1a.0 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 [8086:2937] (rev 03) 00:1a.1 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 [8086:2938] (rev 03) 00:1a.2 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 [8086:2939] (rev 03) 00:1a.7 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 [8086:293c] (rev 03) 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) 00:1c.0 PCI bridge [0604]: Intel Corporation 82801I (ICH9 Family) PCI Express Port 1 [8086:2940] (rev 03) 00:1c.1 PCI bridge [0604]: Intel Corporation 82801I (ICH9 Family) PCI Express Port 2 [8086:2942] (rev 03) 00:1c.2 PCI bridge [0604]: Intel Corporation 82801I (ICH9 Family) PCI Express Port 3 [8086:2944] (rev 03) 00:1c.4 PCI bridge [0604]: Intel Corporation 82801I (ICH9 Family) PCI Express Port 5 [8086:2948] (rev 03) 00:1d.0 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 [8086:2934] (rev 03) 00:1d.1 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 [8086:2935] (rev 03) 00:1d.2 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 [8086:2936] (rev 03) 00:1d.7 USB Controller [0c03]: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 [8086:293a] (rev 03) 00:1e.0 PCI bridge [0604]: Intel Corporation 82801 Mobile PCI Bridge [8086:2448] (rev 93) 00:1f.0 ISA bridge [0601]: Intel Corporation ICH9M LPC Interface Controller [8086:2919] (rev 03) 00:1f.2 SATA controller [0106]: Intel Corporation ICH9M/M-E SATA AHCI Controller [8086:2929] (rev 03) 00:1f.3 SMBus [0c05]: Intel Corporation 82801I (ICH9 Family) SMBus Controller [8086:2930] (rev 03) 09:00.0 Ethernet controller [0200]: Atheros Communications AR8152 v2.0 Fast Ethernet [1969:2062] (rev c1) 0c:00.0 Network controller [0280]: Atheros Communications Inc.
