My laptop is both using a wired connexion and a wireless one. I installed dhcps3-server, after that I guessed that there is no wireless network displayed. What can I do to see available wireless networks (I have my own wireless network that is not displayed).
I had the same problem yesterday when I installed dhcp3-server. I checked for solutions on internet but in vain. So I had to reinstall Ubuntu again. I do not want to reinstall it again each time i need dhcp3-server or any other tool.
When I run
nm-tool, I got this (for the wireless part):
NetworkManager Tool State: connected - Device: wlan0 ---------------------------------------------------------------- Type: 802.11 WiFi Driver: ath9k State: unmanaged Default: no HW Address: D8:AF:9A:B7:DA:D9 Capabilities: Wireless Properties WEP Encryption: yes WPA Encryption: yes WPA2 Encryption: yes Wireless Access Points
My wireless device is not disabled by hardware. I run
rfkill list and I got this:
0: phy0: Wireless LAN Soft blocked: no Hard blocked: no
My Ubuntu can see my wireless device also. I run
lshw -C network and I got this (for the wireless part, and you can also see that the driver for wireless adpater is installed):
*-network description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Atheros Communications Inc. physical id: 0 bus info: pci@0000:25:00.0 logical name: wlan0 version: 01 serial: d0:df:9a:5b:da:4a width: 64 bits clock: 33MHz capabilities: bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=2.6.38-8-generic firmware=N/A ip=10.1.18.68 latency=0 multicast=yes wireless=IEEE 802.11bgn resources: irq:19 memory:d4600000-d460ffff
Also, my wireless PCI device is shown (but its driver not working ?) when I run :
Network controller : Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01)
iwconfig and I got these information:
lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=17 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off
How can I resolve this problem (displaying back the wirless networks )?
Note that my wired connexion works well.
