My Lenovo Ideapad s10-3s refuses to connect to anything.

It recognises my wireless card (Broadcomm 4313) but whenever I boot up it shows "Wireless is disabled" under Wireless when I click on the Network icon even after I check Enable Wireless. After I reinstalled the Broadcom driver via Additional Drivers, it now has Enable Wireless greyed out and says "Wireless is disabled by hardware switch" (the hardware switch is on).

I have plugged in my ethernet cable directly but nm-tool says Connecting (configuring IP address) and then it becomes disconnected.

After I run 'sudo rfkill unblock all', under Wireless, it says "Device not ready".

What should I do?

ifconfig: eth0 Link encap:Ethernet HWaddr f0:de:f1:0f:fc:ae
inet addr:10.164.12.120 Bcast:10.164.13.255 Mask:255.255.254.0 inet6 addr: fe80::f2de:f1ff:fe0f:fcae/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4651 errors:0 dropped:0 overruns:0 frame:0 TX packets:2791 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4280041 (4.2 MB) TX bytes:323924 (323.9 KB) Interrupt:16

was able to connect via ethernet on a friend's modem but Wireless remains at "Device not ready"

  1. If you have a wireless switch which you can toggle using your keyboard or in the BIOS, check if that's turned on.

  2. try doing an ifconfig on the gnome-terminal and see if you are getting any io address there. if there is, eth0 or wlan0 will show any ip address other than starting with 169. Also do a ping to check the response. An ifconfig output will be something like the one below:

.

ifconfig   
      eth0      Link encap:Ethernet  HWaddr 84:2b:2k:43:ef:08
      inet addr:10.11.23.80  Bcast:10.20.43.255  Mask:255.255.255.0
      inet6 addr: fe90::832b:2bff:feb5:ef08/64 Scope:Link
      UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
      RX packets:26968 errors:0 dropped:0 overruns:0 frame:0
      TX packets:18958 errors:0 dropped:0 overruns:0 carrier:0
      collisions:0 txqueuelen:1000 
      RX bytes:19431851 (19.4 MB)  TX bytes:3558720 (3.5 MB)
      Interrupt:21 Memory:f7be0000-f7c00000 
  1. If you do get any connection then try this. open /etc/network/interfaces and comment out anything present there.

    gksudo gedit /etc/network/interface

Restart your computer after the changes and see if you get any connection.

no io address from ifconfig. /etc/network/interfaces/ : auto lo iface lo inet loopback –  kibs May 4 '11 at 15:11
    
comment out everything in there and restart your system. lets see what happens then. –  Ubuntuser May 4 '11 at 16:40
