wireless not connecting, hpG62 laptop.

**abhilashm86** · February 1st, 2011

I can see the connections in the above network, but if i click on that, it does not connect, but keeps on trying??
My system configration of wireless is as follows,

Code:

abhilash@abhilash-G62:~/Documents$ sudo lshw -C network

My iwconfig is as follows,

Code:

abhilash@abhilash-G62:~/Documents$ iwconfig 
lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=18 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          
ppp0      no wireless extensions.

What may be the exact reason and how to resolve?? In my workplace there is dns, i should give the dns setting, even then it won't connect??

But my laptop connects to Wired auto eth0 and usb internet(Tata photon+).
Help me with wireless!!

I'm having the same issue on 2 of my laptops. I have an HP Mini duel booting Ubuntu 10.10 with windows 7 and a Toshiba booting only Ubuntu 10.10. Occasionally when they wake up from sleep mode the Wireless Icon is gone. The hardware is still working on both systems. I know this because I have installed Cnetworkmanager and am able to establish a connection from terminal right away.

Could this be an issue with the Gnome network manager not reloading?

You can try

Code:

sudo /etc/init.d/network-manager restart

to restart network manager. Sometimes it works

I'm able to connect to wireless, needless to say I tried above method long back, but it was unable to install device driver for my card.

I had to manually install drivers from source, then it worked.
