hello every body....
I hv installed ubuntu 11.10 inside window 7(home basic 64 bit) and i m new user of linux os.I m not able to connect my laptop to the wireless network.though i m able to see the wireless networks but every time i click to connect to the desired network,the netwrk icon at the right top corner of the window changes for connection but after some time it shows msg "wireless netwrk dissconctd or u r offline." i have gone through the UBUNTU HELP option from the HELP menu and tried evry thing it suggested to me frm checking my wireless device status to ip address.In 1 help option i was suggested to enter my internal n external IP adress and to get the internal IP adress i was asked to go to the "connection information(which is gray in colour n not accessible.)" option frm the netwrk manager drop down menu.
I hv also gone through online to fix this problem but could'nt got any solution.i hv not intalled any drivers n how could i without internet connection?

The following are the discription of the netwrk manager:

From the drop down menu on the desktop it says 'Wired Network' and then underneath it 'disconnected'. Underneath that it says 'Wireless Networks' and below that it says 'disconnected'.The options below that are 'Connect to Hidden Wireless Network', 'Create New Wireless Network...', 'VPN Connections', 'Enable Networking' (with a check mark next to it), 'Enable Wireless' (with a check mark next to it), 'Connection Information' (which is greyed out) and 'Edit Connections'.

The following r my laptop configuration:

Model-DELL N-5110
Prosessor-Inter(R)core(TM)i3-2310M CPU@2.10ghz
RAM-3gb
System -64 bit

pls help me to solve my problem...i hv lot of expectation from ubuntu.pls guide me as i m new to ubuntu.

It sounds as if you are using Wubi.

In Ubuntu, open a terminal and run the command lspci (list pci devices) here. It should show the wireless chipset (since that's a Dell, I'll give a dollar to a doughnut that it's Broadcom).

Post the lines about the wireless here (please remember to surround it with "code" tags, which become available when you click the "Go Advanced" button at the bottom of the "Quick Reply" window).

That information will help persons help you.

I can't connect my lapy to the internet .....so is there any body who can help me????????

I've been given an old HP Compaq nx7400 and wanted to wipe it of WinXP & install Ubuntu 10.04LTS for my daughter to play with. Ubuntu installed OK but I struggled to get the Wi-Fi to work and eventually sorted it. I'm no expert and it took me hours to sort so I wanted to share my findings. My "Enable Wireless" was greyed out, I found lots of advice about changing lots of setting but nothing worked, it turned out to be a BIOS issue. By changing the WLAN switching setting in the BIOS all was sorted...

Built-In Device Options:
Embedded WLAN Device Radio > Enable
LAN/WLAN Switching > Disable

Note the following from terminal before BIOS changes:

~$ lspci...
10:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

~$ rfkill list...
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

After BIOS change:

~$ rfkill list...
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

I found a thread in the Ubuntu forums that might help:

http://ubuntuforums.org/showthread.php?t=1901104

Before trying that, though, try this: Open the synaptic package manager (if it's not on the menu, run sudo synaptic from a command line) and go to Settings-->Repositories-->Ubuntu, then open the Gnome Control Center (gnome-control-center from the command line) and click on the "Additional Drivers" item.

Sorry to be so long getting back to you. Life's gotten complicated. Good-complicated, but still complicated.
