Lenovo Wireless not detected

[siroya]

Hi

I have been using Ubuntu at my home laptop (Dell) have had no problem. However, recently I installed 11.04 in my office laptop - Lenovo B450, but 'm unable to connect thru wireless.

It is simply not detecting the wireless. I have a dual boot with Windows 7. Windows 7 detects wireless (surprisingly).

I have tried configuring the network connection in all possible way (manual / auto).

Please Help

Ouch! I hope we don't have to undo much.

Please open a terminal and run and post:

lspci -nn

We'll track down that wireless!

Can you help me out

[chili555]

Please post:

dmesg | grep b43
rfkill list all

The pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

[eipmoc]

it says this

0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

[chili555]

How about the first command?

[eipmoc]

nothing, it goes to the next line, no data er something

[chili555]

Please do:

sudo modprobe b43
dmesg | grep b43

I'm a bit mystified.
