If it no longer works with the live USB, but used to, and you have not
changed anything on the USB stick then it must be a change on the
laptop hardware or bios. I presume that if there is a hardware switch
that it is switched on. Check in the BIOS settings that it has not
got switched off there. Is it setup for dual boot with windows? If
so does it work there?

It is not a dual boot system.There is only Ubuntu 11.04 now I
formatted it completely with 11.10 but the same situation persists.

That is not surprising given that it no longer works with the Live
USB, so it is something on the laptop that has changed or broken. You
didn't answer the other issues.
Is there a hardware switch for the wifi.
Have you checked in the BIOS to see if anything there mentions wifi?

There is a hardware switch but I am very sure that it is not turned
off Since bluetooth icon is there and
other bluetooth devices can detect my laptop.

I did check bios but there is no such option to disable wifi .

Yes I have seen and wifi there is not switched off.

I noticed this problem started since I did suspend and resume of my
laptop i.e. close the flap of laptop and then reopen it.It is this
time that laptop gets suspended and and resume again.

After this I erased entire Ubuntu 11.10 from my system and did a clean install.
Installed STA driver from the additional drivers section.After this
got my wireless working.But I as soon as I close the flap of laptop
and then reopen it again the connectivity goes and rfkill list command
shows

rfkill list
0: brcmwl-0: Wireless LAN
Soft blocked: no
Hard blocked: yes

and then onwards I can not connect to any kind of wireless network.I
did not switched off the wifi button as rfkill command above shows
Hard blocked.
Now I do a reboot and then wait for some time.First attempt to connect
to available wireless network fails.After some time it is able to
connect.
and this time rfkill list shows

rfkill list
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no

I have not at all touched the hardware wifi switch.If you notice
closing the laptop flap while working and reopening causes this
problem.This seems to be some problem in STA driver power management
module.

Check your BIOS if it has an option called "Airplane mode". If it has
it, disable it.

It would be great if we knew what laptop model you have, so as to have
a look at its BIOS settings in its manual, on line.

Earlier you said that it no longer works on the live USB boot whereas
it used to work with that. That does not seem to be consistent with
what you are saying now.

What have you set should happen on closing the lid? Suspend or
Hibernate? If you do that (whichever it is) using the menus does the
wireless keep working in that case?
