[SOLVED] wireless problem with Broadcom BCM94311MCG wlan mini-PCI [14e4:4311] (rev 0

[harshaambati]

I was successfully able to use wireless on my Broadcom Corporation BCM94311MCG wlan mini-PCI [14e4:4311] (rev 02) with fix from
http://www.ubuntu1501.com/2008/04/nd...rdy-heron.html (From dmizer)
until lately i don't see any wireless networks available to connect
i pretty much don't know what i was doing wrong or what i did do to screw up the wireless....but i see that my card was being recognized in the restricted drivers (or hardware drivers) list it was not there before ( i mean before it didn't even recognize my broadcom driver as restricted driver..i had to use the fix above... i think maybe its because of the updates, the driver suddenly show up in restricted drivers.. i removed the wireless fix and ndiswrapper..and enabled the hardware driver (restricted driver) for wireless( i.e. installed b43-fwcutter).. surprisingly it recognizes my wireless devices..but doesn't show any wireless networks for me to connect to...

Can any one help me....

here is what i get for $ iwconfig
