How can I fix my Dell laptop's wireless connection?

Question

I've just installed Ubuntu on my Dell laptop, and the wireless is not working.

How could I fix it ? Is there any driver I should install?

Note: I'm also running windows 7 on the same laptop and the wireless connection works just fine.

Any suggestion would be helpful. Thanks!

EDIT : Wifi card model description : vendor : broadcom corporation product : BCM4312 802.11b/g LP -PHY version : 01 configuration : driver = b43 -pci-bridge latency=0

follow the below link https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx

Here go to the section b43: No internet access follow the steps in this section. Note: b43 fwcutter is a must so without step 1 do not proceed to further steps.

Once done with all 4 steps goto the section switching between drivers: Herein remove (if existing) drivers. It might happen that some driver will not be there. for my case: after doing sudo modprobe -r wl I got error: FATAL: wl not loaded. So not to worry Then do loading them, by following the commands.

Once you are done please check: 1) sudo rfkill list all if it shows as below: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes

Hard blocked yes means there is hardware switch on your computer/laptop which has disabled the wifi. With this : Hardware swicth blocked can be seen under wireless icon. Now to turn it on read below: for my case: dell inspiron 1525, press Fn+Alt+F2 to turn on the wifi.

Thanks
