i have ubuntu 12.04 installed in my dell inspiron 15R laptop but the wifi is not enabled

i have tried some solutions but it has not worked till now

when i use the lspci -vvv comand i get

08:00.0 Network controller: Broadcom Corporation Device 4365 (rev 01) Subsystem: Dell Device 0016

`Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 0, Cache Line Size: 64 bytes
Interrupt: pin A routed to IRQ 11
Region 0: Memory at c1500000 (64-bit, non-prefetchable) [size=32K]
Capabilities: <access denied>`

the command lspci -vvnn | grep 14e4 gave this output

08:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:4365] (rev 01)

one of the threads also gave a .deb file to install which gave me an error though i am unable to locate that thread now

i have tried installing and uninstalling b43-fwcutter ando also installing and uninstalling

sudo apt-get remove bcmwl-kernel-source

sudo apt-get install bcmwl-kernel-source

dosent seem to work

gksu jockey-gtk also doesn't show any options regarding wifi

i seem to have tried a lot of things and havent kept track so so i dont know the present status of my system :(

i do not know how to use ndiswrapper.

how can i get my wifi working? thank you.

Did you try additional drivers, aka jockey? It worked for my broadcom once.

I assume you were connected to the internet via ethernet when you checked. –  Aaron Oct 23 '12 at 0:23
