Fixing wifi at my Dell Inspiron E1505

This is a common issue among Linux users. Every time you make a fresh install there is big chance that your Wifi will not work. This was the case for me when I removed the partitioning and decided to go all UBUNTU. The fix was reasonable (after finding the right solution of course)

first step, know exactly what is your Wifi drive:

$lspci -v
Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
    Subsystem: Dell Wireless 1390 WLAN Mini-Card [1028:0007]
    Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx-
    Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR-     Latency: 0, Cache Line Size: 64 bytes
    Interrupt: pin A routed to IRQ 16
    Region 0: Memory at efdfc000 (32-bit, non-prefetchable) [size=16K]

so my drive is The infamous Broadcom BC4. Now I need to install it

$sudo apt-get install firmware-b43-installer b43-fwcutter

then a reboot is in order (it is better to disconnect the Ethernet while doing this step)

now try turning it on
$sudo modprobe b43

Tada! Know it can see the signal and life is good.
