Reinstalling LL after losing wifi due to installing updates

[bobw]

I'm experiencing a similar problem today.  I already have 64-bit LL2.0 on a PC, and today I have installed the 32-bit version on an elderly Dell Inspiron 1525 laptop as a dual-boot with Windows Vista.  At first the wireless connection was working OK with the installed LL (I succeeded in synching my Google & LastPass accounts), then it stopped working.  The wireless connection still works in Windows and when I boot from the LL CD.

I've followed the instructions in Post #2 from gold_finger, and the results of the inxi -nz command, in the installed LL, are:
Network:  Card-1: Broadcom BCM4311 802.11a/b/g driver: wl
          IF: N/A state: N/A mac: N/A
          Card-2: Marvell 88E8040 PCI-E Fast Ethernet Controller driver: sky2
          IF: eth0 state: up speed: 100 Mbps duplex: full mac: <filter>

The command "lspci -nn -d 14e4:" suggested by misko_2083 returns no result.

I have also installed the firmware-b43-installer as per Misko_2083's Post #13, and rebooted without the ethernet cable, but the  wireless connection still doesn't work.

Incidentally, if I need to reinstall, could I use the 64-bit LL2.0?  There is a system report attached - it suggests that the CPU has 32-bit and 64-bit operating modes.
