I'm not an expert on this, but seems that your system is ending up using the wrong driver after you install updates. Since you can't use internet after you loose wireless, you can't get the right driver again.
Solution is to download the package(s) you need ahead of time to a USB stick so you have a way to restore the correct driver after the updates. Hopefully, what I have outlined below will work.
Download b43-fwcutter from this page to a USB stick. For 64-bit, click on "amd64". For 32-bit, click on "i386". Then just pick a download mirror close to you from list.
Download firmware-b43-installer from this page to a USB stick. For 64-bit, click on "amd64". For 32-bit, click on "i386". Then just pick a download mirror close to you from list.
NOTE: Assuming you are not connected to internet during instructions below, you will inevitably get warning/error messages during the procedure. Close the warnings and ignore them -- just follow the instructions.
Boot into LL and open the Synaptic Package Manager (Menu -> System -> Install/Remove Software). Enter "bcm" into the search box and look at the listed results.

If any of the ones shown in the red box (above) are indicated as installed (with a green check box next to there names), click their box(es) and mark them for "Complete Removal"; then hit "Apply".
If "b43-fwcutter" and/or "firmware-b43-installer" are listed and shown as installed (in addition to any of above), leave them there for now and restart the computer after the others have been deleted. See if wifi works now.
If "b43-fwcutter" and/or "firmware-b43-installer" are the ONLY ones listed and shown as installed, then I'm not sure what problem is. Try removing them, then reboot, then install from ones you downloaded to USB, reboot again.
If still not working, go back into Synaptic and delete the b43 packages. Reboot again. After reboot, plug in USB with your downloaded packages and install both. (Not 100% sure if you need both, and not sure if order of install makes any difference. If had to guess, I'd say install b43-fwcutter first.) To install, right-click on them and choose "Open with GDebi Package Manager", then follow instructions. (All dependencies needed by those packages should already be present on your system, so the installs should work with GDebi disconnected from internet.)
Reboot again and see if wireless working.
