Wireless not working after update
I've been using Ubuntu and, lately Lubuntu, for about seven years.
On my HP Mini netbook there's Lubuntu 12.04.2 LTS with Kernel 3.2.0-37 generic i686. Wireless is Broadcom Corp. BCM4313 802.11 b/g/n and the PCI-ID is [14e4:4727] (rev 01). Installed driver is wl and I use Wicd.
Everything worked flawlessly (including my wireless HP printer) until a couple of days ago. At that time I was notified that an update was available. Using the Update Manager I proceeded to update my system, as I usually do in this case.
After updating I noted a erratical behaviour of the wireless. It would not work on a first login, but it will work normally after rebooting. Sometimes it will work OK without rebooting. The printer stopped working altogether in all cases.
I usually take a look at what the update is about. In this case I recall that the Kernel was updated and the Broadcom drivers too. Unfortunately I do not know how to check again the contents of this last update.
It seems obvious that updating somehow scrambled my settings producing the described behaviour. I tried reading similar posts, but most refer to a complete installation from scratch failing to work. This is not my case, as everything worked OK before updating.
Any help with this issue will be much appreciated.
