LL7.6 on Macbook (Mid 2009) with WiFi module BCM4322

[oldgaz]

After installing LL76 on the above Macbook the Wifi worked fine without the third party driver. 
I then did a complete Update of some 200 modules which wiped out any wifi.
I have tried the third party driver offered in Driver update (Broadcom STA wireless) but this didn't help.
Is this a known issue and if so, could you please list the steps (in detail) I need to take to rectify the issue. 
Thankyou.

Is this a known issue and if so, could you please list the steps (in detail) I need to take to rectify the issue.

On the hardware db, there are 400 odd reports of systems using bcm4322, of which 180 odd are macbooks with more than a dozen systems reportedly using series 7. Unless someone with the same hardware has had the same issue and reads your post and is prepared to help, it is unlikely that you'll get a detailed list of steps.

Debugging an issue like this over a forum is likely to be time consuming and without any guarantee of a fix, but if you are prepared to engage we can try. Key will be finding the what caused the problem.
Do you have a System Restore point taken before the update/upgrade ?

Otherwise, this guide is perhaps closer to what you are looking for and may help. It covers the kind of questions we'd need to ask.

Although the question is old, the answer appears to have been kept updated and might be worth a read.

G'Day stevef,
Firstly, apologies for not finding the information that you referred to. I did try a Search but came up "empty" so being new to the forum, I obviously didn't do the Search properly.
Just a bit of back ground - I volunteer for an organisation that takes in donated computers, refreshes them and then pass them on to needy kids or older folk. I ended up with some 20 macbooks on my bench and have been successful in reviving most with LL 7.6. This particular one is the oldest and the only one with the BCM4322 module. Since posting, I have been doing a bit of work on this one, and while I keep rough notes on each device, I have presented the facts a little wrong in my post. I decided to backtrack and tried a Live LL7.6 off one of my installer USBs and found that it had no WiFi. At this point, I realised that I had started the work on the macbooks using LL6.4! So, I rewrote the USB and booted into a live LL6.4 which did support WiFi. So I will begin again from here with a bit of help from the link that you have provided. Thanks.
