Lion and old Broadcom Chips

Hi all,

 

After a few days of research I've finally managed a fresh install of Lion on my friend's Latitude 830, and I have to say it works really well, save for some graphics lag (what can you expect from an Intel X3000). However, when I had installed Snow Leopard on his machine, I used a modified kext which detected his Broadcom 4312, and had OS X use it - no sweat. This time around I re-branded it as an Airport card (which went successfully, though the latest live cd insisted that STA drivers were the only way to go, anyways off topic), but when I rebooted into Lion it did not work. After picking through the IO80211Networking kext from both 10.7.1 and 10.6.8, I noticed that the Lion kext lacked the Brcm4311 kext. After swapping in the IO80211Networking from Snow Leopard into Lion, the wifi card showed up and performed flawlessly. I tried to use just the Brcm4311 kext from Snow Leopard, but it won't load (not compiled from Lion, yadda yadda yadda). I just thought I'd post this for other people who may have had troubles with that. Unfortunately, this driver isn't open source so I do not foresee an easy fix, besides just sucking it up and getting a better wifi card.

@robi62, you 'sneak little devil'; that Broadcom43XXFamilyrev2.kext is actually the same Snow Leopard IO80111Family.kext (v3.1). You just renamed it. I looked at the the Kext package that you enclosed. Ha ha ha!

Way to go to fix the problem! :-)
