You guys are gods!!!
All working perfectly on my Compaq Evo N800v running a 3Com OfficeConnect Wireless PCMCIA card.
This is what I did (I also found I was unable to directly edit the files in the text editor) - (please forgive me if I've basically repeated what has already been said - I'm a support guy - I have to log faults with software every day, so I tend to be a bit thorough with details
- Launched the Terminal window.
- Typed: sudo nano /System/Library/Extensions/IO80211Family.kext/Contents/Plugins/AppleAirPortBrcm4311.kext/contents/info.plist
- Changed the following lines:
(ditched the last line)
- Ctrl+0 to save, [Return] to use offered filename (ie, what it already is)
- Ctrl+X to exit whatever this command line editor is called
- Restarted osx86
- Launched the terminal window again.
- Typed: sudo nano /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
- Changed the line which reads:
If there is an additional interface already using en1, change it to en2 and the integer to 2 (this worked for me)
- Ctrl+O to save changes, [Return] to accept filename.
- Ctrl+X to exit editor.
- Restart osx86
- Open Network Preferences - It should say it has detected a new Airport interface, or something, say OK.
- Click Show, select Airport.
- Click Apply Now.
You should now have full Wireless network access.
Thanks for all yer helps
