Morning All.

 

I have been looking for a small usb wifi dongle for the last few days and was going to purchase this from ebay.

USB Wifi N Mac/Win7

 

but would rather an internal solution if possible.

 

i have a Sony Vaio VGN-A397XP with an Intel BG2200 MiniPci 3B Wireless Card which is currently unsupported by OS X 10.5

 

 

Intel 2200BG Product Brief1. Is it Possible to swap the card out and replace with an os x compatible model? (the card can be removed i have taken it out only just yesterday to check) but i just need clarification that there are no bios or whatnot blocks?

 

2. What is the best 'N' 'MiMo' MiniPci 3B card supported by 10.5.8 Leopard? (and Snow Leo when i try that out)

 

3. Can a 3b card Fit a 3a Slot and vice versa. i have plenty of room inside if that is the only problem?

 

Thanks for any hep and advice. its much appreciated.

Some are Atheros and some Ralink Modules.
