I recently got a notebook which has core2duo 1.6ghz ,2g ram,graphic x3100.
This is my first notebook .
I installed Lion 10.7.3 without problem.
Lion is the only os that could be installed on that notebook.
I changed the wifi card to r9281.
It works without any modification,but transmit rate is set to 58 and locale is unknown.
My router is airport extreme.
I'm using smbios of macbook 3,1 but system information shows macbook air original.
I don't have windows installed.
Is this transmit rate normal? if not any suggestions to fix that?

I tried dsdt fix.
But after that airport can't find networks.
Maybe my dsdt fix is wrong. There's no arpt in ioreg.
Here's my ioregistry before fix, and my dsdt after fix.
Would you check this for me?
