No Airport Card Installed error

Hi all, I installed an updated wifi 'N' speed card to my A1150 last week and WiFi worked fine.

I then updated my RAM and added a 1Gb chip from Crucial.

The moment the memory was added my WiFi stopped responding. On the top bar I have the "No Airport Card Installed" message.

If I reset PRAM it reappears... Until next reboot. I've tried everything to get this WiFi working. I've deleted my library/preferences files, taken out the Airport card and replaced it with my old chip (which only has a wifi radius of around 1m) and the old chip works fine (so long as you're no more than two feet from the router).

I've tried running /usr/sbin/networksetup -listallhardwareports

in Terminal and it does not list Airport.

If I run /usr/sbin/networksetup -setairportpower en1 on

I return the error:

"Could not find hardware port or device named en1.

Wireless is not available."

I've read so many posts about the "No Airport Card Installed" error and most say to reset PRAM once and it will be fine. For me I have to do this each time I reboot and that can't be healthy for the laptop.

Any advice would be greatly received.

Try removing the Crucial chip and replace it with the original and see if wifi works correctly. Sometimes ram causes strange problems.

I forgot to mention, i removed the crucial chip leaving my original Mac memory and still the same.

I've reinstalled the OS without the additional memory and repaired permissions.

The only way my Airport card seems to work is by rebooting the PRAM each time the machine is switched on.

Could this be a hardware issue with the Airport card?

Thanks for your help.

I'm not sure what to say here since you state it did function for a while. The problem I see is Mactracker indicates your unit only having firmware for up to a G Airport card. Since it does function with the original card I would look into replacing the original with another card of the same type. Good luck.

what's the date and time listed on your machine?
