I have a mid 2012 MacBook Air and the wireless recently started being very slow. I made sure the router's firmware was up to date and the wireless is still very slow. How can I make sure the firmware the wireless card that came with the computer is up to date? Or can I replace the card somehow? When I look at my computer's specs, it says I have a 802.11n Wi-Fi wireless networking; IEEE 802.11a/b/g compatible. What does that second part mean?

Thanks!

the WiFi card in the 2012 Air is a replaceable part.

802.11n is the newest WiFi standard that machine is capable of using. the other letters refer to earlier (and slower) standards that it can also operate on. the latest standard is 802.11ac. faster than n. that is what is included in the 2013 and later Airs.

So I cannot put the 802.11ac into my mid 2012 Air? If not, since I already have the 802.11n in my computer would there be any value in replacing it? it should theoretically stream at the same speed, unless it being 4 years old takes a toll on it. Is there any test I can do on my computer to check how the current wireless card is functioning before just replacing it with the same one?

it looks that you cannot upgrade to ac on that Air. and to make use of it you would need to have an ac capable wireless router. it's unclear where you actual problem is. more likely your router than the Air. can you try the computer somewhere else to gauge the performance on a different network?
