Answer to "Wireless Airport Card Replacement with New 802.11ac"Hi Guys, I know this is an older post so I apologize for hijacking it. I bought an Early 2009 iMac, 24", 2.66Ghz. I removed the WD 1TB hdd and replaced it with a 2TB SSHD. As above I would also like to possibly update my wifi card. I have a 240mb Fiber Optic connection. With unlimited downloads. At the moment this iMac is getting between 17mb and 24mb speed. My phone gets 50mb over the wifi, and my laptop which is an Acer Aspire 5750 gets 90mb speed. So if I put a gigabit wireless card in this iMac will i get better than 24mb. Thanks for the help.
