I recently did a fresh install on it. I replaced the stock Ralink wi-fi with AR9280 (I only need the wi-fi and I ordered a separate BT 4.0 USB dongle). Everything was fine, I was using my home 5GHz connection. It was somehow slow to connect after reboot (around 10-20 secs), but then it was working.

A day ago I started having huge issues with the wi-fi unable to find ANY network. I double-checked antenna cables, reseated it, but still the same. I thought the problem started after sleep, but then I tried to reproduce it without success.

I managed to revive the connection a few times by pressing the wi-fi button (its always yellow now, but i think it was white before my OS X install), but this doesn't always work.

I tried to remove the wi-fi from the SysPrefs and add it, but the problem remained.

I have a keychain icloud enabled and my mac automatically gets all the networks that my phone has ever connected to, so I decided to delete all networks. And then it worked all of a sudden. This time I decided to connect it to the 2.4GHz AP, and connection after reboot is instant. No problems after sleep whatsoever.


My question is: Is this a known issue for this card only for 5GHz? Should I order a Broadcom one? The 2.4 wireless spectrum around me is really stacked, so I prefer to use the 5GHz one if possible.

Just a follow-up on this.

The issues continue with 2.4G AP also. Almost every time after a reboot it refuses to connect. The only way to make it work is pressing the wi-fi button multiple times until I see ATH: unknown locale: 69 messages in Console, and a line with supported channels of the interface and then it comes back alive.

Any help on the matter is highly appreciated.

I have the same card. Connections do seem to be made a little slow, especially with 5Ghz. I may purchase a BCM card just to compare.

At any rate, nothing you can do... this is just Apple's provided software drivers... I believe a real Mac with the same hardware would have the same issue.

Not true. AR9280 is supported natively.

What needs to be done if I order a HP Broadcom Half BCM943224HMS Wifi 518434-001 802.11abgn?

Patches? Or is it natively supported?

If you followed the sticky guides, it will work.

I got the new card today, and the performance and connection speeds are impressive. I could definitely say now that the Atheros was having some issues. Not sure if it was the card itself or the compatibility with my notebook model.
