Hey guys, I recently picked up a DWA-556 Dual Band because I heard it had great compatibility. It detects just fine as native AirPort on my Mountain Lion installation but it doesn't seem to pick up any networks. I assume that because it's detected, I don't need to modify any kexts. So I'm using vanilla Mountain Lion IONetworkingFamily.kext and IO80211Family.kext (does that sound right?).

Here's the system profiler dump:

  Software Versions:
  CoreWLAN: 3.0 (300.9)
  CoreWLANKit: 2.0 (200.10)
  Menu Extra: 8.0 (800.7)
  configd plug-in: 8.0 (800.15)
  System Information: 8.0 (800.1)
  IO80211 Family: 5.0 (500.15)
  WiFi Diagnostics: 1.1 (110.26)
  AirPort Utility: 6.1 (610.31)
  Interfaces:

  Card Type: AirPort Extreme  (0x168C, 0x3A7E)
  Firmware Version: Atheros 9380: 4.0.70.23-P2P

  Locale: Unknown
  Country Code:
  Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, 165
  Wake On Wireless: Supported
  AirDrop: Supported
  Status: Not Associated

Techniques I've tried so far:

1. Set AirPort router channels to 11 and 36 (5GHz)
2. Tape pin 20
3. AtherosFix.kext
4. Custom DSDT (change device label to ARPT, add _DSM method)
5. LegacyAtheros (see http://www.insanelym...dpost&p=1823049 )
6. IOProbeScore 600 -> 500 in AirPortAtheros40.kext
7. Remove OSBundleRequired / Network-Root


Kernel logs show:

AirPort: Link Down on en1. Reason 1 (Unspecified).

I've pretty much run out of ideas at this point--any suggestions?

tape pin 20 is for laptop switch on.

likely u  have to rebrand in dsdt like ar9285 fix. but id 30 not 2A
also someone posted there something about removing Network-root in plist fixed it

that lil blue text at bottom of my last post.

Yeah, thanks I tried a custom DSDT edit (see original post, now edited) without luck and a few of the other suggestions in the thread. Nothing

To solve this problem, Open the info.plist file which is located in the IO80211Family.kext > AirportAtheros40.kext > Contents
and delete the following 2 lines
<key>OSBundleRequired</key>
<string>Network-Root</string>

try older 10.6.8 or 10.7.2 kexts for network
did u do dsdt irq fix ?
have u tried different slot ?

buy a different card.. the adapter from New Mini PCI-E to PCI-E Wireless Adapter + 3 antenna WiFi

Hello,

Have you solve this?

I have the same card and having the same problem too.

I´ll try my best to solve it, but i need help like you.

Thanks.

Hay Chris B,
   This may sound obvious, but is there a wireless switch?    I saw the same behaviour with the AR9285 card my Dell Vostro 3350 running 10.7.4.  The card was detected okay, and would look like it's scanning for networks but the list would always come up empty.  Oddly the wifi enabled light on the laptop doesn't always stay in sync with wifi actually being enabled.  So after a few days of frustration and many different 802.11 kexts I found the solution was just to press Fn+F2 and wait a few seconds. I really kicked myself when I found this and though may I should go a work with animals or take up gardening rather than continue my interest in computers.   I now have WiFi and BlueTooth working.(Although I haven't tested them thoroughly yet.)
   I'd be interested hearing if you find a solution to getting the DWA-556 working, I've recently bought a AR5BHB112 to use in a HP 8760w, and it seems to have the same problem...  It's the same chip I think..

irqs in dsdt need to be removed and the network-root fix in plist

That works?  Or is it a suggestion?

When you say irqs you meet the _PRT Method on the device or something else?

Thanks,
  Tim.
