Need join to 13th channel via Airport
Hi, I have problem with my Airport Extreme card to join on WLAN 13th channel (Europe wifi channels 1-13).
My AirPort Extreme Card is "Third-Party Wireless Card" 802.11b/g, chip Broadcom BCM4315 and it supports channels 1,2,3,4,5,6,7,8,9,10,11 only, but I need to join 13th channel. Can somebody help me? I think, I need some modified driver. THANKS! |
Maybe try this:

thanks for reply, but it doesnt resolve my problem. I dont know why...
look at this picture: http://www.imageno.com/thumbs/20100112/7k66ukhfpl7r.jpg |
I could imagine this to be a limitation by Dell to make their prodcut suitable for outer european FCC rules. Does it work using an other OS? If not maybe ask the Dell support?

Where did you obtain the card, the card may not support 13 channels as a hardware limitation, which means that you may have a shot if you can flash new firmware to the card as an update, but that would probably require access to a Windoze box.

Hi, under Windows XP and Windows 7 card supports channels for Europe 1-13, only under MacOSX it doesnt support 13 channels.

Well you need to find a fix or patch then for your problem, but there has to be some way of enabling it, it may require alot of work though, I think if you modified the .kext file it may work, I have modified WIFI .kext files before to work with different device IDs for different revisions.

Weird thing is that my BCM4311 card (non-branded product) which I had orderd from the UK doesn't have this limit - at least not on 10.6.2
(And it's using them same Kernel Extension.) |
Ok, then maby its the card itself, maby a firmware update on the card?

I do not know how to patch or edit the kext.
But, I must edit IO80211Familiy.kext to work my BCM4135 wifi card, because original kext includes these vendors IDs: 4311, 4312, 4313, 4318, 4319, 431a, 4320 etc... and my card ID is 4315 which is not included in original kext, so I simply added this ID to original IO80211Family.kext and now it is working, but only on channels 1-11. |
That means that the device parameters need to be tweaked inside the kext, especially if it works fine under windoze with all 13 channels, This would be intresting to see, I would like to get more than 11 channels too.

Wouldn't it be easier to just change the channel your router/access point broadcasts on?
