Hey guys,

I was wondering if anyone knew whether it was possible to set up the new airport extreme (the one with n) to work as both an 802.11a and 802.11g access point at the same time. upon semi-casual inspection it seems it only supports n+a on 5 ghz or n+g on 2.4 ghz, not any combination that has a and g at the same time.

anyone know if this is possible?

thanks!

Hey Albert, i don't think "G" is 5GHz, where as A and N are. As far as i know B and G are 2.4GHz.

So not sure it's going to happen with A/N and B/G combination of any kind working on either's Freq.

802.11g is NOT in the 5GHz band-it's strictly 2.4GHz. 802.11a is entirely in the 5GHz band. 802.11n(draft) can be in either.

Considering the hardware complications of running two different microwave radio systems inside any small piece of hardware, I don't think dual 5/2.4GHz operation is going to be a reality for a long time.

No. The AirPort card in the original MacBooks and MacBook Pros is B/G only.

Except that according to the FCC regulatory statements in the back of the original MacBook manual (available for download from Apple's support site), it specifically says this:

Hereby, Apple Computer, Inc., declares that this 802.11a/b/g Mini-PCIe card is in compliance with the essential requirements and other relevant provisions of Directive 1999/5/EC.

They didn't advertise this capability, but it was there. Several online articles also attest to this.

Well after reading the post above, went to test the MB to see if it would connect to the "N" wireless...no luck

I'll be damned! I'll definitely have to look into this very carefully! I should note that my AirPort card's profile says nothing about 802.11a, only b/g. I wonder how this card could be enabled for the a band...

It's my understanding that it was not, in fact, documented that the Airport Extreme card in the Core Duo MBs and MBPs had the 802.11a capability. But supposedly they do link right up to an 'a' network.

[ghporter]

That card's FCC ID crosses to a FOUR BAND (a/b/g/n) product. It is indeed A capable, but Apple didn't choose to include that capability in the equipment data.

I have a NetGear "A" 5GHz that i'll try it on, i'll let you know what i find out...
