I must say it's quite disappointing that the A9 lacks support of n-networks 🙁

With the insane requirement to network stability when using Airplay, it's almost impossible to understand why they only implemented b/g.Considering the price point, it's a no-brainer.

The 2.4 Ghz spectrum is really crowded 😭

I've just moved my A9 onto a 2nd WiFi network and it works great. Before the A9 my router was only using Wireless-n but when I introduced the A9 it switched to both 'n' and 'g'. This was the cause of some of my problems which also slowed all my other devices.

How did B&O release a product using older technology?

I'd like to send the A9 back and wait for the upgraded A9 with Wireless n and optical input. I suspect they rushed this to market thereby upsetting many customers and destroying the reputation of such an iconic brand. Pity because the A9 had such potential.

I connected the a9 via cat6 a week ago hoping this would solve the disturbing cracking noises  (like static discharge) maybe in the wireless signal but no result. it's less but still there. Even when receiving sound from TV via RCA.

i think only thing left  is to send it back unless anyone found a solution for this

To be fair, the antenna in the A9 is pretty good. Most of the problems in playback is caused by my iPhone 5. But my A9 is also placed close to my router.

BUT the A9 is the only b/g only unit I have on my network, which forces me to have a b/g network active. This means a poorer range and higher risk of interference from neighboring networks.

For an instance, inSSID gives my b/g network a "link rating" of 30 at best. This rating depends on signal strength and other networks on the same channel. My n network on the other hand have a perfect 100 score. 

The problem with b/g is not the bandwidth, it's the overpopulated channels which decreases the range and stability of the network.   

I love my A9 and after some intense network setup the connection is stable, but not withouts faults. If I had the opportunity to use a n network does stability issues would be non-existing.

The A9 is still a killer product, but the price justifies top notch technology!

but all modern wireless routers can operate on b, g  or n simultaniously and having a g-device present should not slow down n-devices.

my wirless router is just a few meters away from the a9 before switching to cat6 and even then when checking th wireless signal in the beoplay app it said marginal..

so why if you play via iphone 5 trough airport extreme wireless (all N devices) to the a9 connected to this airport extreme via cat 6 is the sting still unstable ?? do i need to start watching star trek to look for solutions  

Plugging in a product that is marketed as WIRELESS is just wrong.

I have no problem operating b/g and n devices simultaneously on my network. My router can handle that without any problem. But it doesn't change the fact that the A9 could be positioned much more freely if connected as a n-device. Because of the massive interference on 2.4 Ghz bandwidths the A9 needs to be relatively close to the router to have a strong enough signal.

You cannot change the fact that n-network has a much higher capacity and range. I would expect such a protocol to be included in a premium product.

Don't get me wrong, the A9 does what it says on the package. My problem is that it would do it a lot better if it had the newest technology.

Airplay is a technology with lofty goals and potentially spectacular results that just doesn't seem fully baked and kind of sucks in the end. I agree that Bluetooth's bandwidth is not sufficient for top quality audio but I sure experience less dropouts and easier connections when using it on some of my equipment. In fact, I have a product in my BATHROOM (yes I like to have music in there) called a SoundFreaq which is a cheap Bluetooth compatible iPod dock and radio with surprisingly good sound quality. I can have music playing in my bathroom, take my iPhone out of the bathroom with me when I'm done in there, and walk all the way into the living room without any dropout from the Bluetooth signal. As bluetooth is only advertised to work best at 30 or 40 feet I'm not sure how this is possible through a wall and easily 75 or 80 feet away but it does work.

I can also confirm that I have an AT&T branded 2Wire wireless router and in order to solve a lot of my Airplay problems (to my AppleTV, I don't own an A9 or any BeoPlay product) I had to force the router to use N only. When it was allowed to run in compatibility mode for older wireless devices the performance of Airplay was significantly degraded. And even now, I find that in the late afternoon I get Airplay dropouts. I'm going to try connecting the Apple TV via ethernet straight to the router when I get a chance in order to eliminate at least one point of failure, but these things should really work as advertised and I find it interesting all of the people who say that Airplay worked much better in iOS5.

That said, Airplay from my Retina MacBook Pro won't behave any better when the iPhone is cutting out. So it's probably just a general congestion issue on my end.

I can not WAIT for the Wireless Speaker and Audio (WiSA) technology to be implemented by B&O and others.

Just learned that the lack of wireless n support is caused by the Airplay chip, as this does not support it. The chip is supplied by an Apple manufacturer.
