Go into the network properties for the adapter and change the 802.11n Channel Width (2.4 GHz) setting from 20 MHz to Auto.Tim, I can easily get a 300 Mbps (channel bonded) connection between my internal Intel 4965AGN laptop client and the Netgear WNDR3700 at 5 Ghz. However, even though I have everything configured the same for 2.4 Ghz band, the maximum link I get is 130 Mbps.
Go into the network properties for the adapter and change the 802.11n Channel Width (2.4 GHz) setting from 20 MHz to Auto.
Unfortunately there is only a Channel Width setting for 5 Ghz, which is already set to Auto. I searched around some more and apparently my internal card (Intel 4965AGN)is only capable of 20 Mhz @ 2.4 Ghz. Intel seems to frown on Channel Bonding on the 2.4 Ghz frequencies, since there are only 3 non-overlapping channels, so I'm not sure if it's a hardware limitation or a software limitation imposed by the driver.
Anybody know the full story?

It took awhile to track this down. But this is not a bug. It turns out that WMM must be enabled in order to guarantee that 802.11n HT (High Throughput) rates (anything above 54 Mbps) are enabled.
I'll be writing up a short article to explain.
Now it's a little testing/trying behind me.
Yesterday I've got the equipment on the Saturn store (sister of Media Markt). I was very happy to get both product in one turn: the WNDR3700 and the WNDA3100.
At my flat I was placing the router exactly to the same place where the DIR-825b1 stand one day before. My main PC has having also the same position.
First I've used the already installed "Fritz!WLAN Stick N" dual-band usb adapter (http://www.avm.de/de/Produkte/FRITZBox/FRITZ_WLAN_USB_Stick_N/index.php).
After the first data moving in both directions and frequencies, I was just stunning about the relative bad performance of the WNDR3700. I was really shocked. Okay, on 2,4 GHz was only a little bit slower than the DIR-825 but in 5 GHz was terrible. Download 5-8 MBit/s and upload around 10 MBit/s finally goes to 20-25 MBit/s.
With the same WLAN-Stick (Fritz) I've had around 40up/50down on 2,4 and 30up/40down on 5 GHz with the DIR-825b1.
Uhhh, hurry up, try it with the Netgear stick too. But no significant change, the 2,4 GHz performance still below of DIR-niveau and on 5 GHz still unusable.
This all means, that for me seems to be better choice the DIR-825 and means NOT that the WNDR3700 would be bad.
I need good download performance on both band to feed my mediaplayers. Strong upload would be nice at least on one of the bands to fill my NAS behind the WLAN router. That's all my criteria.
By the way: the NMT-based mediaplayer can accept the dual-band stick of WNDA3100. This was the second aspect of my test, because nobody could answer me this important question yet. That's the very good news.
Q: How can I recognize which revision has my WNDA3100 stick?
From here I know v1 has Atheros and v2 has Broadcom chipset in it, but where/how is it signed on the stick?
Thanks in advance,

P.S.: A little question at the end: how should I set my internet conncetion, when I will using two WLAN networks on the same PC? My PC is connceted via PCI-card G-adapter from US Robotics to my WLAN-modem (internet). When I start to use the second WLAN adpater to log into the another WLAN where my NAS is, my internet conncetion goes wrong. How can I drive two WLAN sticks (logged in into two networks) on my single PC?
thats exactly what I thought, thanks!Mixed N and "legacy" clients (802.11a, b, g) simultaneously active only on the same radio cause performance degradation.
