Hi Pete, They do not do 3x3. I don't know of any adapters that do besides the Intel 5300.
I haven't done any extensive throughput testing with those adapters. In terms of actual, real-world use though, they are performing fine. We have a few dozen people using them without issues.

What is the best up/down throughput that has been achieved on them with channel bonding?

The USB is really only for the few desktops that some students bring in. We sell it (the WUSB600n) at our bookstore. The PCMCIA one is the Linksys WPC600n, and we use it for some older laptops that don't have any wireless or only have 11b.

Whish ones did you choose? What about desktop computers? Do you provide any solution for wireless? There do not seem to be any dual band 11n desktop cards. You can buy adapters and use some of the laptop cards, though.

We push the 5 GHz as much as possible. Between the microwaves, Xbox 360 controllers, Bluetooth, and everything else, the 2.4 GHz in the dorms is a tad unpredictable. We sell dual-band 11n adapters in our bookstore, educate helpdesk visitors, and I am always testing how things look in the field. The great majority of the time, things work perfectly fine. When it doesn't, I will typically work directly with students to figure out why. Flipping some adapters to prefer 5 GHz (or only use 5 GHz even), or even suggesting that the microwave not be sitting 6 inches from a laptop typically takes care of things :) Matt Barber Network Analyst Morrisville State College 315-684-6053 -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:wireless-...@listserv.educause.edu] On Behalf Of Hector J Rios Sent: Friday, April 24, 2009 7:19 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Wireless-only in residence halls I forgot to mention that as well. In almost all of the rooms that we went into when we were doing our surveys we saw a microwave oven and an occasional 2.4GHz cordless phone. We spoke to Res Life and explained to them the impact that such devices could have on the wireless network. Having a dual solution is great because the 5GHz band is less crowded. But unfortunately many wireless adapters tend to prefer the 2.4GHz band. Disabling the 2.4GHz would be wonderful, but the reality is that there are still a lot of legacy devices out there, so you have to support them. We even considered offering 2.4GHz at 2Mbps only, hoping that this would discourage users from using 2.4GHz altogether and opt for 5GHz. The issue here is how to get users to adjust settings on their end so that they only use 5GHz. Currently we have opted to attempt to "educate" our users on how wireless works, how certain devices can have detrimental effects on the network, and how small modifications to their adapter settings can make a huge difference. Utopian, I know. I'll let you guys how that idea goes.
