Has anyone suggested to students that only have single-band wireless adapters to obtain a dual-band USB adapter for better performance (by driving them to the 5ghz band)?  If so, have you seen adapters that you would not recommend in an enterprise environment?  We have a Cisco wireless infrastructure and have been testing the Cisco/Linksys AE3000 and newer AE6000 USB adapters.  No real feedback from students yet, but am looking for other viable options to recommend if they exist.

 

Background:

We have one residence hall that is half student housing and half HUD senior housing.  We own the building, but can’t take full occupancy until some date in the future (2018 maybe).  Due to leasing agreements and such, we don’t have students all on the same floors (students and seniors are intermixed on every floor).  This building is all wireless and has about 7 APs per floor.  We believe that due to the AP density and the possibility that there is personal wireless (in the senior housing apartments)  in close proximity to our infrastructure, we could be dealing with a great deal of interference in the 2.4 Ghz band.  Roughly 53% of all wireless devices on campus are running 802.11n on 2.4 Ghz.  Almost every student that has called to complain about a poor wireless experience in this hall is using the 2.4 Ghz band.  Hence the desire to provide options to our students with single-band adapters to purchase something that is a dual band.

 

Thanks,

I suggested a USB adapter for the first time yesterday! An expensive alternative to asking your neighbor to turn off their bleating HP printer...but that was the option chosen.

You might want to survey the area to verify your hypothesis. My guess would be that you have more 18 year old printers and routers than 70 year old routers. If you do end up with a lot of hip grannies I might consider carving out a "Free Senior Wireless--complements of Moody" SSID and just give them free internet access to rid yourself of the problem. If you hunt gramps' routers down you can mark them as known rogues and let your auto-RF channel assignment do it's job and plan around them.

At UMass Amherst we use USB Dual band Adapters to help diagnose wireless issues for students on campus. If they only have a single band adapter we lend them a Linksys AE2500 dual band and see if that helps. I’m not sure on the actual numbers, but switching from a single band to a dual band adapter does solve a large number of problems for students.

 

We have also used Linksys WUSB600N adapters before and those also worked well. As long as the adapter is wi-fi certified and dual band it seems to work reasonably well here.

 

I'm just shocked that in 2013 there are still computers (laptops) shipping with single-band WiFi adapters. Apple's been shipping dual-band since the introduction of the MacBook in 2006, and included "n" in late 2006.

While there is nothing that you can do about it now, perhaps your new-student information on technology should stipulate "purchase with dual-band wifi" - or, tell them to purchase a Mac! ;)

Message from pmauretti@massasoit.mass.edu

Much like with USB3.0 and the number of computers that came out without it, or with only one or two ports out of six, it all comes down to cost to the computer manufacturer.  Most consumers aren’t savvy enough to know the difference, but they do know the difference in seeing a lower price between two laptops, even if it’s small. 

 

But believe me, you’re preaching to the choir about this. 

 

I like this page that Drexel has…
