Agreed, it's more devise with wider channels and 40 on 2.4 is common. The Netgear app on Android (which isn't as horrible as I thought it might be) decided to tell me the best 2.4ghz channel is 3..... ok it is as horrible
Last year I had a student complaining about wireless in their room, it was their own printer causing issues. Turned wifi off on printer. Everything great, they only used the printer via USB anyway -- Jason Cook Information Technology and Digital Services The University of Adelaide, AUSTRALIA 5005 Ph : +61 8 8313 4800 CRICOS Provider Number 00123M ----------------------------------------------------------- This email message is intended only for the addressee(s) and contains information which may be confidential and/or copyright.

Lee The positive is that you didn't have to argue with a neighbor that tells you that their vendor recommends that one use channels 1-2-3-4-4-5-6-7-8-9-10-11 in 2.4 with 40MHz, something you don't know as a spoiled rich-kid customer of your vendor.... Seriously I do see such devices more and more. Some are dockstations, printers, etc... I must have a trace somewhere...let me dig it out if I can...

Thankfully, we don't have a high volume of rogue access points in our dorms. But... I just saw my first 5 GHz 160 MHz wide flame-throwing problem child. Curiously, the OUI identifies it as a Cisco device. Wide AND loud, for your viewing pleasure. Get enough of these sorts of devices in one building, and 5 GHz will fast become the same cesspool that 2.4 GHz has become, or worse. And as an added bonus, also found a Canon printer that is doing 40 GHz channel width from channel 3 as it's out of box default. Anyone else seeing a new class of problem devices in this regard? -Lee Badman Lee Badman | Network Architect Certified Wireless Network Expert (#200) Information Technology Services 206 Machinery Hall 120 Smith Drive Syracuse, New York 13244 t 315.443.3003 f 315.443.4325 e lhbad...@syr.edu<mailto:lhbad...@syr.edu> w its.syr.edu SYRACUSE UNIVERSITY syr.edu ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
