HP Printers / WiFi Direct
We seem to be having more and more wireless interference from devices that are not wireless routers/APs. HP printers and their obnoxious setup wireless are becoming more common, and this semester we've seen a few devices using WiFi Direct (basically an ad-hoc wireless network) - the PS4 has the ability to connect to other Sony devices, and Roku players that used WiFi for its remote control. This forks from the FCC just declared WLAN quarantine features illegal thread, but how are you dealing with these other forms of wireless interference. We've essentially had to resort back to physically locating them and knocking on doors. We printed up an information sheet to slide under doors, and communicate with residential staff, but it seems to have mediocre success. We've also tried to communicate to students that the cause of slow wireless is most likely interference from other devices in an attempt to utilize peer pressure as well. Unfortunately it seems to all be very time consuming to track down and communcate. Thomas Carter Network and Operations Manager Austin College 903-813-2564

Thanks. Kinda funny, I took a beating on Reddit for this. See http://www.reddit.com/r/wireless/comments/2htize/wifi_as_we_know_it_is_doomed/ to be amused. I think you’re either faced with these issues- trying to juggle a lot of complicating factors and still delivering Wi-Fi that works and won’t land you in the headlines as the next data breach- or you’re not.

Re: [WIRELESS-LAN] HP Printers / WiFi Direct
As with others, we're pretty much stuck in a combination of awareness campaigns followed by a foxhunt and knocking on doors. Personally, I think one of the few things that can be done to save what's left of the 2.4 band is to start putting pressure on the wifi alliance to withhold certificate from any device acting as an AP (actual APs, hotspots, printers, etc) if it defaults to transmitting on anything other than 1, 6, 11 (or the equivalent in other regulatory domains). I know it wouldn't be much, but it would at least make a statement. Non-standard channels cause ridiculous performance drops, and I've caught too many home printers and carrier provided hotspots doing it. I had half a greek house getting dial-up class speeds due to nothing more than an HP printer that was happily blaring out its beacons at max power on channel 4, all while the front panel swore up and down that wifi was disabled. It's far from a perfect fix. It's not like the wifi alliance has the power to pull product off shelves, and there will always be misinformed users who don't understand channel overlap, to say nothing of how many crappy devices area already out on the market. But damnitall, at least it would be doing *something* to push back on these crappy default configurations.

RE: [WIRELESS-LAN] HP Printers / WiFi Direct
Well, your article ties in nicely to an idea I floated a couple of months ago that didn’t get many comments from the group… Educause needs to have a Higher-Ed Constituency group held at least one a year with the major manufacturers in which highed-ed gets to bring up bugs and technical issues with the consumer grade crap that is making its way onto our highly designed enterprise networks. I sent an email directly to Diana Oblinger. She politely and promptly responded, saying she was going to pass this onto the head of corporate relations, and I haven’t heard back. It has been a month.

Re: [WIRELESS-LAN] HP Printers / WiFi Direct
This is a great presentation. I think we would be lucky for students to get good performance while sitting still. Not even to mention roaming. :) One bit of good news: we are seeing clients move to 5 GHz more and more. Our band interference issues will hopefully fade out more quickly than we may have initially expected. More and more devices have 5 GHz radios; once all the iPhone users move to newer devices (iPhone 5), that will take a huge chunk out of our 2 GHz users. I can't wait!
