Alternative POE injector for Ubiquiti wireless gear
We have several point-to-point wireless links on our campus using Ubiquiti Bullet wireless access points. These use a non-standard 24 V POE injector to power them. Less than a year after the install, almost all our POE injectors died. We've been RMAing them, but it takes a long time and now the RMA units are dying on me after just a few weeks. Has anyone found a replacement injector from another company to use with the Ubiquiti Bullets? Thanks, Nathan Nathan P.

Re: [WIRELESS-LAN] Alternative POE injector for Ubiquiti wireless gear
A quick check on Amazon shows they list for a mere $17 each: http://www.amazon.com/Ubiquiti-POE-24-Power-Over-Ethernet/dp/B004EFHN66/ref=sr_1_8?ie=UTF8qid=1311170318sr=8-8 At that price, your solution might just be to get a stock of them so you can switch them out quickly, and keep RMAing them. Do that enough and the company will get tired of fixing them and find a way to get you good stuff.

RE: [WIRELESS-LAN] Alternative POE injector for Ubiquiti wireless gear
When I first investigated Ubiquiti they did not have POE readily available. I have been using Laird POE18I injector successfully they also have a POE24i model. I mostly have used with the Ubiquiti bullets. Be aware that some of the Ubiquity products do not tolerate voltages above 24V even slightly. That is why I used the 18V.

ATT WiFi
Anyone have experience with the ATT WiFi product? Upper management is looking into it here. My understanding is they will use our existing Aruba infrastructure to propagate the signal. Curious for input from others on direct experience and technical considerations (in general and as relates to Aruba specifically).

Active Directory authentication for loaned out laptops over wireless
All, Our library signs out XP laptops for student use. These laptops are set for authenticate as computer when computer information is available and should reauthenticate with the user's credentials once they log into the machine. However, we've had frequent complaints that AD is not reachable over wireless, rendering the laptop unusable (it's a loaned laptop that has not been used previously by the user and thus does not have any cached credentials). If the machine is shelved for 10 minutes or so and rebooted, it seems to clear the problem. Our library is a very dense and challenging area to cover with wireless, and while there is adequate area coverage, there are density issues that are no doubt present. That being said, I'm not convinced that this is entirely a wireless problem, but more a Windows/AD problem with a wireless component to it. Does anyone have any experience with this type of situation and could offer some advice?

Re: [WIRELESS-LAN] ATT WiFi
It's ATT overlaying their SSID on top of your existing WiFi infrastructure. A number of schools have done this, particularly those with large non-affiliates visiting performing arts centers and other large venues. Consider looking at your WiFi investment as a giant rooftop in prime location. As such, it has value to them; don't let them try to convince you otherwise. Don't get too greedy, but don't give it away either. -d On Wed, Jul 20, 2011 at 4:51 PM, Williams, Owen otwi...@ilstu.edu wrote: Is this is ATT 3G Microcell product or something else?
