Sorry...when Mike migrated to the new forum format, the old forum links went dead.
http://www.ubnt.com/forum/viewtopic.php?p=42475 DEAD LINK, but here it is.
When using 12 volts:
Some people have experienced problems with as little as 150 feet run of CAT5.
Most people experience problems past 200 feet with CAT5.
Some people say the thicker gauge CAT6 works. But personally I believe when using the thicker CAT6, the decreased voltage drop will be so small they may not be a significant advantage after you compare the cost of CAT6 versus replacing the 12 volt power supply with a 24 volt one.
Most people run an 18 or 24 volt adapter as a solution.
With the exception of the Bullets' 24 volt max input voltage, all the other radios are 25 volts.
Many people have successfully tested long term use of 24 volts on the Bullet using a good quality power supply.
Almost all wall wart power supplies are switching power supplies now, very rarely will see an analog voltage regulator scheme. That means you have to very very careful when working at the max voltage levels of a device, because a switcher only begins to regulate after it sees the load. That means it can potentially output more than 24 volts for a very brief moment immediately after power is supply to the switchers input.

Use AirControl; now it should be quick :D
I'm very interested! I would love to find out more inforamtion related to this topic. Thanks in advance.
me too, I need more detailed info :icon_twisted:
