I bought this: http://www.airlive.c...er<br /><br />S
et the region to south america, and you get a total of 2000mW output,It also has passive POE support. :-)
Added a 9dBi antenna, and I now have coverage beyond my dreams :-)
Edit: should add that the N.power device is 150mbit max, single antenna. All devices requiring more speed a wired.
As for the Trendnet tew-638apb, I had this and the tew-637ap earlier, and both locked up when some specific devices (tried to) connect to it, or even scan for wifi networks.
Firmware on both were up to date. Never did find a solution. Only thing was to ask people to turn of wifi on their phones and then restart the AP.
