I finally received my new ALFA and i am very happy with the results.(I have said months ago that i would buy but didnt

Before
==

usb wlan: TPLINK 422G (v1,v2) + TPLINK tl ant2414 yagi 14dbi ====> 2 APS: Neigboor's WIFI PSYCHEDELIC (-82-84 dbm) 2 bars

AFTER
==

usb wlan: ALFA AWUS036H 1 WATT + TPLINK tl ant2414 yagi 14dbi ====> 6 APS: Neigboor's WIFI PSYCHEDELIC (-51,-53 dbm)!!! 5 full bars

...so i am very happy with that small beast I ordered from data-alliance.net official retailer and i suggest taht site than ebay.

MY QUESTION IS
===================

I used default settings with tx power 1% in WINDOWS7 - last drivers from alfa website.

In Windows XP the POWER CONTROL DRIVER works together with normal driver or i need to unistall NORMAL first...(so is standalone)?

I will have tomorrow XP-OS so for now i can't test.That's the reason of my question.
