-====== Various tips ======
-===== With maximum output power, I'll get a better range  =====
-This is a false assumption in most situations.
-In a home environment, the best output power is not always the maximum. In most situations, 30mw is enough.  However, if you are a long distance from the AP, then yes, maximum output power is the best.
-===== I'll buy amplifiers to have a better range  =====
-That is not a very good idea because:
-  - Amplifiers also amplify noise and that's not a good thing for link quality
-  - With high amplifications, you could get a headache
-You are much better off purchasing a good antenna with high gain.
-===== My card says that I have 20dBm (100mW) but i only have 18dBm, why?  =====
-Most cards have 100mW when combined with the antenna (2dBi antenna).
-In 802.11a and 802.11g, the output power is 30mW due to modulation (it's a bit harder to use [[http://en.wikipedia.org/wiki/OFDM|OFDM]] than [[http://en.wikipedia.org/wiki/CCK|CCK]])
-===== With better txpower, I will have better reception  =====
-That's false, txpower isn't linked with receiving at all.  For receiving, you should see receive sensitivity of your card.  As well, you are much better off purchasing a good antenna with high gain.
-===== Which antenna to choose  =====
-You should see [[http://www.macwireless.com/html/help/antenna.html|Antenna help]], Selecting a [[http://www.radiolabs.com/Articles/wifi-antenna.html|Wifi Antenna]] and [[http://netstumbler.org/showthread.php?t=2751&page=1|Netstumbler forum]].
