-====== Various tips ====== 
  
-===== With maximum output power, I'll get a better range  ===== 
-It's false in most situations.\\ 
-As an advice, in a home environment, the best output power is not everytime the maximum. In most situations, 30mw is enough.\\ 
-If you're doing long links, yes, maximum output power is the best. 
-===== I'll buy amplifiers to have a better range  ===== 
-That's not a very good idea because:  
- 
-  - Amplifier also amplify noise and that's not a good thing for link quality  
-  - With high amplifications, you could get headache  
- 
-Then you should better buy good antenna's 
- 
-===== My card says that I have 20dBm (100mW) but i only have 18dBm, why?  ===== 
-Most cards have 100mW, but 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 a better txpower, i have receive better  ===== 
-That's false, txpower isn't linked with receiving at all. For receiving, you should see receive sensivity of your card  
- 
-===== 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]]
