We are using supercannel lisence on rb333 w/3.0rc9 but I do not get the point at tx power tab I’m using xr5 and it’s 28dbm card but I can not set this card to work at 28dbm when i try it’s like 28(18) how can i fix this and router says you can set either -30 or 30 dbm ok but I can understand 0 to 30 but -30 to 0 I don’t get the point. Pls some one discrible to me.
Default is 17dbm and works in 90% of situations. Set it higher and your card might become too warm and thus reducing lifespan.
Use better antenna’s if you want better connectivity.
“This is done to overcome the limitations of using the Linux based drivers for Atheros. They have a maximum power of 18dBm, so we program a +10dB offset into the cards. This will net you full power when using the MadWiFi.”
