WZR-HP-G300NH 1.3.10 Tx Power Setting

[xlphobialx]

I have a Buffalo WZR-HP-G300NH router with the 1.3.10 Gargoyle firmware. I was taking a look at the setting for increasing your transmit power. The issue is I want to set it to around 27-29dbm but cant since the range is limited to 0-20. I don't understand this because in OpenWrt you can set it to 27dbm and beyond. I know from smallnetbuilder.com that this router can push out 29dbm. My question is, does the older 1.3.5 fw have a broader range and if not is there any way to increase this setting?

As Eric wrote in an other post

Code: Select all

....
When the channel is the max, it automatically gets set to use htc40-, otherwise htc40+. 

If you will force the wireless always use channel width 40 MHz, add the option 'noscan' equal 1 in the wireless config file.

About the Tx Power its depended which channel you use in 5 GHz range. With US as regdomain and channel from 149 you can gain max. output (30), lower max. (17)

excuse my ignorance, but where to enter "cfg80211: Regulatory domain changed to country: US" ??

You don't need it, just sysinfo by running Putty; dmesg. What I want to tell you is the Tx power is depended which channel you do use with the set of regdomain, ex. US, Canada or Europe

List of WLAN channels

Try this: ssh to router using whatever you choose. Putty, terminal, etc.

Type: iwlist txpower
Look at wlan0. This will show current txpower setting.

Type: iwconfig wlan0 txpower 27
This will change the txpower setting to 27dBm (501mW)

Confirm with iwlist txpower
Should now show wlan0 with increased txpower.

Hope this helps.
