I have several hundred routers running OpenWrt kamikaze 7.09. When I check their transmit power with iwlist, it shows up as 32 dBm. This can't possibly be correct, can it? I've found all sorts of things regarding users wishing to INCREASE their transmit power. How can I decrease the power if it really is 32 dBm?
Also, these routers are mobile. Is there any way to detect wireless interference? Can I scan for other APs in the area and change channels? If so, does this disrupt active clients?
Hi.
Install the proprietary "wl" utility with ipkg, it provides various commands that are useful when working with the broadcom driver,
Regarding the 32dBm you're right, the value reported by iwconfig is just nonesense, use "wl txpwr" to see the actual values.
Example from my Wrt here:
root@bridge-wrt54g:~# wl txpwr
pwr in mw 72
pwr in mw after override adj 72
