Does anyone know why there is such a big radio transmit power difference between OpenWRT and DD-WRT? On OpenWRT's 2.4GHZ radio I get 26db of TX. On DD-WRT no matter how much I fiddle with the settings it never goes above 16db. I get higher TX power with Panama but it breaks connections with some Apple devices.
I have been able to achieve 24dBm on 2.4ghz using Canada (I can stay at 28dBm on 5ghz (wlan2) much longer). It doesn't last forever. 3-4 days max before I need to reboot. Before I changed to performance cpu governor, I was only getting about 12 hours, so while this helped, it didn't resolve the issue long term.
How did you go about setting the governor to performance? thanks!
I cannot, for the life of me, no matter what region+channel I use on wlan0, get anything above 17dbm.

Add this to Administration/Commands/Startup:
Code:
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] || continue; echo -n performance > $CPUFREQ; done
You can choose the CPU frequency from the Administration tab. I am presently at 1920mhz without any issues. If you choose to overclock it, KEEP AN EYE ON YOUR TEMPERATURES for a few days.

Using Canada domain, wlan0 seems to be limited to 17dBm. I can mostly maintain 24dBm on wlan1 however and 28dBm on wlan2 but after about 6 days now, the power drops on wlan1 to 16dBm. With that said, this does not hold up on another test mx4300 which even with the same exact settings, I cannot obtain the same outputs.

It is interesting CPU frequency could change the wifi output power. Is it due to the chip temperature is running high?
Is it possible to insert some log into the code when wifi power changes? I will volunteer myself help collecting logs.

According to @BrainSlayer, it doesn't. I just posted from the results I was seeing. I cannot explain why or how. It is what it is...

I have not been able to log anything related to the power drop. I keep 8 logs via logrotate and nothing ever gets reported. These routers are weird. I have four and I cannot make them all behave the same with the (mostly) exact same settings.
EDIT: Something to note. Both wlan1 and wlan2 seem to work much better with wlan0 turned off. Why? I have no idea! _________________ - Linksys EA8500: I-Gateway, WAP/VAP 5ghz only. Features: WDS-AP, VLANs, Samba, WG, Entware - r59429
