Just because they can set their fantasy levels doesn't mean that the hardware is actually transmitting that powerful.
There are also several changes in txpower handling between 10.03.1 and current trunk, then there are varying EEPROMs in the wild, different configurations (user regd on and off) and finally multiple hardware revisions.
Topic: How to set txpower above 17db on WNDR3700v2 with Backfire 10.03 RC5
The content of this topic has been archived between 31 Mar 2018 and 11 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.
So what you mean is that we shouldn't bother about getting more than 17dB since the hardware do not support it?
Exactly.
11g OFDM on 2.4 GHz ~ avg. 17 dBm peak power per chain (report 15 C, pg. 66+)
11a OFDM on 5.7 GHz ~ avg. 19 dBm peak power per chain (report 15 C, pg. 168+)
One other small item to consider, this is two way communication, the other end (ie. laptop or computer) would also require improvment in signal strength.
Better antenna and relocation of the router and laptop is an optimum solution.

I am still stuck
I have an WNDR-4300 and it is stuck at the following:
wlan1 IEEE 802.11an Mode:Master Tx-Power=14 dBm
RTS thr:off Fragment thr:off
Power Management:off
wlan0 IEEE 802.11bgn Mode:Master Tx-Power=19 dBm
RTS thr:off Fragment thr:off
Power Management:off
and I cannot get it any higher.
The stock firmware offers a lot of more range and stability for the wifi link (at great distances).

try this and read the readme before !
ok, did the patch and it seems to work for the 2.4GHz wifi when I set the reg domain to US but the 5GHz radio is still limited to 14dBm even with the patch applied and iw list listing all channels unlimited...
and since the 5GHz range is most concerning this is just a very limited fix so far... but thx a lot for the quick answer
The discussion might have continued from here.
