(or have you pumped it up in a power-increasing section on GUI?) It's quite important to me whether it works when powered by OpenWrt because I am going to buy the device due to, among other things, the high power, which is even suggested by manufacturer's long 5dBi aerials.
But, going back to the point, could you explain in detail how and where exactly you have fix the problem with WLAN?
My fix is "manual fix". As you have seen, there are no answers on forum so far.
I have checked with iwconfig what actual values are.
root@OpenWrt:~# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
eth1 no wireless extensions.
br-lan no wireless extensions.
wlan0 IEEE 802.11bgn Mode:Master Frequency:2.432 GHz Tx-Power=27 dBm
RTS thr:off Fragment thr:off
Power Management:off
mon.wlan0 IEEE 802.11bgn Mode:Monitor Tx-Power=27 dBm
RTS thr:off Fragment thr:off
Power Management:off
root@OpenWrt:~# iwlist txpower
lo no transmit-power information.
eth0 no transmit-power information.
eth1 no transmit-power information.
br-lan no transmit-power information.
wlan0 unknown transmit-power information.
Current Tx-Power=27 dBm (501 mW)
mon.wlan0 unknown transmit-power information.
Current Tx-Power=27 dBm (501 mW)
wlan0 unknown transmit-power information. -> is very strange and confusing.
Than I just entered 27 to web interface.
By the way, I can confirm that signal from WR841ND is very strong.
Antennas are standard WR841ND - same which were in the box when I bought it.
They look well done and solid - better than antenna from my ASUS WL-500G Premium v1.
And antenna on ASUS is better than non-detachable antennas on Linksys WRT54GL
