TL-WR740N does have temperature issues and requires fans especially if it is deployed in a closed box outdoor like on the illustrated picture. Hardware versions up to 3 work pretty hot while v4 stays considerably colder than its predecessors. It is a whole new concept in hardware while v1,2,3 are hardware identical and less good (not to say worse, they all work well but v4 works best of them).
I have this exact problem too.I asked for help a long time ago but noone couldn't help.P.S. I tried all them commands but they didn't work
I have installed openwrt + luci GUI and it is working ok know:
- no problem with client mode
- no problem with setting ap for private network
- NO PROBLEM with custom mac address for client mode
Until there is no new release, I reccommend you to do the same - openwrt.

Of course. So far it has been 4 months since the first build and at the moment most of the bugs are still there.
Openwrt guys take care about them and try to fix and will respond you kindly on the forums, while here I got rude responses most of the time.
Well, I'm not an expert, but you're using an omnidirectionnal antenna, and also this device will output only 18dBm at max power, about 63mW.
With this router and the stock antenna, put in my window (I live in a 4th floor) I can see my network at about 80m (the end of the street) with an RSSI of -70dB, which is ok.
Maybe you can achieve 300-500m if you set the antenna in a high place and it is a clean terrain, but it would be a very poor signal.
So I would forget about that 2KM...
Without using high power antennas both for the router and the clients, you won't be able to get that 2KM, unless you make a link with high gain directional antennas, in that case, it may work.
In the images shown I can see a RSSI between -80 and -90dBm . That is almost the limit within you may connect with a unencrypted network, and with a very slow speed and bad quality signal.
With WPA with signals below -86dBm is almost impossible to establish the connection.
What is the distance between the clients and the router for that signal levels?

No soy un experto, pero este router emite 18dBm como máximo, equivalente a solo 63mW.
Y ademas, estas utilizando una antena omnidireccional, que repate la señal en todas direcciones y recortando aun mas el alcance.
Yo tengo este router pegado en mi ventana, con la antena de serie, y mi red aparece al principio de la calle (a unos 80 metros) con una señal de -70dBm, que no esta mal.
Asi que quizas consigas alcanzar 300-500 metros con mucha suerte colocando la antena alta y en un terreno limpio y liso, pero tendrias una señal muy debil.
Pero de los 2KM de alcance lo dudo mucho.
Sin utilizar antenas de potencia, tanto en los clientes como en el router, es completamente imposible.
A no ser que utilizaras antenas direccionales de mucha ganancia entre el cliente y el router, en ese caso podria conseguirse un enlace punto a punto, pero nada mas.
En las imagenes que has puesto puede verse que los clientes tieen un RSSI de entre -80 y -90dBm, esos niveles son practicamente el limite para poder realizar una conexion, y eso en redes sin encriptar.
Con seguridad WPA, con una señal por debajo de -86dBm es practicamente imposible conectarse.
¿A que distancia estaban los clientes del router para tener esa señal?

Pues, lo dicho... complicado esos 2KM.
Tendras que ponerle un amplificador, o un router de mas potencia, y aun asi dudo que funcione, porque aunque el router emita con mas potencia y asi llegue la señal mas lejos, la mayoria de dispositivos emite 60-100mW, asi que no seran capaces de alcanzar al router.
En ese aspecto es necesario que ambas partes emitan a una potencia similar para que puedan comunicarse entre si.
Ya ves que dd-wrt te muestra una calidad de enlace de solo un 6-14%.
Para que te hagas una idea, consigo unos 18 Mbits reales con una calidad del 50%, y a partir de ahi sube.

HELP!!! where can i download the revert bin file for the WR741ND v1.9?????

The repeater mode doesn't exist in atheros. It's client mode, but adding a virtual interface as AP.
AT first I tried client mode only, and connecting the computer through ethernet to the switch.
As it worked well, I added the virtual interface, as AP, bridged with the client. Worked the same in the ethernet side, and then connecting through wifi and also got great performance.
Do you think there is a difference between hw versions?, according to tp-link the only diference between wr740n v4.x and wr741nd v4.x is the detachable antenna, and also the only diference between subversions (4.x , 4.y, etc) is the firmware (software) version.
I am reading mixed results, as I said, I also have a wr841nd v7.2 (build r17201) and client mode works perfect, but that same build doesn't seem to work for people with hw version 7.1, and I kindda see the same patern here, wr740n v4.2 working ok, but wr741nd v4.3 having issues.
Just got in my new 740n ver 4.22 from Newegg..
To tell you I was a little nervous about getting this working...but a BIG THANKS to devs for the working firmware..
I needed this for getting my Slingbox on my network and it worked without a hicup ...
I am hooked up wirelessly to my Verizon Fios router without changing it to DD-WRT like I've read someone mentioned somewhere..
