![]() * lenovo portátil a menos de 100mts con una pared de obstáculo * debajo del nodo en mi la casa con un nokia c3. It should be flashed directly to chip using SPI programmer. Here is a full flash dump of 4MB flash of this router (TL-WR740N HW rev 4.2) which was used to recover "dead" router. ❺ que distancia estaban los clientes del router para tener esa señal? Sin utilizar antenas de potencia, tanto en los clientes como en el router, es completamente imposible.Ī 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.Įn 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.Ĭon seguridad WPA, con una señal por debajo de -86dBm es practicamente imposible conectarse. Pero de los 2KM de alcance lo dudo mucho. 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.Īsi 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. Y ademas, estas utilizando una antena omnidireccional, que repate la señal en todas direcciones y recortando aun mas el alcance. No soy un experto, pero este router emite 18dBm como máximo, equivalente a solo 63mW. What is the distance between the clients and the router for that signal levels? With WPA with signals below -86dBm is almost impossible to establish the connection. That is almost the limit within you may connect with a unencrypted network, and with a very slow speed and bad quality signal. In the images shown I can see a RSSI between -80 and -90dBm. 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. 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. 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. ![]() 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. ![]() Service Tor Fail Release 03/19/12 (SVN revision: 18777) He says that hardware comes at a range of 2km to 5km. Location: Lincoln, Buenos Aires, ArgentinaĮs: Una duda que se origino con un colega radioaficionado yĮl dice que ese hardware llega a un alcance de 2km a 5km.Įn: One question that originated with a fellow ham and ![]() 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. So far it has been 4 months since the first build and at the moment most of the bugs are still there. Until there is no new release, I reccommend you to do the same - openwrt. NO PROBLEM with custom mac address for client mode no problem with setting ap for private network I have installed openwrt + luci GUI and it is working ok know: ![]() I tried all them commands but they didn't work I have this exact problem too.I asked for help a long time ago but noone couldn't help.P.S. ![]()
