I´ve been trying for a full day this devices A3 and de AP/Route are unable to work in WISP way with out being pluged to the original modem by a ethernet cable, even the instructions indicate tha you can repeat signal fron wirelles signals, the device are unable to get it and repeat it wirelless, even that in instructions of Tenda site http://www.tendacn.com/tendacn/Support/show.aspx?articleid=715 indicates wan mediom settings, in the ap/routter this option does not exist, so far Im thinking about going and buy a long ethernet cable to stop figthing with the second anthena that does not take singnal and repat it at all

This product is no even able to reboot itself properly after configuration, maybe after 20 or 30 time you try it will reboot and that does not ensure that it will work wireless always Ethernet cable behind.
