@davidmu88 hi to what AP are you connecting, for example if you connect to an ubiquiti AP that has air max enable then the tp link won't be able to connect to that access point

i know you are suppose to use your own country but if you can see your country, you can select another country as long as they operate on the saem channels

you can't select a country that uses a channel that is prohibited in your country

i think the problem is the access point not the client

sometimes if you have the access point in 20mhz the client will not see the AP

you should set you channel to to 20/40 meaning both or auto 

try to connect to another access point just to run a quick test

but i think the problem has to be a configuration on the AP

also if you updated the firmware then you reinstall the right firmware

but if you don't do a full restore on the device, you might still have some invalid settings

restore the client and set ip up again

i'm sure that might help

i do connect to other AP but for to avoid any compability issues

is always better to use the AP of the same brand or probably the same device

i known about cases where i can't connect to certain device because they use an incompatible firmware

or simply you have to select the right settings

like only N or B,G,N

the encrypstion setting is also important, some devices don't see wep depending on the mode you selected

use wpa2 and choose the right mode

soemtimes people try to use bridge when they really don't need to

and if the AP can bridge with client then you won't be able to select the device to connect to it

choose the right mode like client

i'm sure is a setting problem , full restore the device

upgrading and not restoring the device will keep the same settings

The one I currently have is the one I specified in the first post, and I downloaded it from here:https://www.tp-link.com/es/support/download/cpe710/#Firmware
and the version that I get the region option is this: https://www.tp-link.com/us/support/download/cpe710/#Firmware

My problem is not so much the version, but when updating the region option disappeared, so I cannot choose my country and I do not see the frequencies that I need to connect, my version of cpe710 is UN, I verified it in the feed. Even if I rewrite any UN firmware version, the region option still does not appear, I also perform factory reset, before and after writing new firmware.

@Fae yes, Argentina, my email davidmu2006@yahoo.com.ar
