Have you tried to enable Smart Connect?  Are you using a network name and password you used on a previous router?  If so the client devices may think they are connecting to that device and give the invaild password as a result.  You can also try this Beta Frimware.  http://support.tp-link.com/f/3ba5085b7c/?dl=1  Designed to address a issue with in Homecare but might also help with your concern,  not sure if it will or not because this is a unique issue but new FW often optimizes other services as well.  I'd start with Smart Connect and go from there.

 

Let us know

i tried to turn on the smart connect but no luck note that i have turned off the wifi SSID from the ISP modem so i only have the C5400X wifi band on since i bought it and set it up few months ago which was working fine, i also tried updating the beta firmware but no luck also still same error incorrect password and unable to join.

@a7mdoff 

 

Ok, we need to determine if the issue is hardware or software.  Try switching your wireless to an Open, unsecured network (testing only) and then see if devices can connect.  Also try to connect to a guest network as they are seperate radios.  Let us know the results.

 

thank you

I don't reconize them as an authorized retailer so to be safe i would return through them.  They may be a VAR through a distrubitor but that would be a different porcess and I'd hate to see you have a delay in the return/exhange process.
