Cannot get Wifi to connect, always comes up in access point mode

[chris-0xcd]

Question My EMS-ESP doesn't want to connect to my WIFI network. It always starts up in access point mode. My access points show up in the network scanner and I select the one with the best reception. I've tried playing with the network settings but nothing seems to help. The EMS-ESP is only a meter away from the closest access point so I don't think reception is an issue.
Not sure if it makes any difference but I have multiple access points with the same SSID but on different channels to extend the range of the Network. I never had a problem getting other devices to connect.

Any help would be appreciated.

are you using a BBQKees E32 board with ethernet?

[chris-0xcd]

Yes but I don't have an ethernet cable connected. I plan to run a cable eventually but wanted to run it on wifi until I get around to that.

[MichaelDvP]

Reason code 15 is 4way handshake timeout (v3.5.0b10 shows this as text). Maybe the AP does not answer to wrong password (some AP do that as DDOS protection). Do you have different passwords to the APs with same SSID? Depending what APs used, it could help to reboot the APs.

[chris-0xcd]

Thank you for your help! Turns out the 2.4 GHz interface on the closest AP had an old password set. D'oh!
I didn't even realize the passwords for the two interfaces are controlled separately. Would never have checked that without you asking if all APs had the same password. Looks like all my other devices work on 5GHz so I never even noticed.

It works perfectly now, thanks again!
