Cannot connect the Wifi on Macbook Air (Invalid Password)

Model : TL-WPA4220KIT
Hardware Version :
Firmware Version : 3.0.3 Build 20171011 Rel.42507
ISP :
Hardware Version: V3
I have found that some users have reported the same issue. Tried all of those solutions but still in vain.
Here is the problem encountered:
When I use the Macbook Air to connect the Wifi, it keeps prompting the error message "Invalid Password".
But I am 100% sure the password is correct and it happens only on the Macbook Air, I can connect the Wifi using iPhone, iPad and Android devices.
I have tried the hard reset, downgrade the firmware, upgrade again but still in vain.
So I tried to set the Security to "No Security" and without the WEP/WPA/WPA2 password required it works like a charm, however... yes you know, not practical at all.
I am suspecting there might be an encode, encrypt/decrypt issue when my Macbook Air and WPA4220 are connecting.
Ultimately, I had hard-reset the extender and use the default SSID and password provided by the user manual to check if there are any hints, but still cannot connect while other devices work as a charm.
Thanks in advance!
PS: I can access the root router without any issue.

Mid 2011, High Sierra version 10.13.3

Got the same problem on Macbook Pro Mid 2010. Changing to TKIP has not solved my problem. Anyone has got a better idea?
Hmm, I was to quick. Now it really DOES connect, after I changed the encryption to TKIP. I'll be watching it. Thanks anyway!

This thread is a life saver! Same issue, phones connecting to new tplink network, Mac would not with "invalid password" message. Switched network security settings as described to TKIP and Mac was able to connect.

Invalid password Solved for macbookpro 2011

Ive just found out and that solved for my macbook pro.Go to ip address that is assigned to your wpa4220 (not your main router). It might be something like 192.168.1.x (x mine was 12), default password might be admin, password admin if didnt have changed it yet.Then go to wireless->configuration->advanced, and just change encryption from “auto” to “TKIP”’and thats all. Save configuration and try login with your password. I think that macbookpro late 2011 have some issues with “AES” and when i changed to TKIP, it works for me.Hope that helps others...tp001 wrote
I don't think anyone with this issue has his/her problem solved. Yet, no TP-LINK admin tried to investigate this issue as I know.
Thanksss. Worked for me

Essa solução funcionou perfeitamente para o meu MacBook Pro 2011 com o Mac OS High Sierra. Basta alterar nas configurações avançadas, a criptografia de “AUTO” para "TKIP" e ... veja ... conexão Wi-Fi estável!
