@Lindr_ZA Deco E4 does'nt support WPA3. I think you are using WPA/WPA2 and you have to use only WPA2

@David-TP Can you provide him Bangladesh customized firmware.

@ChrisMac You can try this beta firmware 1.4.0 from the link below. 👇 https://community.tp-link.com/en/home/forum/topic/856648?moduleId=39

@ImtiazAli No.....It's official stable not beta.

@Panman81 I think you are using an older version of Deco App because the signal bars color is now dark green. First of all update your Deco App because sometime app shows wrong icons and info.

@ImtiazAli 3.10.176 now
