It should be due to incompatible wireless encryption methods. You can do the following test:

Create a new Test SSID, uncheck 6GHz, and choose the encryption mode as below:

  @Vincent-TP Still doesn't solve my problem. I create a new SSID at 2.4 GHz with the following settings.

 hi, @Nohwal 

Just noticed that you are not using the latest firmware. You can update it first. You can download the latest firmware from this link:

This issue only happen on Andriod's phone and TV? How about IOS? 

What if create a test SSID without a password?

  @Vincent-TP the issue only happens on Android phone and TVs. The internet works perfectly fine on Windows laptops, iPhone and Macbook. Even on Android devices, it shows they are connected to the SSID but there is no internet.

I have also tried with no security but the problem persists.

The latest firmware on TP-Link India's website for my device is EAP225(US)_V5_1.1.3 Build 20230224 which was published on 14th March 2023. When I try to update the firmware with this version, I get the message that the installed firmware is the same version - so it seems to be up-to-date. Any other pointers you could give please?

Hi  @Nohwal 

That's not the latest firmware.  Please use this link to get the latest firmware: https://www.tp-link.com/us/support/download/eap225/v5/#Firmware

If you are still redirected to India website, you can manually update the URL country code from in to us.

  @Vincent-TP Thanks Vincent. I have now upgraded to the latest firmware version as mentioned by you. So now the things get even murkier from here on. The wifi shows connected, the status shows "No internet" and yet phone has intermittent access to data now. I had made sure to switch off mobile data and any other wifi network in the vicinity. So essentially, the devices now have intermittent access to internet. I have not been able to find a pattern as to when and for how long the connection stays but seems like the mobile now has been able to make an unstable connection with this network now. Any further tips on what could be causing this? Many thanks for your help.
