@Arpi28 Do you have any Windows PC connected to the AX3000? If yes, then check whether the TP-Share media server shows up and is accessible from Windows File Explorer under "This PC". It is indicated...

@BenjiThatFoxGuy Hi, Would you mind telling us the name of the mobile carrier? Could you please show us how you have populated the fields In the "Create Profile" menu?

@AB-Abdullah21 Is TL-WR845N the router model you are searching updates for? Then just go to TP-Link's support webpage directly. https://www.tp-link.com/en/support/download/tl-wr845n/

@IAIB Is there any chance that computer might be running some sort of third-party "Privacy Protection" or "Anti Spy" software, which could be changing the MAC address?
