Model: RE505X  
Hardware Version: V2
Firmware Version: 1.1.0 Build 20241224 Rel. 35085

I am using a TP-Link AX1500 device in Access Point (AP) mode, connected via LAN cable to my main router (IP: 192.168.1.1, DHCP enabled).

  • In AP mode with LAN connection, devices that connect to the TP-Link Wi-Fi get disconnected after some time.

  • In extender mode (without LAN), Wi-Fi works fine without disconnections.

  • It seems to be related to a possible IP/DHCP conflict when the LAN cable is connected.

Request:
Please investigate this issue and provide a fix or recommended configuration for stable connectivity in AP mode with LAN backhaul.

Device details:

  • Model: TP-Link AX1500 (https://www.amazon.in/dp/B0859M6P2C?ref=ppx_yo2ov_dt_b_fed_asin_title)

  • Hardware Version: RE505X v2.0

  • Software Version: 1.1.0 Build 20241224 Rel. 35085

    Please find the attached log for reference.

Re:Connectivity issue with TP-Link AX1500 in Access Point mode-Solution

Hi @asishpmathew ,

Welcome to our community.

 

If you want to set the extender to be an Access Point, you only need to change the operation mode:

  • Click Mode in the top right corner of the page.
  • Select Access Point and click Save. The extender will reboot and switch to Access Point mode.

 

Please try the following suggestions:

1. Test the internet connection by connecting your client devices directly to the main router. This will help determine if it is specific to the RE505X or if it's a problem with the router itself.
2. Try using a different port or cable to connect the main router.
