I purchased a TP-Link A55 and set it up yesterday as a secondary access point, connected via Ethernet to my main router. It worked fine at first. Today, it completely stopped working.

 

I tried the following steps:

 

  • Power cycled the device
  • Disconnected and reconnected the Ethernet cable
  • Rebooted the router
  • Verified the main router and Ethernet cable are working (tested with my old router, which works fine)

 

 

The TP-Link A55 shows no connectivity, and I cannot access its admin page. It appears to have failed after less than 24 hours of use.

 

Please advise on next steps or replacement options.

Hello @Mabr ,

Welcome to our community.

 

Please check the model of your router:

How to find the model number of your TP-Link device 

How to find the hardware version on a TP-Link device

 

If you set the router back to wireless router mode, can it work normally? Please try:

    1. Make sure the main router's Internet works fine by using a PC wired to the same port of the router to have a test.
    2. Replace the cable connecting the A55 and the main router.
    3. Switch to a different LAN port on the main router.
    4. Reset and reconfigure the access point(A55).
