Model: AX55 Pro V2/ Build: 1.0.5 Build 20240121 rel.56156(5553)

During routine network operations, the TP-Link Archer AX55 Pro router encountered a login loop on the web management interface when login through LAN static IP. Specifically:

• The administrator enters the correct password,

• The system appears to authenticate, but immediately redirects back to the login page,

• No error message regarding incorrect credentials is displayed,

• The issue persists across multiple browsers and workstations.

This behavior prevents access to the management dashboard, creating operational risks as configuration changes and administrative tasks cannot be performed.

Troubleshooting Performed

• ✔ Switched browsers (Chrome → Edge → Firefox): issue persists

• ✔ Cleared browser cache, cookies, and sessions: no improvement

• ✔ Rebooted the router: issue reoccurred

• ✔ Tested using Incognito/Private mode: still unable to log in

• ✔ Login with wrong password: the system still detected

•
