BE550 - login problem (sometimes)
Time to time I have a problem logging in to my Archer BE550.
The web UI shows “Operation Failed” during login.
Everything else seems to work normally; only router management/login is affected.
If I use the Tether app during this time, I can log in to the Archer, but none of the options/actions work.
After rebooting the router, everything works again.
Any ideas where I should look for the cause of the problem?
Yes, I have already done a factory reset.

How do you access the router's WebGUI - on its default iP address http://192.168.0.1 or http://tplinkwifi.net ?
This could happen when your device is not connected to the router's wireless SSID. Is there any other wireless devices in your network except your BE550 ?
You can troubleshoot this case scenario by issuing a continuous ping in the CMD: ping 192.168.0.1 -t (given that your router uses it's default LAN IP address).
Use a laptop when you doing the troubleshooting test. If you are using a wired connection to your router, that should not be the case and the issue is elsewhere.

@terziyski Access via IP. Login page is ok, but proper password won't let me in. I'm wired to router.
Everything is working beside accesing the router. As I said - Tether app log me in, but functions aren't working.

- Clear Browser Cache: Old cached data frequently causes Web UI conflicts. Clear your browser’s cache and cookies, or try using an Incognito/Private window.
- Disable Secure DNS: Built-in secure DNS/DNS over HTTPS in modern browsers (like Chrome or Firefox) can disrupt local router domain access. Temporarily disable this feature in your browser's privacy settings.
- Check Device IP Address: Instead of using the domain (e.g.,
tplinkwifi.net), log in directly using your router’s local gateway IP address (usually192.168.0.1). - The BE550 V2 continuously monitors connected devices to build dynamic network topology maps. If you have dozens of smart home or IoT devices, this process rapidly eats up the router’s cache memory.
- Go to the HomeShield tab.
- Turn off Device IoT Security scanning or real-time traffic statistics. Removing this intensive tracking stops the logging processes from crashing the web daemon.
- If nothing helps so far:
- Update Firmware: Go to the Advanced or System settings inside the Web UI and check for any firmware updates, as TP-Link periodically releases patches to address background process bugs.(check this thread).

@terziyski after router reboot everything is working again.
I tried:
- 3 different machines
- clearing cache
- private tab
Under HomeShield tab I have only QoS enabled.
Got 22 clients connected. 6 of them is small IoTs.
Firmware is up to date.
