Have you entered correct login and password for service no-ip? Do you have latest firmware? My suggestion please disable UPnP service on the router.

Yes, I've verified the login and password is correct. The firmware is also the latest.

I've disabled UPnP service on the router, still no joy.

Yes I've verified that the login and password is correct and it is running the latest firmware.

I have disabled UPnP but it still doesn't update automatically.

I've tested the same with a DDWRT router and it works fine sadly that's not compatible with ADSL service unless I have a bridge.

Do you have public IP address on the router from your internet provider?

Yes I do.

managed to telnet into the router, still doesn't update DDNS when dhcp expires after 24 hours.

DDNS - restart - Iface not found

Sorry I don't have any more ideas in this issue.

I'm having the same issue with the exact same situation. One thing that's really odd, is when I set up no-ip and saved the information, after I click on "login" I see a message stating "dyndns". I suspect that the router's software is not using the correct DNS provider that is saved; instead it is using the first or default one for dyndns. If someone else can replicate this issue then I suspect it's a router bug and it will need to be fixed with the next firmware update.

I'm having the exact same issue. DDNS is not working for my no-ip.com option. I've verified the id/pwd work from the no-ip.com website and my PC's DDNS client. When I try to login via the TPLINK admin screen I briefly see the message "dyndns" instead of my no-ip.com selection. I suspect this is a bug and if I'm correct it will have to be fixed and distributed in an upcoming firmware update.

What is your hardware version of your TP-Link?
