If you want to register for warranty purpose, you can just keep the invoice.

Packaging says Regsiter at uk.tp-link.com/support to register and get an extra year guarantee
but nothing obvious on the page.
Only a link to a page about returning products under guarantee............ :-(:mad:

Just bought a product from Amazon and tried to register for the 3 Year Warrantly. Website ( https://warranty.uk-tp-link.com) is dead. Alas there is no need to register for the 3rd year...

"Thank you very much for selecting TP-Link products. In order to provide our customer with a better warranty service, TP-Link UK now offers a 3 Year Warranty program on our selected SOHO Products. The prior version of the 2+1 Year warranty policy has been cancelled and no longer valid. In other words, the warranty period will be automatically upgraded to 3 years, and you will no longer be required to register products on our website as soon as your SOHO Product is purchased."

Exactly same problem.

How can we register to get full 3 years warranty as advertised?

If you buy the tplink in UK, don't need to register any more. " the warranty period will be automatically upgraded to 3 years, and you will no longer be required to register products on our website as soon as your SOHO Product is purchased". Just keep your receipt.
