In my country, the seller is responsible for the legal warranty, not the manufacturer.

Did you contact the seller?

  @yves_b Here in USA a Manufacturers Warranty is usually supported by the Manufacturer, sometimes for high end products you have to go through the distributor like our fireplace. But if I have a cell phone, TV, router or appliance issue we call teh manufacture for support and service. 

We bought these routers from Amazon - but it was fulfilled by one of their partners. These are USA based products, not grey market. Most resellers by from a distributor, meaning TP-Link sells to a distributur lke CDW, then CDW's clients resell to clients like me. CDW clients (resellers) are usually not certified or authorized direct sellers of the brands like TP-Link - they jsut place orders via the distributor. 

For TP-Link to require consumers to know this - and then to have to fight to get what TP-Link has told us is a defective product - is ridiculous. The product was registered on TP-Link system the day it was purchased, it is under warranty - and now they are forcing clients to fight for what they they paid for and delay resolution.

Bad business.
