Does customer support exist for TP LInk? Chat doesnt work and phone gets put on hold indefinitely. Registering my products doesnt work either as the tool claims my serial numbers are not valid.
Anyway - I have 4 TL-PA9020P and one is failing to connect to the other 3. It worked for a few months but now is unable to be seen by the TP Link utility and no longer will sync with the other units. What can be done to RMA these things?
