@2309 Hello, I just bought a Tapo RV30 too and having the same issue.
Tried everything with my ISP router, from channels to custom DNS IP address (only 2.4 GHz).

 

But the device do connect to the router, and I can access it locally, so it must be a WAN issue.

The fun fact is, I have several Tapo devices reaching the Internet from my LAN.
So it's a Tapo RV30 issue, for sure.

 

Digging in my home network, I found no issue concerning the DNS forwarding.
I have a local Raspberry Pi and Pi-Hole on it, the FQDNs are translated AND not blocked from/to my RV30.

 

Can TP-Link provide us a status on this ?

Thank you for your assistance.

@2309 I'm having this same issue! Not able to connect to my Wi-Fi network. I also bought the item from JB-Hi Fi. Interesting! 

 

Have you been able to conenct yet?

Bonjour Nathan, Je pense que tu es francophone comme moi ! Pour ma part le SAV de TP-LINK m'a fait réaliser un diagnostic à distance et il s'est averé que mon produit était simplement défectueux. Il m'ont proposé de le leur retourner pour réparation, mais j'ai préféré en demander le remplacement chez Amazon, où je l'avais acheté. Bon courage !

I got mine from JB today and cannot connect. I’m so angry!

Hi Sarah, 

mine had to reboxed and sent back to the warehouse for replacement. It took a few weeks. If you picked it up at JB, maybe take it back there and get them to swap it. If they couriered it to you, you'll need co call tplink and get them to arrange the courier. 
I was told it was an issue with the networking chip, they wanted to repair it, I asked for a whole new device. 
good luck.
