I'm becoming disillusioned. The fact that tech support at Eero and Traeger has not figured this out shows that neither is concerned with how this affects their businesses. I bought a Silverton 620 at my local Costco, and like everyone in this thread, I have had the same issues. I've been on the phone with both tech supports and have gone through all of their suggested attempts without success. I've had absolutely zero issues with my Eero Pro 6 mesh network since installing. I currently have forty-plus devices connected to it. A large number of them being 2.4 GHz only devices. Ranging from Nest to no-name Chinese knockoffs that all work without issues. Here is my experience with the Silverton 620
1) Purchased and tried to set up on primary 5GHz mesh. Grill finds network connects, checks connection, connects to the internet, fails with the "Could not get time in reasonable time error."
2)Disabled 5GHz in Eero network through the |Settings|Troubleshooting|My device won't connect setting. Same thing this includes multiple restarts, both grill, and network. Trying installation with QR code and manually.
3) Setting up Guest network on Eero, disabling 5GHz and restarting the network, and installing through the Guest network. Same error. I've also tried installation from Ipad and not iPhone with the same issues.
4) Traeger supports suggest sending out a new controller board. I received the board a week later installed, and I have the same error.
5) I would like to try adding an old router to the existing network to see if I can connect that way but should I or you be required to do this. I've been trying to rid my place of old computer trash during the pandemic.
6) You would think that this would not be that big of a problem to fix if you had the correct people looking at it. I don't know how much Traeger spent sending out the new controller nor what it will cost when I return this to Costco.
7) Don't get me wrong, I really like the grill, and I know I can use it manually, but that's not what I paid for.
8) I see a reference to putting your phone in Airplane mode. How can you set up the grill when you're not connected to wifi, cellular, or Bluetooth?
I guess I'm hoping either Eero or Traeger sees this and decides they should actually address the problem.
