subharmonic reset button is supposed to wipe the device to defaults and back to original firmware. Unfortunately though the reset button does almost nothing, because the DPR team decided for some reason to keep all the routing settings and keep the wallet binded even after a reset.
DPR should make the reset button actually wipe the device including the routing and wallet bound to the device, because if you have physical access to the device you likely own the device... And if someone stole it and reset it, they would lose access to your funds.
At least for now we must put up with the reset the way it is, until they properly fix the reset code.
As for the light blinking until you plug second wire in, this is how it is supposed to work. If there is no one (device) to pass the internet to, why pass the internet or even waste power? So the device will shut down unless there is a computer or router using it. If the ethernet cable is unplugged and replugged, you will have to wait for the device to reconnect to the tunnels again.
The 34.34.34.34 page only comes up when the device is powered on and active. To be active, it needs a internet connection, and it needs at least one computer or router connected to it. Once it has those, it will connect and the light will change to green. Once the light is green, you should be able to access 34.34.34.34
If you ever lose connection, the 34.34.34.34 page will not show up.
If it is your first run, you need to give the device 15-20 minutes for it to update itself and connect. Once the first run is completed, it is a bit faster to connect. Just grab a coffee and check back 30 minutes later, it should be working by then.
Unfortunately as the device is in working condition I don't think you can return it... Simply not understanding how to use the device is not sufficient reason to receive a refund. If the device was actually defective, that would be understandable, but it sounds like the issue is technical knowledge or lack thereof. The other problem is that Kickstarter TOS states that you are donating to the campaign and receiving the pledges are not guaranteed.
Just read the manual word for word and you should have a better understanding of the device. - https://deeper-network-inc.gitbook.io/deeper-connect-knowledge-base/
