The thing to keep faith in , is that the TTN gateway does work for a lot of people.
Chances are it is the environment / router rather than a hardware / quality control problem.
It could be that the TTN gateway is vulnerable to noisy environments (Other RF / WiFi instability from router / poor mains filtering), but the existance of working gateways show that it can be made to be OK.
So with that in mind, just thinking of things to try.
Does anyone with an unsuccessful gateway live near someone who has a working gateway?
Someone takes the “unsuccesssful” gateway to the person who has a “successful” gateway, and tries to activate it there?
Obviously, the one who has a working gateway, switches it off while the experimenting is going on. If this works, then maybe leave the gateway there for a few days to see how it performs?
This should help indicate if the gateway does work in a similar environment
My gateways works, so I’m happy to test my environment for others if they are nearby in NW of UK, just PM me .
N.B. I use a guest wifi network on an ASUS router, and the gateway connects fine, but I have had problems with the gateway getting stuck if I switch the gateway on before the router wifi. so I always ensure the correct power on sequence.
I also have the gateway fairly close to the WiFi router?
Is there anyone else in other areas that are willing to voluenteer?
