Hi guys, I have configured my Kerlink iStation gateway as described in the documentaion. It is also registered on the things stack. The packet forwarder runs with the global\_conf.json of the things stack. ![image](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/8/d/8d9a82cea30e855f766a2c485af8b3a97ec32895.png) In the log the uplinks are also acknowledged. ![image](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/4/2/42b4292527f79537533f1be81e1e3533a07cda61.png) However, the gateway is still not connected to the things stack and I don’t know what the problem could be. ---

I thought it was connected because i changed the server addresse In lorafwd.toml under gwmp the node to “eu1.cloud.thethings.network” and the port for uplink and downlink to 1700. As described in the documentation. What else do I have to change ? ---

So you’ve not seen any hard evidence that you are connected - nothing in the logs of the gateway or on the v3 console? ---

No, i have not. In the Overview of the things stack is the gateway still disconnected. ![image](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/c/a/ca1b21cd0f86e81501d769991ec9d34dbab5ccd6.png) ---

Have you entered the serv\_gw\_key correctly ? > “serv\_gw\_key”: “NNSXS.blah.blah” This should match your _Gateway Link_ API key that you generated Just a thought. ---

Do you know where i can enter this key (in which file)? sorry i am not a professional. ---

On my system I added the key value to local\_conf.json - the file is in the same folder that you downloaded global\_conf.json ---

I cant find any file like local\_conf.json ---

ok, the serv\_gw\_key value can go into global\_conf.json if you don’t have a local\_conf.json But I think the idea is that the local\_conf will override the values that have been created in global\_conf.json (assuming you clicked the download global\_conf button). Normally you would put the personal stuff in there (like “contact\_email” : “value”) and perhaps key values related to gps (assuming you have gps enable to provide better timing). It is also important in the global\_conf.json to adjust the “antenna\_gain” to match the published dBi gain of your antenna (allowing for a few db loss in the cabling, depending on the length and quality of coax between antenna and gateway). ---

Sorry I am a little confused. I have now downloaded the globa\_conf.json as here: [https://www.thethingsindustries.com/docs/gateways/semtech-udp-packet-forwarder/](https://www.thethingsindustries.com/docs/gateways/semtech-udp-packet-forwarder/) Now I have to put in the file /etc/default/lorad at CONFIFURATION\_FILE the globa\_conf.json I just downloaded right ? P.S. when I downloaded again, only globa\_conf.json was downloaded in the folder I just had open. But not local\_conf.json ---

You aren’t going to get a local\_conf.json file from a button that says global\_conf.json. But you don’t need one as long as you remember that you have edited the global\_conf.json by putting in the serv\_gw\_key with the API key to suit and restart the gateway. ---

Is it important in which line I put the serv\_gw\_key here? ![image](https://www.thethingsnetwork.org/forum/uploads/default/original/3X/2/1/21f86d0ec8bd898948522ffdca98964d36998eab.png) ---

Next to gateway\_ID? Pick one and try it, if that doesn’t work, try the other, if that doesn’t work, try both. Please do not post pictures of things that can be copied & pasted. ---

unfortunately still does not work. So I have done: 1. downloaded global\_conf.json 2. added “serv\_gw\_key”: “API Key” to global\_con.json (in all three combinations) 3. put global\_conf.json into /etc/default/lorad 4. enabled the packet forwarder in /etc/default/lorafwd 5. edited lorafwd.toml (node = eu1.cloud.thethings.network and for down- and uplink port 1700) did i miss something or made a mistake ? ---

When you say “API Key”, you have actually put an API key in there? The start `NNSXS.` Did you power cycle the whole gateway each time? ---

Yes, i copied the API from the consle. And yes, I rebooted the gateway a few times. ---

Can you **copy & paste** the global\_conf.json section with removal of some of the letters in the API Keys, just so another set of eye balls can have a look see. ---
