 6LoWPAN ND and Thread use IPv6 for connectivity. Therefore, you need to verify first that you have a working IPv6 connection. To do that, ping the Connector IPv6 address `2607:f0d0:2601:52::20` from your network.
 
+**NOTE:** If you are using  [k64f-border-router](https://github.com/ARMmbed/k64f-border-router) (which can be used only as a 6LoWPAN BR and only with FRDM-K64F), you need to enable another security feature. By default, k64f-border-router uses `PSK` as security. You can either enable security here on your mbed-os-example-client application, e.g.,
+
+```json
+    "target_overrides": {
+        "*": {
+            "mbed-mesh-api.6lowpan-nd-security-mode": "PSK",
+        }
+	}
+```
+or you can remove link layer security from k64f-border-router. For doing that, change the [mbed_app.json](https://github.com/ARMmbed/k64f-border-router/blob/master/mbed_app.json) fetched from k64f-border-router repository, e.g., 
+
+```json
+    "config": {
+            "security-mode": "NONE",
+        }
+```
 #### mbed gateway
 
 To connect the example application in 6LoWPAN ND or Thread mode to Connector, you need to set up an mbed 6LoWPAN gateway router as follows:
