Hi:

I’ve got a couple of RV50s mounted on buoys in Ireland. They have Three.ie SIMs in them. The RV50s are constantly connecting and disconnecting (say, every 2-3 minutes). Can someone have a look at the log output below and let me know if they can see why? Thanks

Hi,

Can you check the Signal Strength (RSSI) before and after disconnecting from the network?  
As I see that you used open.internet.public APN. Do you need a public IP ?  
You can try using open.internet APN ( private IP) instead of open.internet.public APN.  
Please check your SIM card account with mobile operator.

> Hi Recently I cannot get my dongle to connect to the open.internet.public APN. I have used this for years as I need a public IP, but it's not working now.  Can you please check that whatever needs to be configured on the account from your side...
