I use a TL-MR6400 to provide 4g connection for monitoring cameras at a remote location.  However the router regularly changes its connection profile, selecting a default profile which does not match the SIM I am using, and so it cannot connect and I loose connection.  As I am usually remote, there is nothing I can do to fix this until I am next on site, which is a massive pain!

The listed connection profiles are:

- EE (default 1)

- T-Mobile (default 2)

- Asda Mobile (default 3)

I use an EE SIM, and the EE profile works fine.  Periodically, or when rebooting, the router picks the Asda Mobile profile instead.

How can I prevent the router from changing to a different profile than the one I selected? There doesn't seem to be a way to remove the T-Mobile and Asda Mobile profiles either.
