Archer MR400 changing 4G provider by itself
After 10 months of working without problems my Archer MR400 suddenly by itself changes the network provider, from Telenor wich is my provider to Glocalnet, wich means it looses connection to internet. After resetting to Telenor it stays for 2-6 hours and then it changes again and tries to connect to Glocalnet. Any who have experianced this or have any suggestions on how to solve it? When I check firmware is up to date.
