Hello
I have RB 750GL and it’s been working fine for the last three months. Suddenly it caused a problem and the router gives upload speed 50 kb instead of 400 kb in the past. I tried to reset the router but no change. I tried to restore old settings, but also no change. And when I remove the router and connect to the fiber line directly, the speed is fine. I bought another device from the same model and installed configuration on it, but the same problem occurred. I tried to use another old backup, but nothing happened.
Could you please help me?
