Hello,

I upgraded my firmware from 1.2.3 to 1.3.1 yesterday, since then, my fiber connection (2gb//1gb) connected to the SFP+/WAN gives me a speed of 10mb/0.6mb. I tested my ONT directly on an external box and it works correctly. No settings have been changed on my router between before and after the update. Is there a way to downgrade the version? I tried but it failed
