Motorola Modem Not Taking New Boot File And Internet Speed Stuck at 30 MBPS instead of 400 MBPS

I have a Motorola MG7540 modem, and even though I’m on a 400 Mbps plan, I consistently get no more than about 30 Mbps at home. Today, a technician informed me that my router isn’t receiving the new boot file and is stuck on an older “silver” boot file, which is causing the speed issue. Unfortunately, he wasn’t able to provide a solution.

I’m requesting your help to resolve this problem. I’m paying for a 400 Mbps plan, but my speed remains stuck at around 30 Mbps.
