Could you please share the details of your subscribed internet speed plan?
To help isolate the issue, please connect the modem directly to your device using an Ethernet cable and monitor the connection to see if it continues to drop.
If the issue persists, I recommend checking the cable signal levels within the modem. Signal levels that fall outside the acceptable range can often lead to speed drops and connectivity issues.
Cable signal levels are like the volume and clarity of a conversation between your modem and your internet provider. If the signal is too weak or too strong, it can cause communication issues—just like it would be hard to hear someone whispering from far away or shouting too loudly in your ear.
When the signal levels are within the recommended range, your modem can maintain a stable, high-quality connection to the internet
Please refer to the link below for instructions on how to check your cable signal levels:

If you find that the signal levels are not within the recommended range, we suggest contacting your Internet Service Provider (ISP) to have them reviewed and adjusted as needed.
