Testing over 2.4ghz? 

5ghz?

Wired? 

How are you testing? What device? What band? 

Those are all key as 2.4ghz is a slow network and 100mbps is about right. Not for wired or 5ghz

Are the speed drops happening only over Wi-Fi as well?

If the issue occurs on both Wi-Fi and wired connections, we recommend checking the cable signal levels within the gateway. If the signal levels are out of the acceptable range, they can lead to the kind of connectivity issues you're experiencing.

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:

https://arris.my.salesforce-sites.com/consumers/articles/knowledge/G34-G36-Cable-Signal-Levels

The cable signal levels displayed on the interface page reflect the signals being transmitted by your Internet Service Provider (ISP).

If you notice that these signal levels are outside the recommended range, we suggest contacting your ISP to have them reviewed and adjusted accordingly.

While ISPs may have their own approved signal ranges, for this gateway to function properly, the signal levels must align with the acceptable values outlined in the reference article provided.

@Dfulton I’d encourage you to start your own post/thread so your details don’t get confused with the OP’s post and details.
