Internet Dropping Intermittently

Hello, I'm having intermittent internet issues that started about a month ago. I'm using an Arris SB8200 modem with my xfinity service. I work remotely so I am aware of outages during business hours. The modem is about a month old and I must reboot the modem to get the internet working again. I have spoken with customer service. I live in an apartment building and am not able to replace any splitters or lines.

Hardware: Arris SB8200
Both wired and wireless network.
