Setting up an xfinity access point

I just signed up for xfinity internet (no cable/TV) and I've got this modem, an Arris TM602G/CT that I found in the dumpster at my apartment complex -- someone was moving and threw it out along with a few monitors and desktop towers. It still works, I can connect to it with an ethernet cable. A neighbor has an xfinity access point nearby but the signal is sketchy, though I'm able to login with my own account and use it. How would I go about setting up my own xfinity access point using this modem? Do I need a special modem and/or router?

I've yet to see anyone make that work as an AP.

You've made some progress but let xfinitry support configure it the first time to work with your system.

Update (Solved)

Just an update- turned out to be pretty simple. Just connected an ethernet cable from the modem to my laptop and the coax from the wall into the modem, went to and it went through the process of configuring my modem.
