Airpot Extreme with xFinity Internet?

I have an AirPort Extreme I would like to use as my "customer owned third-party modem/router" with xFinity internet - does anyone know if that is possible?

Bridging Wi-Fi to Ethernet, post Airport Extreme I ditched my Airport Extreme because Apple stopped supporting it. What steps can I take to accomplish bridging between my new Wi-Fi network and the home ethernet network? (Airport Extreme accomplished this by default.)

Connecting Airport Express to non-Apple router to extend network: need bridge mode? Our internet is out for a while so the neighbor is letting us use their wifi, but the signal is very weak. I could run ethernet from their router to an Airport express in my house, but would that cause problems with their network? Would they need to change settings on their router to bridge mode, for example? I don't want to put them to that much trouble.

Pros / Cons of setting up a 5GHz network in Airport Utility Wireless Option The Question: My all-AirPort Extreme network works fine (Xfinity, ~300mbps down, 25mbps up on an "Up to 800mbps" plan). Might using 5GHz lanes help get more WiFi speed? The Setup: My cable internet comes in through a Motorola MB7621 modem and is router'ed into the house by a latest generation AirPort Extreme ('mothership'). Two other AirPort Extremes are Bridged to the mothership via Ethernet and set to create their own networks of same name and credentials. There is another AirPort Extreme in the house that is set to 'extend' the network wirelessly (I wanted to ethernet it in but can't get a cable to that room, darn it). Using the default setup (e.g. not modifying Wireless Options) I can get around 300mbps wifi download speed anywhere in the house. This is generally fine. I recently had to replace the mothership device with a new-to-me unit ('mothership II', eBay, $44!) and now I am wondering about whether creating and selecting discrete 5GHz networks could help my WiFi speed, and if yes is there anything else I have to do to see improvement? Spoiler: I tried it - specifically checking the 5GHz box in the 3 AirPort Extremes that are creating their own networks then restarting the whole system, including the modem. No apparent speed change (still between 315-333Mbps down, 25Mbps up). My operating theory: My inclination is to customize as little as possible while milking every bit of bandwidth out of my ancient gear. My reasoning for sticking with this ancient gear is that it works and I understand it so in the few-and-far-between times that it doesn't work, the AirPort Utility and its ever-present approachability is there for me in a way I can remember and/or intuit quickly and without needing to find a manual, a forum, or vendor tech support. In other words, if it ain't broke, don't go buy really cool but so overkill Ubiquiti gear or the 'that seems like it would almost do for $400 what my current setup does for free (and without the Google/Amazon privacy tax)' mesh networking solutions. That said, it would be cool to figure out a way to eek out all the speed my beloved AirPort gear can give me. I suspect it's mostly about the "extend my network" device dragging speeds down, but I don't know and figure you guys might. :-) Thanks in advance for any insights.

15+ years on this support forum and I have no idea what a "customer owned third-party modem/router" might be or what it might do.

For what it's worth though......the Airport Extreme is not a modem/router, so that might answer part of the question up front.

What kind of service would a "customer owned third-party modem/router" provide to you? What would it allow you to do that you cannot do now?

"customer owned third-party modem/router" is the term xFinity uses for a combination modem/wifi router (or separate modem and wifi router, for that matter) owned by the customer and not provided by them.

But you have answered my question, as what I really need is a modem...thank you!

The AirPort Extreme would work if you have a simple modem........the kind that has only one Ethernet port.
