If you’re used to FIOS, Xfinity might be frustrating. There are technical limitations to Xfinity’s speed. FIOS’ connection is the same bandwidth both ways: uploads are as fast as downloads. Xfinity is a different story - the connection is asynchronous – upload speeds are less than 10% of download speeds. What that means is I can hear and see my colleagues on Teams calls but I often appear blurry or the sound cuts out to them, especially if I’m on WiFi. If you do have to use Xfinity, it’s best to be on a wired connection - it’s better but not perfect. I wish I could go back to FIOS but I no longer live in Pittsburgh and Comcast has a contract with my county to be the sole provider of tv and internet service here.

Comcast was ok when I knew a tech there. Great to call him from time to time without the wait! My FIOS internet has worked great after I moved. Xfinity sends me a zillion mailing to get me to switch but that ain't going to happen anytime soon.

If it works fine wired, but not on wi-fi, then your wi-fi signal is the problem, not asynchronous upload bandwidth.

Don't get me wrong, the 10% upload is atrocious, but not the culprit in this case.

The last comcast 2-in-one modem I saw at a neighbors was a piece of crap. No external antenna's, signal wouldn't cover a 2 bedroom ranch. PSA - and this may be out of date - you should be able to buy your own modem and router and it will pay off in a year vs "leasing" their crap equipment for a fee every month.
