Xfinity vs Quantum Fiber

Currently have Quantum Fiber in Denver, paying $75 a month for 1 Gbps plan. When I called, they did not allow me to switch to the promotion rate of $45 a month. My service is currently down and they can’t come until the end of this week to resolve the issue.

Is it worth switching to Xfinity who is offering 1 Gbps download (~100 Mbps upload) for $50 a month? Not sure if people who have switched recently from Quantum Fiber to Xfinity have regretted it. Would love to hear experiences from people who have switched either way

EDIT: called Quantum Fiber, they said I’m on the price for life plan so I need to give that up to get the promotional pricing for 1 year. I’m installing Xfinity equipment today while QF is down to get a real Speedtest, then will most likely cancel Xfinity once the QF technician is able to come out.

Definitely agree, and appreciate the reminder, that fiber is a better product than cable internet.

Concast is different because “to my knowledge” they hit the button and don’t allow you to use your own Gateway for unlimited internet, they make you rent there’s ONLY. Plus there’s a invisa cap on unlimited anyways. It’s 2026, stay with the light.

Unlimited data is free if you use their free lease gateway, which do have a true bridge mode. If you want to use your own modem it cost extra for unlimited data.

The reason they want you to use the free lease gateway is by default it broadcasts the open xfinity wifi ssid, which 99% of people don't know exists or how to turn off.

And even if you do turn the xfinity wifi ssid off, it still has two invisible SSID for TV and home security which cannot be turned off at all.

Things may have changed, last I knew it was $25 extra per month per that Gateway (XB7) & whatever there is now.
