High-speed Wi-Fi with Xfinity at 5Gbps using a 80MHz bandwidth channel
You were checking Xfinity’s Wi-Fi settings and noticed a discrepancy in channel widths—your router uses 80MHz while your AP shows 40MHz. It’s not unusual for routers to default to different channel sizes, but matching them can improve performance. Consider adjusting your router to align with the AP’s configuration if possible.
80MHz boosts data transfer rates and overall speed, though if you're near the Ubiquity AP it may be better to reduce it to 40MHz to minimize interference.
The signal should be adjusted to 40MHz if you're aiming for that distance.

The MHZ refers to the portion of the wireless band you're using. This chart shows the spectrum for 2.4 GHz. The blue curve represents the SSID's coverage, which affects how much bandwidth it uses. For instance, a signal on channel 6 at 20 MHz will spill into channels 4, 5, 7, and 8. If it were 40 MHz, it would cover twice as much. The one you mentioned operates at 80 MHz, which is quite powerful (the 5 GHz range is broader). Lurick's comments about AP and router proximity suggest that if they're near each other, the AP might occupy a large chunk of the 5 GHz spectrum, potentially causing interference with your router's signals. Use a free Wi-Fi analyzer app to check for interference in your area, and consider switching the AP's channel if you notice issues.
