Xfinity 5ghz Wifi using 80Mhz channel width

[AlanAlan]

I was scrolling through the xfinity wifi setting and I saw that the 5Ghz network was using a 80Mhz channel width. Is that normal? On my ubiquiti ap I have 5Ghz on 40Mhz. Should I change my xfinity router to match the channel widths of my access point?

80MHz enables faster AC speeds and peak performance but depending on how close it is to the Ubiquity AP you might want to drop it to 40MHz for less interference.

The distance is about 50ft away. Should I drop it to 40Mhz?

I think he meant close as far as what channels each network is on.

The MHZ is how much of the wireless channel band you take up


This is the spectrum for 2.4. The blue dome (for lack of a better word) is how much that SSID would take. So for example that one is on channel 6 but is 20mhz, so bleeds into 4, 5, 7 and 8. If it were 40mhz, it would take double.
The one that you have mentioned is 80mhz, so is freaking massive (The 5ghz spectrum is much longer however). What Lurick meant about how close the AP and the router is that if they're very close then your AP is taking up a lot of the 5ghz spectrum which may cause interference with what your router is kicking out (if they're on the same channel)

Try a free wifi analyzer app and see what it can see in the air, if it is interfering a lot with other 5ghz broadcasts then maybe change what channel the AP is broadcasting on.

Yeah its normal. Are you having problems? If not dont bother changing it.
