Hub Wi-Fi channels

What Wi-Fi channels are support by the Hub?

Wifi 5Ghz smart connect no good seems to say 1-14

I ask because I have been unable to have the Hub connect to a channel above 11.

I remember David or someone saying that WF will connect to any 2.4 GHZ wifi channel in the world, making the assumption that the wireless access point it is connecting to is operating on legal frequencies in that particular locale.

By not supporting 5 GHz frequencies, they avoided the international quagmire surrounding that band in various locales. Raspbian on the Pi won’t even turn the 5 GHz radio on until you configure a geographic locale for this very reason…

It’s a little unclear whether you should expect 12-13-14 to work in the US (see https://en.wikipedia.org/wiki/List_of_WLAN_channels and https://www.duckware.com/tech/wifi-in-the-us.html#24g - but of course use your judgement re: how authoritative those are…)

(update - it might be your hub not supporting those channels based on regulatory settings)

Yet another reason I really wish WF supported 5GHz for the hub. The 2.4 GHz spectrum is simply a mess in many locations.

Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Channel 36 : 5.18 GHz
Channel 40 : 5.2 GHz
Channel 44 : 5.22 GHz
Channel 48 : 5.24 GHz
Channel 52 : 5.26 GHz

Hi Gary,

The hub support channels 1-14, but there’s a catch. Channels above 11 aren’t allowed to be used in the United States, so the hub will only use channels above 11 if the access point is configured to a higher channel. The Hub also won’t do active scans above 11 when searching for a network.

I would recommend not configuring your network gear to use anything above channel 11 if you’re in the United States because of frequency restrictions and potential interference issues with licensed systems.

Thank you, Rob. That’s what I needed to know.
