P1 Wifi Connectivity with AC type only router

We manufacture a device that includes the Particle P1. https://store.particle.io/products/p1.

A customer using a https://www.cox.com/residential/support/panoramic-wifi-from-cox.html modem/router is having trouble connecting.

The specifications on their website state that the broadcasting band is 802.11 AC, but the particle P1 specifications state 802.11B/G/N. From what I’ve read online these technologies should be backward compatible.

Has anyone received any troubles connecting a P1 to this router or any others that broadcast AC only?

Hey @rickkas7 ,

Good Morning,

I was wondering if you would happen to have any clue as to why P1 is not able to connect to a router broadcasting AC type band?



802.11ac uses the 5 GHz band. The P1 (also Photon and Argon) can only connect on the 2.4 GHz bands. 802.11b and 802.11g only use 2.4 GHz. 802.11n uses both.

It won’t be possible to connect to an 802.11ac access point, or 802.11n in 5 GHz only mode.


we checked with the user, and had a look ourselves via the screenshot. P1 in pairing mode is able to see the 2.4 ghz connection and not the 5ghz connection, but yet unable to connect to it. Would it have something to with Authentication type of the password(WEP, WPAII)?

Some users have had trouble with certain APs that broadcast using the same SSID for 2.4 GHz and 5 GHz. Sometimes it’s fine, I have a Ubiquity UniFi network of APs that use the same SSID for both and the Photons, P1, and Argons work properly.

WEP, on the other hand, is a completely different matter. It is possible to make a Photon or P1 use WEP, but you don’t actually enter the key, it must be transformed first. It’s described here:
