WiFi Notecard on Access Points that combine 2.4 & 5 GHz

I have a device located in an area where it regularly drops its cellular connection, however there is a WiFi access point nearby. So I started testing a WIFI Notecard as a potential replacement and just learned about this caveat contained in one of the guides: “Please note that Wi-Fi Notecard is only compatible with 2.4 GHz Wi-Fi access points. Access points that combine 5 GHz and 2.4 GHz with the same SSID may cause issues using the Notecard.”

I’m wondering if any workarounds have been identified that can mitigate the issue, or if it’s just an inherent part of the hardware and can’t be worked around without changing hardware.

Thanks in advance for any suggestions.

Hey @noforan,

The Wi-Fi module built into the Notecard can only talk to 2.4 GHz networks at the hardware level.

Because of that the only “workaround” if you’re having issues would be changing the network itself. Not sure if you control the network at all, but some routers that combine frequencies give you the ability to split them out in their settings.

Hi @tjvantoll

I have done what you’re suggesting on my home network, which is how I was able to test it, but this is on a college campus and I have no control over their network. We are literally doing a science project there so, assuming their AP has that capability, I might be able to prevail upon them to carve out a separate 2.4 GHz network for this purpose, if in fact it’s a problem. I won’t know until I test it there, but wanted to know if I had any other options.

thank you!


Ah, got it that makes sense. Best of luck!
