Using a Google mesh router, it does not create separate SSID between 2.4 ghz and 5 ghz bands and my phone automatically connects to the 5 ghz band which creates problems trying to connect any further wifi devices that only use the 2.4 ghz band to my google home. Is there any work around on either my phone or with the router settings? I have now encountered this issue with 3 separate different devices.
IoT manufacturers' devices should handle combined SSIDs, but many don't.
Things to make sure, before trying various workarounds:
• Make sure that the IoT device(s) in question supports the amount and type of characters used in your chosen network name (SSID) and password; some might have limitations here. In general avoid anything but a-z in the network name. I've heard of devices not supporting whitespace in network name (SSID) or password for instance.
• Some IoT devices have alternative set up procedures if the regular way does not work, which could help.
Workarounds that might work:
• Use an old iOS, iPadOS or Android device that only supports 2.4ghz to set up the IoT device.
• Buy a cheap access point or repurpose a wireless router or range extender to broadcast a 2.4ghz only SSID with a different name than your Nest Wifi network name. Connect it by ethernet cable to the primary/ main/ master Nest Wifi puck preferably. Add more ethernet ports by using an unmanaged switch if need be ( https://support.google.com/googlenest/answer/6274262?hl=en ). Make sure this additional Wi-Fi broadcastong device works as an access point only, else you might not be able to connect to the device in question from a device connected yo your Nest Wifi network.
• Walk far enough from the Nest Wifi puck(s) to make sure your phone/ whatever device used for setting up the device in question connects to the 2.4ghz network, then start setting up the device.
• Turn off your Nest Wifi network by removing the power. Feed your laptop (Windows or Mac) an internet connection, either by ethernet cable from your modem, or by mobile network tethering + USB. Then use your laptop to host a 2.4ghz only Wi-Fi with the same network name (SSID) and password as your Nest Wifi network. Get your IoT devices connected to it. Remove the Wi-Fi hosted by your laptop, plug in Nest Wifi, and the IoT devices should jump to the Wi-Fi provided by Nest Wifi.
Thanks for all that info, olavrb!
I just wanted to jump in real fast to see if you saw olavrb's reply and to see if you still needed some help on this or if you were able to get it sorted out. If you are still needing some help, just let us know and we'll be happy to continue helping.
