Alright - I think I’ve figured it out - and it is a MAJOR issue with the Wyze Car.
First - when Wyze says it will connect to 2.4Ghz networks only - IT WILL ONLY CONNECT TO A 2.4GHZ SPECIFIC SSID NAMED NETWORK. Many routers - mine included - combine the 2.4Ghz and 5Ghz name into the same name, and let the device toggle between the two. AND I CAN’T RENAME MY SSID TO SEPARATE THE TWO NETWORK SSID NAMES. I have an Netgear Orbi Mesh Network with one router and two satellites.
There WAS a hack to separate the SSID names on the Orbi - but that has since been removed, and from what some have said, even if they are renamed, Netgear will “combine” the two SSID names into one and the same again - so you’ve lost your separately named SSIDs.
And before anyone says anything - I have about 15 Wyze devices - that are ALSO 2.4GHZ specific - connected to this same combined 2.4/5Ghz SSID name, and have NEVER had an issue setting them up, or using them. Devices of every kind. V1 Cams, V2 Cams Pan Cam V1, Bulbs, plugs, outdoor cams, sensor kits, etc. NOT AN ISSUE. I have also had many other 2.4Ghz devices connect to this same Orbi router with NO issues.
However, the firmware on the Wyze Car will just flounder and die trying to connect to the router with the combined name (again - as far as I’ve seen has NEVER occurred with any other Wyze device) and will fail the “firmware update”. So the car is useless.
I’ve been experimenting, and have some crappy - OLD - WAP that is 2.4Ghz only, The WAP can’t be updated anymore - so it’s insecure, and I get channel issues with neighbors and myself, as I’m not consuming more than one 2.4Ghz Channel with this type of setup. I simply can’t keep this device up.
I also don’t know how a phone hotspot works, unless the phone is specifically 2.4Ghz only. Depending on your device, you may be able to ONLY support 2.4Ghz, or might be able to support both 2.4 and 5Ghz, and some might allow you to support only 2.4Ghz or combined 2.4/5Ghz (depends on your phone, model, and OS version). So trying to set this up for use away from my home might not be possible.
Overall - it appears that Wyze has a major issue with the firmware for the Wyze Car - since it can’t connect to combined 2.4Ghz/5Ghz WAPS where both are using the same SSID. I’m sure there are other older devices that can’t do this either - but I haven’t run into one in years.
