I have isolated my problem and resolved the issue. I imagine that many WRV owners could experience the same issue I had. The problem appears to be related to an iOS update from Apple in the February time frame. It may only affect certain iPhones. My model is an SE (2020). I used an old iPhone 4S to get the WRV onto my network. Hopefully, Wyze will be able to remedy this with an app update. Otherwise, getting a firmware update into the WRV without it on the network is very difficult for the average user.
The workaround is to try using another device to get the robot vac onto your network. Then, if you are using an iPhone like mine, it will work thereafter. If that’s not your issue, then I can possibly help you understand what support is telling you.
Go into your router or on your phone, etc. and try to determine if you are on a 2.4 GHz or 5 GHz wireless channel. Google for help. You will find those terms somewhere in the wireless setup. The unit only works with 2.4 GHz. If you have other Wyze products like cameras and they work, you have a 2.4 GHz network.
Unlikely, but your named network or password can’t have more than 64 characters.
I would ignore #5. If you don’t understand it, then you don’t have your system set up to work with specific MAC addresses. (Each device has a unique address and you can make your network super secure by only letting in those specific devices.)
