Wi-Fi no longer recognised
Sorry I can not access it to see what version I was running, apologies in advance, it has been running fine on Raspberry PI Zero using my Wi-Fi network, I did do a ssh sudo apt update and then sudo apt full-upgrade only because nodes was old version and wouldn't update via the HomeBridge web interface.  Now I appear to no longer have my existing WiFi network access.
I can get to the HomeBridge WiFi SetUp from my iPhone, but interestingly the only network showing in the dropdown list isn't mine?  Our neighbor has just gotten home from being away so I'm guessing it's seeing there's. 
I originally thought it might have been a hardware issue so to isolate that I ran up another MicroSD card with rasbion and it works just fine.
I have also download and then tried the latest HomeBridge Raspbian-Homebridge-v1.0.23.zip image file, but, I'm getting exactly the same issues as the working one.  Not seeing my Network only the other one?
Suggestions anyone?
