index2 update and inability to connect to wifi

Help.

My scales were ok and connected to my wireless network. 

Then they would not. 

Days later I have tried all options and studiously re-read the instructions time after time.

Last effort today before I through the machine out is to try and get it to update firmware on another wifi network. Why?!!

So very unhappy with machine and its software. 

How long does the firmware take to update ....? I read possibly leave it updating for several days. Is that evenly remotely true?

Thanks for reading.
