Attached is the wifi tether app which does work, download and install it on your phone.
Once installed and running; the a500 will see the network and connect to it, but still no internet when the browser is opened.
To fix that: open it and go to menu > settings > Change LAN > and select 192.168.3.0/24.
Hooray, it works; Just in time for a road trip
I hope this is helpful for others.
