When your POS station connects to some other WiFi network available within your establishment, your iPad is not able to communicate with other devices such as printers, card swipes, barcode scanners etc.
To fix this you need to go to iPad settings and then tap on Wi-Fi. If your iPad is connected to any WiFi network not named ‘rev+establishment’ or ‘revx’, tap on the name of the network your iPad is currently connected to and then tap on 'Forget this network'. Your iPad should automatically switch back to ‘rev+establishment’ or ‘revx’ network. If it connects to another non Revel WiFi network, repeat the previous steps until it does. If the station fails to automatically switch back to Revel network even after your remove all other networks, you will need to tap on ‘Other’, type the name of Revel network, choose security method WPA2 and then type in the Revel network password into the field. If you don't know the password, please contact Revel Support.
If the POS connects successfully you will need to set the static IP address: tap on name of the network and then tap on ‘Static’. Contact Revel support in order to get the data that needs to be entered in Static IP configuration screen.
When you fill in the Static IP configuration data, in order to make sure that your station is able to communicate with your back-end, check if you can browse the internet with Safari browser. If your able to pull up any website, you can go back to your home screen and start your Revel application. Refresh it, log in with your PIN and test if the station is communicating with other devices on the network.
