Configuring Tablet to connect to Internet via USB/Ethernet adapter



The CNCentral POS and Daily Wrap Up apps are designed to function in areas with poor WiFi. This requires being able to periodically connect to internet, ideally at least at the beginning or end of the day to receive the latest sync of accounts or menu items.  There may be some situations where constant internet access is still desired in a no-WiFi zone but an ethernet/LAN port is available. 


This document assumes that the Samsung Galaxy Tab A (SM-T350) is used.  A Micro USB/Ethernet adaptor may be used that connects to the Micro USB port on the tablet to a nearby LAN port. 

Recommended Specs:

  • Micro USB connector (to plug into tablet)
  • RJ45 LAN Port (to plug ethernet/LAN cable into)
  • Multiple USB ports (to plug barcode handscanner into)
  • Independently Powered (may provide better reliability and batter life for tablet)

Example from Amazon:

Name: Ethernet Adapter with OTG Cable Hub Compatible for Samsung Galaxy Tab E, Google Chromecast Home Mini, Chromecast Ultra and Raspberry Pi Zero - Micro USB Multiport to RJ45 LAN Network
