Merchant SkyTab POS Network Troubleshooting Guide

  • Updated

Description: Follow these steps to troubleshoot networking issues for SkyTab POS Ecosystem devices.

Important: This article is for reference only to check what can be done to get the device working before calling SkyTab Support. When the support agent is troubleshooting the device, some of the troubleshooting steps might be repeated for record purposes.

POS Terminal

Red Bar on All POS Terminals

  1. Reboot TP-Link and ISP modem. Check for IP addresses on the POS Terminals.
    • If no IP is shown on the POS (Not Connected), troubleshoot the TP-Link router.
    • If the IP Address shows up on all POS Terminals after rebooting, the ISP modem is not giving a connection.
  2. Check for the red bar after rebooting the TP-Link and ISP modem.
  3. Ensure the ISP modem provides an Ethernet connection. Connect it directly to the POS or laptop if possible.
    • ISP connected:
      1. Confirm that the ISP modem's Ethernet cable is connected to the TP-Link router's WAN port and reseat it.
      2. If there's a switch between the TP-Link and POS Terminal, try connecting the cable from TP-Link to the POS Hub, bypassing the switch.
      3. Reseat cables on the switch and reboot it. If the POS Terminal remains offline, contact SkyTab Support for further assistance.
    • ISP not connected:
      1. Try connecting a new Ethernet cable from the ISP modem to the TP-Link WAN port.
      2. If the ISP remains disconnected after using a new cable, contact the ISP provider and report a damaged modem for replacement.

One or More POS Terminals Have a Red Bar

  1. Check for the IP address on the POS Terminal.
    • If no IP is shown on the POS (Not Connected),  troubleshoot the TP-Link router.
    • If the IP Address shows up on all POS Terminals after rebooting, the ISP modem is not giving a connection.
  2. Reseat Ethernet cables from both sides: Switch (or TP-Link directly if there’s no switch) and Hub. Check for loose cables.
    • If it is an Onyx POS Terminal, connect the Ethernet cable to the other Ethernet port.
  3. If the POS Terminal is still offline after reseating the cable, try a new Ethernet cable.
  4. If the POS Terminal displays a Red Bar after reseating the cable, try a brand new cable, and make sure the network is online. The Hub Ethernet port might be faulty. Try power purging the POS Terminal.
    • Power off the POS Terminal, unplug the power cable from the power outlet or hub, and hold the power button for ~30 seconds to perform a power purge.
  5. If the POS Terminal is still offline after the power purge, contact SkyTab Support for further assistance.

Yellow Bar on All POS Terminals

  1. Restart the ISP modem, TP-Link router, and POS Terminals.
  2. If a Yellow Bar is shown on all POS Terminals after rebooting the network, advise the merchant to contact their ISP to unblock the necessary ports.
  • 123 & IP time.google.com / NTP / This is needed for terminals to call out to an NTP server to keep accurate Time and Date

POS Terminal Is Connected to Wi-Fi

  1. Navigate to Android Settings > Networking & Internet. Ensure the Wi-Fi toggle is disabled and Ethernet is enabled.
  2. If the POS Terminal goes offline after turning off Wi-Fi, check the POS Terminal cabling.
