How to resolve the WNET Run Fail Error on the 7210 Devices
Prognosis
Merchants using NewPOS 7210 devices are experiencing an inability to trade due to the “Wnet Run Fail” error. This error is caused by the expiry of the WNET file, which manages SIM-based wireless connectivity on the device.
Impact
Devices relying on SIM connectivity are unable to establish a network connection, preventing merchants from processing transactions and trading.
Action Required
To restore connectivity and resume trading, the following actions are a necessity:
Pre-Step - Ensure device serial numbers impacted are loaded onto the terminal management software (TMS). This step is to ensure the newPOS application update is made available for download to the devices. This should be actioned by iVeri/TouchPoint, acquirers can provide a list of serial numbers affected.
Connectivity and application update - The merchant device must have connectivity via WIFI or by changing the Date/Time on the device. Once connected, the NewPOS application must be updated via the TMS(Terminal Management System), there are two resolution options available:"
