Practical, methodical checklist for a Cell C 3G USB data card (targeted at ). The aim is to isolate whether the fault is provider/SIM-side, the USB modem hardware/firmware, or the PC’s network stack and drivers. This complements requests for more detail from and the outage/hardware ideas from and by focusing on device- and PC-level diagnostics that clarify the root cause.

Collect the essential diagnostics first (these make troubleshooting fast and precise). Note OS + bitness, exact USB modem model and driver version (Device Manager → Properties → Details), and capture these command outputs (Windows):

ipconfig /all
route print
ipconfig /flushdns
netsh winsock reset

If a PPP/USB adapter appears but no internet is assigned, include the ipconfig /all output — it shows whether an IP, gateway and DNS were assigned.

Driver / connection-manager checklist: uninstall any duplicate connection-manager suites, then install the latest official driver/firmware from the modem vendor (not from a random site). After reinstall, check the connection profile’s APN and authentication fields (many providers require APN-only profiles). If the modem shows “Connected” but there’s no internet, check for missing default route/DNS entries and for third‑party security software interfering with the modem’s connection.

USB / power / hardware checks: try a different USB port (avoid unpowered hubs), disable USB selective-suspend and the “Allow computer to turn off this device to save power” option for USB Root Hubs, and test the SIM in a phone or the modem in another PC to separate SIM/account issues from modem/PC faults. Capture Event Viewer (System) errors related to USB or the modem.

When posting follow-up, include OS + bitness, modem exact model, driver version, outputs of ipconfig /all and route print, and screenshots of Device Manager/connection manager. Do not post IMEI, full SIM number or PIN in public. With those diagnostics it’s straightforward to tell whether the fix is an account reset, driver/firmware re-install, USB/power change, or deeper network configuration.

Try resetting your modem and router. You can do this by holding down the back button of your modem ( Only for linksys ). Try using your computer and access other network, if other network allow you to connect to internet something is wrong with your network or conputer. Make sure your firewall is not on to block internet connections and your wireless is working wel?. Can you access internet using an ethernet cable?
