Device Compatibility as of Firmware 4.0.Gr5
The only modems that 3Gstore can confirm as compatible with the WiFiRanger are the Sprint/Verizon/Datajack USB760 and the Sprint/Verizon MiFi 2200. Any other USB modems MAY work but we cannot guarantee compatibility.
The WiFiRanger also works well with hotspot devices (like the Sprint MiFi 4082 or Verizon MiFi 4510L as well as phones that feature a mobile hotspot option).
