I have a Sprint Mifi 8000 that I am trying to connect via USB for Tethering. I followed the steps to install a USB mobile tether and it works perfectly with my phone. However when I connect the Hotspot device it shows network device is not present. When I plug in the Mifi it will prompt the option to connect via USB Tether however the router is not listed in the connected devices after this is selected. I am using a Linksys 8300 router.
