The MIFI 2200 shows connected, but not connecting to internet. I can ping the gateway and dns, but no internet access.
Oddly, the MIFI is not working on the laptops that had the UM175 previously installed. Other laptops that did not have the UM175 work perfectly with the MIFI.
I also tested on a desktop (no previous installation of UM175):
Set a system restore point. Installed UM175 drivers/software. Installed MIFI 2200. Connected, but no internet.
Restored computer. Installed MIFI 2200. Worked.
So it seems to be something with the old UM175 software. I tried uninstalling the old software, drivers, even registry entries. Still no access with the MIFI 2200.
Anything else I could try, barring a total wipe of the OS and reinstallation?
