One of our users is trying to use a Verizon wireless / USB interface on a couple of Windows 8.1 laptops. We're getting strange results:
- when connected to the Verizon interface, most often, web pages won't load. The connection is there but the pages won't load. They do load using other connections.
- It appears that the Windows firewall is involved as if it's turned on or even if it's turned off, as long as it's the only firewall installed then the problem occurs.
- If we install the Kaspersky firewall then the problem goes away.
- If we install the Comodo firewall then the problem goes away.
So, it would seem that whatever gets shut off when a 3rd party firewall is installed does something to allow the connections to fully work. After all, they do "disable" the Windows firewall somehow, yes? And this appears to be different than turning off the Windows firewall by itself.
I'm not satisfied with having to install another firewall and would like to get the Windows firewall working.
But I have NO idea what to consider.
