Hi there and Welcome to Ten Forums,

Have you checked any latest driver for your 3G modem? I'd also find out if there's any incompatibility issue.

Microsoft have have been releasing a few updates for Windows 10, hopefully that will resolve all issues that you're experiencing.

Please keep us posted.

Hello,

I'd experiment a different driver for Windows 10, a universal one might work. Find out if there's an optional driver's update for the printer in question.

Hi jeffrys,

I'd check if you have the latest Windows Updates including IE.
