Norton, Windows 10 and Internet connection problems

Ever since installing Norton on my new HP Stream and updating to Windows 10, I have continuous internet connection problems requiring me to unplug and re-plug my wireless broadband device.  Wondering if it has anything to do with Norton/firewall?  I don't know enough to have the first clue as to how the whole Norton thing should be configured.  I am using a Huawei broadband dongle to access the internet.  Have tried both google and Edge; Edge is no good as I can't use my email program properly.  I don't seem to have internet explorer at all as it goes instantly to Edge.  Don't know if this is a Norton issue, a Windows 10 issue or an HP issue! Help?
