Lost connection on upload, does relate to flight sim

I just had cox internet installed sunday.

so far I can not do any big uploads without losing my net connection and having to reset the modem.

I mean big upload like a mega pack, or a 2 gig video to Youtube that I frapped and do not want to convert smaller because I will lose my quality

I got a new modem today. still not fixed

tech changed wall panel. still not fixed

tech on phone said account had not been properly activated...... guess what?

still not fixed -- yes I am writing poetry here

I am on win7 pro, disabled wifi, disabled blue tooth

see some kind of tunneling in my ipconfig and was told by a forum I can remove that.

I was told to get IPv6 out of my network stack also because it is not used. I probably will not do that.

It is a cisco router / gateway da da da da ethernt / wifi (you get my drift)

Cisco is docsis 3.0

I was told to do something at command prompt with winsock but that did not help.

Also I am running windows7 on a pc that was designed for windows 8.1 it is a Dell XPS

Moral of the story...................... still not fixed
