Thank you so much for this!!
I remembered I have a backup modem from Huawei, so I uninstalled the old Mobile Partner and moved it all to the new Huawei modem. I couldn't install it though. It opens up in a HiLink thing in internet explorer, it's basically the same thing where you can connect your internet and check your messages, just over a browser I guess? So I have had the internet on for a couple of hours now, and I haven't experienced the problems I had before. So far so good. In the bottom right of the screen where we can view our WiFi it says "network: connected" and there's a picture of a computer screen with a cable on the side. I guess it works? It's different from what it did before with the old modem, but so far so good. I will let you know if anything happens, and thank you again SO much for doing this.
I wrote on another site about problems I experienced with a wierd mechanical stuttering sound coming from the laptop. It came whenever I went into an internet browser, though was a lot worse when going on Google Chrome. People told me it was because Google Chrome is a CPU drainer. However, after putting in the new modem and using that his way instead, the sound is no longer there. I'm thinking the old one was the cause of it considering the errors in dxdiag as well. Now I just hope all the good-ness lasts, lol. Thank you again.
