I'm no fan of Windows 8 either, but in case you didn't know, Windows 8.1 is supposed to be out in the next few weeks. I don't know if it will help your problem or not, but before you ditch what you have, you might want to wait and give it a try. I don't use 3G or 4G so I couldn't say whether it will help, but MS touts it as a big deal. I've been using the 8.1 preview since it came out in June, and I'm not impressed with it, but still it's something to be aware of. Another thing to be aware of is Classic Shell which you can download from http://www.classicshell.net . It makes Windows 8 look and feel pretty much like Windows 7.

Good luck.
There aren't many unlimited data plans in the US. For those of us who travel across the country, we need mobile data service. With careful management, 5GB can sustain a user for a month. Unfortunately WIN8 chews large holes in mobile data plans. Simply using the WIN8 browser to scan news will trigger endless (and apparently unstoppable) video streams. The overhead adds up in a hurry. I have used a Verizon mobile hot spot for the past 2 1/2 years and rarely exceeded my monthly 5GB limit using WIN XP and various iterations of Android. 2weeks after firing up a new HP laptop running WIN8 and I was 2GB over my limit. 10 days into my second month and I am at the 90% usage mark.
Learning curve aside, I am about to admit defeat and dump my new HP laptop for something more user friendly. Microsoft, I was using a PC before Bill Gates got into bed with IBM. Had just about everything in the way of operating systems starting with BASIC &.........
I like Microsoft, but this version of Windows needs some drastic fine tuning!
