Other options besides cable and fiber?

What other options are available that Is consistent,  and isn't "land based"?

I have 1 service provider in my area (Cox) and there has been issues in my area for years now and they can't seem to resolve it and I'm fed up.

It's gigabit internet and I often get ping up to 1,000ms.

Is there any options that would suffice for gaming online?

I know there is LTE services but all the companies say they don't support my area, which is odd..

What options should I look into and how do I go about acquiring it?

Thanks in advance!
