How do I start research solo?

I'm a recent CS grad from a low tier college where research wasn't done. I have this passion for research, analyze, and write infomative papers.

Since I already graduated, how do I get into research solo since I'm not under any supervision at the moment? Should I look for an Msc in research programs at mid tier unis since good ones won't accept without research experience? Is there any community online that allows me to collaborate and learn with them to publish in reputable journals?

Thanks
