As we speak I am on hold with Cox trying to figure out my issue. The rep won't transfer me to a Level 2 agent, and he is clueless. I need some help!

If anyone can offer me any help, I'd really appreciate it! I've been fighting this thing for over two months now, and what was first just a tid bit annoying, is now really bugging me. If anyone could just help me figure out what a few things are, that could help a bunch too. I'm somewhat knowledgeable with networks and such, so some definitions and common usages/locations would benefit my troubleshooting a great deal What is a network switch and where is it located? Should I get a different Ethernet Adapter? I'm being rushed so I cannot properly finish this post, but I'll try and further it later. Thanks in advance
