Have you tried working with your internet provider to identify problems with packet delivery? That is pretty much what is the culprit. It likely has nothing to do with your bandwidth. So long as you have about 1.5mbps in both directions, you have enough bandwidth for gameplay. In the U.S., even the government subsidized programs provide nearly double the bandwidth needed, even more with some ISP's. What matters is the stability... consistently low latency is the key factor. A high error rate or delays in delivering data is what gets you booted. Provided your local network is not at fault (wired and not wifi, no firewall or router rules interfering with packet flow... basically, following their network guide), your ISP would be your best ally in not only detecting delayed/dropped packets but also possibly FIXING it. It is like people forget they are actually paying a company for their internet service... a company with a TEAM of people who actually investigate this kind of stuff as part of their job!
