I'm not sure as to what the problem is or why so many are posting about freezing issues. I have tried various channels, ( some are down), but freezing doesn't appear to be an issue ?
Perhaps increasing the buffer values, setting up quality of service for your box on your router ? uninstall present software and go back to older emulator or software ? Try changing something and check for any improvements.
Don't waste your time. It the service......
There are a lot of things that can be the cause, if it were the service, why am I not having the same freezing issues ? I get my service from rocket server with no freezing ?
