I have read several threads about optimum online and connection problems. I have followed the advice of changing the port and have done so, to 64049 it went to three bars for about 10 minutes and back to one.

I have
Windows XP
Pentium 4
Optimum online (Brooklyn)
The test for 6346 worked

I am not sure what to do I have tried several methods without any luck. What can I do?? Please help
