I recently upgraded my Bellsouth DSL speeds 6M/512K. When I run the speakeasy.net speed test I am now getting the 6.0Mbps down but the upload speed is clearly pegging at 384Kbps as though there was a restriction at that rate.
I have talked to tech support but they don't see any network problems. They are only obligated to provide between 320K and 512K for the level of service I ordered. I understand that the up speed can vary but it just looks suspicious that the upload speed is exactly 384Kbps which is the level of service I was previously paying for.
How is the upload speed controlled? What questions do I need to ask tech support to ensure that I am not artificially restricted?
