When I had 15 Mps service, I was pleased to see that the speed was routinely in that ballpark. Upgraded to 25, and got a nice upward bump (near 20). Now that I have "upgraded" to 50up/25down, I am getting less than 15 Mps. I use both SpeedTest.net and the VZ test. I'm not running any thing exotic, am not a heavy user, don't run a bunch of simultaneous data-rich connections. I have tested at many different times during the day and night, used different test servers, etc. I was a very early adopter to FiOS here in Silver Spring MD. It could be a case of maybe an issue with the ONI, which was installed in Jan 05.
Was considering upgrading to Quantum, but apparently, the 50 Mps IS Quantum.
Does anyone else suffer from these low connection numbers??
