LabGuy,
We have Comcast, too here in FL...though not that step up.
Results of a test I run on occasion below. I run the test through
the same site and site's geographic "tester", trying to keep it somewhat
level. I run it out of curiosity and send back to my friend in the Mtns who
provides our wireless connection there, just to bust him and show how high
the bar can get, lol!
