After being coerced into Comcast bundling, the only thing of interest to us was the
blast speed...should be about 50.
After installation, no blast speed. Did my own research which stated that there needed to
be a modem upgrade for it to work. The installer apparently didn't know. So we got a
return call-back with the new modem.
The speed after installation was 51. Yay....but wait, three days later it was back to 30.
What happened?
