said by flashcore:While I don't have the 300Mbit plan I do have the 150, and there is no way Concast is going to match the 70Mbit upload speed with there existing setup, they also wont be able to get the low pings that FiOS can achieve due to the overhead in docsis networks. Lastly, what good is 300Mbit on Concast when they purposely oversubscribe there backbone links to over half the internet causing 500ms+ pings during peak hours.
* Speedtest's flash program cant handle the upload speeds, its a known bug that they have fixed but the people running the test sites haven't bothered to upgrade yet.
My Comcast pings are just fine! I do see a limitation for upload. The meter bangs up against the 12Mbps limit pretty hard when I do testing.
ShaperProbe is also consistently matching with Speedtest. Don't believe everything you read. Some markets are getting excellent service from Comcast.
