Re: Upgraded To Extreme 105 : YouTube and Browsing Issues

Any chance only having 1 16QAM upstream is causing any restriction?

Just throwin' it out there...

Per the QAM FAQ »Comcast High Speed Internet FAQ »What is QAM? , a 16-QAM running at 2.56 Msym/sec has a total Payload Rate of 9 Mbps, so you would not get anywhere near the nominal 20 Mbps upstream rate using that!
