I have IPv6 on Comcast and it does cause some problems with performance and unpredictability. I do not it and don't want it.
For example on an older Mac PowerBook by disabling IPv6 on the network preferences I went from 4 to 5 minutes per web site and search with goggle to almost instant after turning off IPv6 on the Mac. For all my devices I want to completely disable this protocol.
It is clearly not ready for prime time usage.
How do I do this on this router??
Thanks
