no its a speed upgrade to match verizon fios service
perferd intert axx will be
old speeds 4/512
new speeds 5/2
premire axx is this
old speeds 5/768
new speeds 15/2
at least here in VA the new speeds very from 9/1 to 15/2 depends on where u are
well me and my friend have each of the modems we get the same speeds
but in the best case SB5120
it has alot better support for it and is widely used
and is good with the new speeds
