So I have switched. Using the new CGN3 alone, my wired speeds are better then advertised (77mbps) and my wifi was 22mbps down.
Using my existing router (Netgear N600) cut my speed by more then half (32-35mbps) wifi dipped a bit (16mbps)
Any thoughts as to why the netgear would cut the speed so much? All I did was bridge the CGN3 and no settings were changed on the router. Prior to this I used the cisco and had same speeds regardless of which device I used (hardwired)
