I have a rather strange symptom with my RT-AC68U which is that my work laptop's Cisco Anywhere software connects just fine through WIFI but when connected via network cable it says it has no internet connection. Other computers have no problem with a wired connection; I am using my personal laptop connected via wire to type this now. Any guesses as to what about Cisco Anywhere and the wired connection might be the problem? It is almost certainly just a case of something in the router's software that is filtering the Cisco.
