I bought a new Asus RT-AC1200G+ to replace my RT-AC51U for better signal and Gigabit Ethernet. It’s much faster to copy files to/from QNAP TS-119PII now. But I notice it drops internet connection several times a day, I am sure there is nothing wrong with my tethering device as described in “Android USB Tethering Drops and Data Usage Crashes, try Reset“.
