Exactly but can't do much thing...

Well, I seldom go back to my hometown, so getting another TP Link there is a waste. I also go to my sister's house quite often...
next time u go back PD, bring the MR3420 home, plug in the E372 into MR3420,
Disable WiFi on Mr3420 use LAN only, then connect the LAN cable into Aztech
WAN PORT on one side and the other side into HW550 Ethernet Port, meaning u are supplying a WAN connection from MR3420 into HW550
From there u can use WiFi and LAN on your HW550, your connection will be super consistent.
I tried with my MR3420 V1 > MR3420 V2 this morning.........no need OpenWRT too
I am thinking of getting either an Asus or MikroTik for the router #2 to getter better WiFi and Gigabit LAN connection
