I just got rid of an old Netgear M100 and replaced with this. I paid $99 a few weeks a go. This is a great deal. It's a full ASUS router in a portable form factor. Equivalent of an RT-AX3000 less a few ethernet ports. So it can function as a mesh node, mobile tether and all the rest. The only unique software feature seems to be the public WISP mode. Don't believe it can run Merlin though.
Great little flexible device for on the road or for some testing use.
The ASUS has 1x WAN and 1x LAN (Gigabit)
