This listing is for a 3 pack of TM-AC1900 routers which are the same as ASUS RT-AC68U. They are running the latest firmware 12.4. All three routers are working perfectly. They come with 3 original power supplies. I had these routers set up in a mesh network configuration that completely covered my 3 story house in great wifi. These are superior to other cheap mesh networks because there are plenty of LAN ports on each unit. This is critical for running low lag gaming systems. The reason I flashed them to ASUS Merlin software was to get the full potential out of these great routers. These routers, when configured, eliminated my homekit ‘No response’ issues. There are no stock router firmware out there with this granular setup. I was able to run 60+ IoT devises and 3 streaming cameras no problem. Speed tests on a 1gig system would average 700mbps. These router have an ASUS app that lets you remotely manage wifi. Very convenient. Moving to new smaller space and I don’t need a mesh anymore. My loss is your gain. This is a set it and forget it setup.
