RT2600ac
I have an RT2600ac and am considering adding an MR2200AC, to get wireless coverage at the far end of the house.

The manual on the MR2200AC is not super comprehensive, unfortunately. Need to know whether the MR2200AC can be connected by (obviously very long) ethernet cable to the RT2600AC and, if so, whether the cable would be connected to the WAN or LAN port on the MR2200AC. If it's connected to the WAN port, can the LAN port be used as an ethernet passthrough?

So for example:

RT2600ac lives at one end of the house; there is an ethernet cable that runs to the other (far) end of the house. That ethernet cable currently connects to (say) a device that has ethernet but no wireless capability.

Can I connect MR2200AC's WAN port to the far end of that ethernet cable, and then connect the wireless-less device to the LAN port on the MR2200AC? (And have wireless coverage from the MR2200AC at the far end of the house?)

Tks!

My setup:

RT2600ac as Internet gateway and primary mesh access point (i.e. any MR2200ac that I add as mesh access points will take all their configuration from it). This is wired to my ISP's router, which is in bridge mode, and provides wired LAN and wireless LAN for the home network.

MR2200ac as mesh access point controlled by the RT2600ac using an ethernet backhaul/uplink connection to the RT2600ac's LAN port (actually I've two unmanaged TP-Link switches in between and the MR and RT connect to these and then switches to each other).

The initial configuration has to be done wirelessly, meaning: place the MR2200ac close to the RT2600ac but do not connect with ethernet and then add the MR to the RT's network using the RT's SRM portal (think it is the Wi-Fi Connect application, so long ago). Once the configuration has completed you will be able to select the backhaul/uplink connection, but this is defaulted to 'automatic' so really you don't need to do anything.

Now you can unplug the MR and place it where you want and connect ethernet back to the RT. It will auto-sense the best connection and use that (unless you change that setting).


You're lucky, I could just test this without getting moaned at...

Connecting a local device to the ethernet ports of the MR works like this:
  • WiFi uplink: No. I get no DHCP assignment to a Mac Mini's ethernet interface regardless of plugging into MR's LAN or WAN port.
  • Ethernet uplink using WAN port: Yes. The Mac Mini get's an ethernet DHCP assignment when connecting to the LAN port.
  • Ethernet uplink using LAN port: Yes. The Mac Mini get's an ethernet DHCP assignment when connecting to the WAN port.

This surprised me as I thought that the local ethernet connection would get backhauled over a WiFi uplink. But I repeated the quick test and it was the same. I used to use two Airport Extremes to create a wireless link to wire-only devices. Sometimes I've used small TP-Link client/router devices make wired devices wireless (TL-WR802N | 300Mbps Wireless N Travel WiFi Router)

@fredbert - thanks for the thorough testing, clear reportage and the good news! I’m looking forward to this!
