With the MR60 + 2*MS60 configured as a router, my wired devices (e.g. a Synology NAS) could not be seen from my wifi devices (e.g. a Macbook Air), and vice-versa, but wifi devices could see one another.
Solution/workaround: I put my old TP-Link router back in place as a router, with wifi disabled, and then configured my MR60 as an access point. Now my wired and wifi devices can all see one another. I am back in business accessing my NAS from my Mac notebooks. I now lack the security and logging features that I had with the MR60 in router mode, but at least my home network is now in a working state. My wired devices (NAS + printer + voip telephone box) are attached to the MR60 ethernet port via a Netgear switch. My old TP-link router now has just one ethernet cable to FIOS internet and one ethernet cable to the MR60 WAN port.
I would love to have some sort of firmware update that would allow traffic to/from the wired ports on the MR60/MS60 to be bridged/switched onto the wifi network, so that my wifii devices could talk with my wired NAS when the MR60 is in router mode. Then I could finally discard my old TP-link router, which is slowing down my uploads, and whose security is probably less up-to-date than the new MR60's security.
Many thanks to Louie from customer support ticket # 43957276 who spent a lot of time trying several possible ideas to help me out via chat yesterday. While we were not able to resolve the issue with the MR60 in router mode, I do appreciate the support. I hope we can find out from the firmware experts whether this is a feature or a bug. It sure seems like a bug to me: if you have a shared printer or shared NAS plugged into a wired port, you certainly want to be able to reach it from your wifi network.
