Cant connect to Synology RT2600ac

@shorerider The TM Gateway and Synology wifi router both act as DHCP servers, so they both hand out IP addresses when devices connect to the wifi network. This is problematic and called "double-NAT." If I were you, I would do a few things:

1. make sure the ethernet cable from the gateway is plugged into the blue WAN port on the wifi router
2. put the wifi router into “bridge” mode (usually under network settings
3. restart both and retest

Then, your gateway will be the only one handing out IP addresses. Also, make sure you set up seperate SSIDs on gateway using the TM Internet app.

Let us know how it work.
