Any DIR series router is just that, A ROUTER with HOST WiFi AP capabilities. And just AP capabilities, no Bridging or Relay capabilities are supported. There are 3 WiFi modes of operation, AP, Bridged and Relay. All different.
If your trying to get internet from the host building WiFi access, then one of the DAP model devices will be able to handle this.
For a suggestion, I might give the following a try:
Building WiFI AP> Wirelessly Bridged to a Dlink DAP-####<DAP-####>PS wired to the DAP. This is only one suggested configuration. There could be others and better configurations as well.
Is the buildings WiFi access your main ISP internet access point or do you have a wired ISP modem connected to the 655?
DIR series routers are designed to work with ISP wired modems to get access, then provide WiFi access to that connection thru the router and the wired connected.
Setting up DAP is easy as well, and have set up wizards to help you get it configured.
