It depends on the type of bridging you need. You’ve presented a mix of wired and wireless devices, so it’s not clear what your intentions are.
You can always create a WIRED bridge using an Ethernet cable between the WBR-1310 and the WAP54G to create a local wireless hotspot. That’s pretty easy.
Wired Bridge to a Wireless Access Point (aka AP mode)
[wbr-1310]
<-- wire -->[wap54g]<-- wireless -->[various wireless devices]
The problem comes if you want to create a WIRELESS bridge.
Wireless Bridge to a Wired Access Point (aka AP Client mode)
[wbr-1310]
<-- wireless -->[wap54g]<-- wire -->[various wired devices]
Wireless Bridge to a Wireless Access Point (aka Wireless Repeater mode)
[wbr-1310]
<-- wireless -->[wap54g]<-- wireless -->[various wireless devices]
The WAP54G (in AP Client or Wireless Repeater mode) uses a technology called
WDS to support wireless bridging. But WDS is not a WiFi certified protocol, so implementations vary widely, and thus compatibility is a common problem. For all intents and purposes, your WAP54G will only wirelessly bridge to another WAP54G (and possibly a Linksys WRT54G router, but not even sure about that). IOW, even getting it to work w/ the SAME manufacturer is a challenge. But now you’re trying to wirelessly bridge to a DIFFERENT manufacturer (D-Link). While you can always try, your chances of success are probably 1/100.
What you really want/need is a “universal” wireless Ethernet bridge which will wireless bridge to ANY wireless router/AP.
