DIR-615 WDS or Bridge Mode
I have two DIR-615's hardware version B2, firmware version 2.25. They do not currently support wireless WDS or bridge mode to each other (but a Linksys WRT-54G with DD-WRT firmware can use wireless WDS to connect to them in wireless G mode).
If anyone actually knows how and/or has alternative firmware for the DIR-615 that really support wireless WDS or bridge mode using G or N, I'd love to know about it. I've looked at all of the alternative firmwares, but haven't found one yet that will work (DD-WRT, OpenWRT, Hyper, etc...)
D-Link if your listening, there are lots of DIR-615 owners who would love this capability. Linksys' WRT-54G does it with alternative firmware!!!
