Troubleshooting

I have Spectranet connection in Bangalore. I like its speed and service. They provide a default low-end Beetel WAN Router with single antenna. I have D-Link ADSL moden with dual antenna, but unfortunately I couldn't bridge or bind this D-Link modem-router to my Beetel Sepectranet connection. I called Spectranet engineers and they came and configured it. Now, I can use wifi both from my D-Link and Beetel as well as LAN through cable from both routers.
Unfortunately, I had to reset my D-Link modem and I lost all the config. I called spectranet and they do not support bridging or ADSL config any more.
I want to configure my D-Link again to my Beetel. Anyone can help/guide here would be much appreciated. You can also PM at benzmar at gmail dot com.

I can understand that you want to use your D-Link modem+router to work as a second wifi router along with your beetle one. You have to search for an option "use as router only" in your D-Link router page and nothing else. Earlier you must be having a LAN from your beetel to your dlink (on one of the ports, probably on port 1 or 4).
