When I had those [link|http://z.iwethey.org/forums/render/content/show?contentid=137017|parts], my Motorola SB5100 fed my DI-704P which served up DHCP addresses. I didn't try using the WAP to serve up the addresses but it should work. (The 704P was a historical artifact of when I was using it with my dial-up service. I just never removed it when I got the cable internet.)

I never did anything to the SB5100 that I recall. I never installed the CD software for it - that I'm sure of. I always had something else serving up DHCP (my Buffalo 802.11g router is doing it now).

Are you sure the modem cable is going into the WAN port on the WAP? Does the WAN light go on on the WAP?

Whenever I had to power things down, I would turn off the SB5100 and the other boxes. Wait 5 s, then turn on the SB5100 and wait until all of the lights reach their steady state. Then I'd turn on the WAP, and wait a while, and then I'd turn on the bridge. It was pretty rare when things had to be cycled.

I hope it's something simple. Sorry it's been a bear thus far. :-(

Cheers,
Scott.
