RBR750 in AP Mode Satellites won't connect wireless (only wired)

Hi All,

I've been pulling my hair out for the last couple of hours. Here's the thing:

I've switched internet providers.

Previously I had the RBR750 working as a router in my network. Everything worked smoothly.

In the new situation, the new modem/router can't be set to "bridge mode" (not a feature, alas). 

So, no problem I thought, as the RBR can be set to Access Point mode (AP)

Did that, and lost connection with all 3 satellites. Tried to sync, but that didn't work.

reset all. tried again. nothing. RBR750 works, gets new IP from the modem/router. wifi works.

Finally tried the wired backhaul option, that seems to work. But that really restricts where I can put them. I didn't buy them to be wired up (besides power)

Anybody seen similar behaviour? is there a fix?

Thanks!
