Connecting Linksys B and G routers to a prosafe, woohoo!

[Dillusion]

I just got a WRT54G to add to my little network setup. Initially I just had the prosafe (FVS114) and the B-router, but I want faster wireless so I got the G. Now when I have both wireless routers (B and G) connected to the FVS114, but the G router wont let me fully connect. When windows tries to connect it says limited or no connectivity...but the B router still works fine.

Any ideas?
