Q: Conflicting DGCP Range

Hi

 

I really need some help here! I thought it a good idea to buy the new Airport Express to get wireless coverage across the house (ground, 1st and 2nd floors).  I have a wall connection to the Airport Extreme acting as my main router, then in the downstaris lounge the Express works just fine, green light and all.  When I connected the second one upstairs, the main Extreme now shows amber on the Airport Utility.

 

Basically, I want to have a single network across the house and have 1 Extreme and 2 Express. Not sure if the question even makes sense, but hopefully someone will understand what I mean

    Will all of your AirPort base stations be interconnected by Ethernet or will they all be wireless?

     

    If they will be wired, check out the following Apple Support article on configuring all of your base stations for a roaming network.

     

    On the other hand, if the two Express base stations will have a wireless connection back to the Extreme, then use this Apple Support article instead.

     

    The clue for either configuration is that only the "main" base station, in this case your AirPort Extreme, requires that both NAT & DHCP be enabled. For the two Express base stations, these function need to be disabled. When disabled, the base station is acting in bridge mode. This will prevent the DHCP conflict you are currently seeing.

    Thanks Tesserax

     

    The Express would be wired from wall sockets, linked to the ISP modem. Right now, I think, I have it set up so the Extreme is the main, and Express are extensions or possibly named roaming.

     

    The issue is I'm useing airport utility, and do not have the same options that are on the your first link, for setting up a roaming network.  Having said that, both Express show up on the airport utility, and are green i.e. working fine, and are configured as Bridge Mode. So they're working fine, but the Extreme shows as amber on Airport Utility with the error "Conflicting DHCP Range"....

    ... but the Extreme shows as amber on Airport Utility with the error "Conflicting DHCP Range"....

    It sounds like your Extreme is not connected directly to a modem but to a combination modem & router. If that is the case the Extreme, too, must be reconfigured as a bridge along with both Express base stations.
