Help me understand thie odd DHCP behavior
My network has about 15 devices on it (network A), half of them wired. I added an Ubiquiti AP out in my yard set to WDS repeater mode. I bridged to another old router in a building 300 feet away to...
OK, so it was explained to me that when a device accesses the network, it takes the first DHCP offered to it. In this case the AP on Network B was reaching back through the bridge to assign IPs before the R6400 could respond. I didn't know it could do that.Silly me, I thought it would only assign them on Network B, where it was set up as the AP.
The solution was to turn off DHCP on network B, and let the R6400 assign the IPs on both networks. I didn't know it could work that way, either!
Hi artworksmetal,
That is indeed a strange behavior since the router should assign IP addresses within the DHCP pool. You can either set static IP addresses to your devices or connect all the devices to network A first then do Address Reservation and do the same for the devices that will connect to network B.

Hi artworksmetal,
Thank you for the confirmation. Glad to know it is working to your preference now.
