Hey everybody -

 

I just purchased an AC4000 to upgrade from the Airport Express I had been using.  I originally set it up as an access point, but then realized I wouldn't be able to use the QoS and other features, so I switched it over to wireless router mode, and that's where things got interesting.

 

My setup: ISP is Centurylink DSL; the DSL line goes into my network closest into a Zyxel C1100Z modem.  The LAN/WAN port of the modem goes to Trendnet TEGS80g unmanaged switch.  The various wired connections in my house go into a patch panel that then also connects to the TEGS80g.  The AC4000 is connected via its "internet" labeled port to a wall jack in a different room that then connects to the switch.

 

When I first set it up in wireless router mode, i made no changes to the modem, and my wired and wireless devices all worked, except I had two separate networks; the modem was providing 192.168.0.x addresses, the AC4000 192.168.1.x.  I then set the modem to transparent bridge mode, and this is the point where I lost all of my wired connections.  The AC4000 was providing 192.168.0.x addresses (with the AC4000 as 192.168.0.1, the same address the modem had been at)

 

Is this a cabling issue (i'll only get wired connections if I actually plug into the ethernet jacks of the AC4000), is this a DHCP range issue (i need to set the AC4000 DHCP range to something different than the router), or was I being an idiot and just needed to powercycle every wired connection?  I did DHCP renew a wired device and it didn't pull a new ethernet address in the correct range.

 

Thanks!

Turning your modem/router in a bridge then having that go to a switch was the issue. You need to have the modem/router which is now a modem go to a router first, then have a cable go from the router to the switch. Once you do that all devices will get an IP from the DHCP of the C4000.

Thanks, the more I've thought about it the more i've wondered if that was the issue. I'm going to have to investigate different placement or possibly a managed switch in the mix.
