I have a WRT610n running DDWRT v24-sp2. My goal is to setup:

  1. Single connection from switch to WRT610n, and switch passes tagged VLAN 50/40 and 1 (untagged)
  2. On WRT610n the 3 LAN ports (eth1/2/3) and 1 WAN port are disabled.
  3. The wrt610n is to act as an AP
  4. There should be no traffic passed between VLANS on the WRT610n (that will be the job of my seperate switch/router) 5. There should be 3 WLANs on the AP:
    • Radio 0 SSID "A" (mapped to VLAN 1 / no tagging)
    • Radio 0 SSID "B" (mapped to VLAN 40)
    • Radio 1 SSID "C" (mapped to VLAN 50)

I've gotten part of the way there, but the docs are so old (and contradictory at points) I'm not sure where to go next! (I also don't understand the role of the bridges, and setting bridged/unbridged on the basics settings page). So I have:

  1. Created wl0 as SSID A
  2. Created wl0.1 as SSID B (virtual interface)
  3. Created wl1 as SSID C

and all are marked as "bridged" in the basic settings page. I have disabled the WAN and ETH1/2/3 leaving only eth0 as my LAN connection.

Now what? Do I switch to unbridged and then create bridges? If so, my options for assigning interfaces (to bridges) are: eth0/eth1/eth2/etherip0/eth0.0/vlan1/vlan2/wl0.1 but I don't even know what these mean! (where did eth1/eth2 come from,etc)

SOOOO confused. Appreciate any help!

See here for how to have a single radio operate on more than one VLAN. Also, you realize that one radio is 2.4GHz and one radio is 5GHz, so at least one VLAN will only be accessible on 5GHz. (Unless you create three networks on each radio.) – David Schwartz Jul 20 '12 at 23:27
I tried that page but several problems: 1. That doc says to leave the wlans bridged because of bugs in svn 13312, but my version is now 14896. Do I leave them bridged? 2. In the bridging section, the doc says add bridges which ask for IP addr/netmask etc but I don't want to add IP's to that subnet - why do I need them? The AP should not be routing, that's the job of my switch. – Michelle Jul 20 '12 at 23:52
1) If you have to leave them bridged, your design won't work. 2) I'm not sure what purpose that IP information would serve. You're just bridging, which is not an IP-layer thing anyway. Get the WLANs in the correct VLANs first. – David Schwartz Jul 20 '12 at 23:55
Ok - I switched each WLAN into unbridged mode. Now it asks me for an IP/NETMASK at the basic settings page for each WLAN. Why is it doing this? I agree that it should be operating at layer 2. So what do I do? – Michelle Jul 21 '12 at 0:06
You may need to set them into bridged mode. I don't remember ddwrt's configuration specifically, but in unbridged mode, it may assume they're end IP interfaces. In bridged mode, hopefully, it will allow you to assign them to a bridge (which is what you want to do, you want to bridge them to the VLANs). It will probably initially put them all in the same VLAN, but you should be able to change that. – David Schwartz Jul 21 '12 at 0:10
