Wireless configuration help with cisco 861w

I have no problems setting up the router without wireless, however my lack of knowledge with the built in AP is driving me crazy!!!! I have tried to follow 871w configs but none of that seemed to work.

My goal is to have the wireless clients on a separate vlan
wired host vlan 100 172.16.1.0/24
wireless clients vlan 601 172.16.16/24

This AP supports G/N clients and I have not seen any documentation on how to specify G only for
instance.

I don't need to preserve any configurations as this is a lab environment.

Thanks lrmoor, I will give that a shot.

I do have a question in regards to the BVI setup in respect to the VLANS, does the BVI group have to match the VLAN ID? or is this more of an arbitrary assignment like a subinterface id?
The BVI number matches the bridge group number not the vlan, but in this case the vlan ID matches the subinterface which matches the bvi, which matches the bridge group, etc.. just good practice to keep them all in sync for ease of troubleshooting later.
Are you using the Cisco software that came with it to configure it? The Cisco Configuration Professional?
It has quirks of its own...
Thanks for the config, I had it working to a point.

I'm running into issues modifying it to fit my topology, and suspect that the more I hack at this the deeper my hole is getting.








config-posted.txt
>I had it working to a point
You gotta be more specific than that...
what works, what doesn't?
sorry, I should have been more specific.

Using your configuration I was able to connect via wireless to the 10.1.10.x net (I think you had that listed as corp) when I started to modify the config for my specific networks it stopped working.

Using your config the AP was pulling a 10.1.10.34 address and I was able to connect to the AP web administration site.

As configured now, the AP is not pulling an IP and when I connect to the HOME network its trying to connect but stays at waiting for network.

I suspect the issue is somewhere in the vlan, bridge-group portion of the config.
Ok a small update

I just entered some configuration into interface vlan 1 on the router, setup a DHCP scope for it, and the AP interface BVI 1 pulled an IP from that.
I recreated vlan 1 on the GigE and Dot11radio interfaces and set the vlan to native. and I am now able to connect to the test network on vlan 1.

I'm still unable to connect to vlan 601 ssid home for some reason.
Looks like this router is restricted to only having 2 vlan's. vlan 601 was showing protocol down, I'm not sure if it was showing that way all the time, or if it went down after I reconfigured vlan 1.

Either way I have decided to modify my original intent. I will assign wireless clients to vlan1 instead of 601, I'm disappointed that after all this messing around my problem was most likely caused by my desire to avoid using vlan1 as this note I found in a config doc would indicate.

Note: When you configure VLANs on access points, the Native VLAN must be VLAN1. In a single architecture, client traffic received by the access point is tunneled through an IP-GRE tunnel, which is established on the access points Ethernet interface native VLAN. Because of the IP-GRE tunnel, some users may confgure another switch port as VLAN1. This misconfiguration causes errors on the switch port.

Before you give up, you can try setting interface interface Wlan-GigabitEthernet0 to a trunk port
 interface Wlan-GigabitEthernet0
   switch mode trunk
I appreciate the added suggestion, but while I know how to set the interface to trunk mode, I not sure how this will help me. Could you provide your thought process on that?
That interface needs to trunk multiple vlans to the AP. If you don't, you'll probably see the vlan interface up/down. because there is nothing active on the vlan.

My early testing of the config I posted gave me a false positive. I was not actually getting an IP address from the correct address pool when connecting to HOME on VLAN3, and the vlan3 interface showed up/down. I plugged into one of the vlan3 switch ports and I got the right IP address and brought vlan3 up/up. It works now and I did two things.
1. define the vlan on the router (should not have had to do this because I used CCP to do the initial config)
  router(config)#vlan 3
  router(config-vlan)#exit

2. Set interface to trunk port

BAM! I started getting the appropriate address from vlan3 dhcp pool on HOME SSID. I think that setting the interface to trunk mode keeps vlan other than 1 up/up


 
I see

while doing this did in fact bring my vlan 601 up/up I don't think the router is happy with my third vlan. Still unable to ping the vlan interface IP address.

I will need to do some testing with vlan 100 to see if I can pull the proper IP via wireless should I choose to setup wireless access for it.

However for the time being my wireless clients are able to access vlan 1 with no issues. So I will conside this question closed for the moment.

Thank you for your time.
