Problem with Cisco Aironet 1100

[ter79]

My company has just installed a Cisco Aironet 1100 Access Point. I have a laptop with a DLink AirPlus Wireless Card. I can connect to the Access Point but I'm getting an IP address from the AP, therefore unable to access network resources or get out to the internet. I'm new to Cisco so is there anything I need to look for in the configuration settings that would solve this problem.

Thanks in advance

you need to setup bridging between the ethernet port and dot11radio interface on the 1100 ap. Make sure that both the ethernet interface and the radio interface are both in the same bridge-group.


Here is what my setup looks like on a 1400 series.

interface Dot11Radio0
no ip address
no ip route-cache
!
ssid xxxxxxxxxxxxxxxxx
authentication open
guest-mode

!
speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
rts threshold 2312
station-role root
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding

interface FastEthernet0
no ip address
no ip route-cache
duplex auto
speed auto
bridge-group 1
no bridge-group 1 source-learning
bridge-group 1 spanning-disabled
end

interface BVI1 (this is the management interface. # specifies the bridge-group)
ip address x.x.x.x 255.255.255.0
no ip route-cache
end


Hope this helps.

You will also need to disable the DHCP features on the AP1100 so that it doesnt give out dhcp. With bridging enabled your dhcp requests will pass throught the wireless onto the wired network and hit your dhcp server which will give you what you need to access the internet/network. hope this helps.

Hi,

I was having the same problem with you before. The solution was to upgrade the IOS of the Access Point. It must at least 12.2(13)JA3. You can download it from Cisco website.

I have upgraded to the latest version of IOS and still no luck. I'm working with Cisco TAC on the issue but to no avail at this time.

Have you actually seen yourself associate to the AP? How do you authenticate?

I have a number of 1100's in stores and warehouses. We get DHCP addys thru our server here at the data center. If you're able to pull an address ona workstation on the LAN that the AP's hang off, then you're clients should be able to as well.

The AP dosen't act as a DHCP server, its only a client, so Im guessing your first post said, that you were NOT getting an address. Bridging is turned on by default in the IOS so unless you turned it off, that should not be your problem.

What Aironet extensions have you turned on?

Definitely agree on The IOS being at (13), fixed ALOT for me, roaming issues and dropped sessions by the guns.
