Wireless DHCP

[nicholas.vanbussel]

Hi, I am trying to get my 870 router to assign DHCP addresses to wireless clients. The wired LAN works fine. If I assign a static address to my laptop it seems to work fine. Just not DHCP.

I have posted my config.....

Any comments appreciated

Nicholas, the problem I see is that you are using a second vlan, and you do not have it defined in the router. Try this:

interface Dot11Radio0

no ip address

!

encryption vlan 2 mode ciphers tkip

!

ssid Home

vlan 2

authentication open

authentication key-management wpa

wpa-psk ascii xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

!

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

station-role root

bridge-group 1

bridge-group 1 subscriber-loop-control

bridge-group 1 spanning-disabled

bridge-group 1 block-unknown-source

no bridge-group 1 source-learning

no bridge-group 1 unicast-flooding

!

interface Vlan2

description Wireless

no ip address

bridge-group 1

!

interface BVI1

ip address 10.252.12.1 255.255.255.0

ip nat inside

ip virtual-reassembly

!

Added a VLAN2 interface that is in bridge group 1, and set the SSID to be in vlan 2, also changed the encryption command to encrypt vlan 2.

In the conf mode on router run the is helper command & give the ip address of the dhcp server.

You should remove "ip nat inside" from vlan 1 config and put "bridge-group 1" under vlan 1 config.
