Wireless DHCP

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

Re: Wireless DHCP

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.

Re: Wireless DHCP

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

Re: Wireless DHCP

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