DHCP not working on Cisco 877W

Question:

I have a Cisco 877W in WS-C3560X-48PF-S place with an ADSL connection, which is working fine.  However I cannot get it to hand out a DHCP address.  If I associate with the AP over wireless then set a static IP I have full connectivity, similarly if I connect over Eth0 and set a static IP I have full connectivity.  So it does just seem to be DHCP.  Below shows my config... Any thoughts on the issue?  Is it access-list related?

I have checked with Wireshark and I see the DHCP request being sent out, but I don't see a DHCP offer being returned

Thanks

Answer:

There is a typo in the network- IP-address: 169 instead of 168:

ip dhcp pool home
   network 192.169.99.0 255.255.255.0
