DHCP not giving IP's to wireless clients

Xintruder

Level 1

Hello,

I am configuring an 877w router.

I have configured my DHCP pool, no problems. I tested it using my local LAn, all clients are getting the ip's from the pool I specified.

However, when I scan and try to connect to my SSID, it starts connecteing 'forever' and states a problem: my client can't get an IP lease from my DHCP server. When I give my Windows XP box an available ip from the same NAT pool, it connects to the network, but it can't ping my gateway (although its setup..). I also can't access any network recources. I can ping my loopback IP and my local setup IP.

I'm kind of, lost at the moment.

Normally, this 169.x.x.x ip address is shown when the AP is not able to get an IP address from a DHCp server. So, check whether a DHCP server is available to provide Ip address and properly configured. Else, configure a static ip address to the AP.

I'm not sure what you're trying to do here.

You're wired LAN is probably getting the addresses from network 10.99.99.64 255.255.255.192 due to being in VLAN 1.

If you want the wireless to get addresses from the same pool, you would need to change the encapsulation on interface Dot11Radio0.2 to 'dot1q 1 native', and get rid of the ip address.

If you're wanting a seperate pool, you'll need to create the second dhcp pool, create vlan 2, and create bvi2. You'd want to put the ip address of 192.168.0.1 on interface bvi2.
