DHCP Server problems with Access Points
We currently have 13 Access Points controlled by a Cisco WLC 2504. We have two WLans - one for Guest and one for employees. Our employees use WLan 1 which accesses the DHCP server on my domain. The Guest uses WLAN 2 which access the DHCP on my router. On my DHCP server we have two separate subnets with plenty of IP's available. Due to some routing issues, I needed to use most of the available IP's for phones. Once that was cleared up, those IP's are now free again. My problem is that we are now unable to get an IPV4 address from the employee access point. We have two subnets, so there are plenty. What do I need to do to fix this issue. Interesting enough when I create a separate vlan pn my router, any device connected to the employee access points gives me the error message - no internet access

Make sure that the vlan interface on your wireless controller has the dhcp server setup correctly on it.

The lease period is 6 hours. My phones were on a Vlan and used their own DHCP from my router. I had to take them off the vlan to fix an issue. After the problem was fixed I put them back on their vlan that is when I started having an issue with my employees wireless. Nothing was changed in the WLC at all. The IPs on the guest wi fi are from the router they are on a separate vlan also.
I went into the main DHCP server and deleted those devices from the server.

Is the vlan config for the quest wifiidentical to what it was before, or has it changed. Double check the subnet mask for your segment is correct.

It is the same. The guest wi if works perfect.

Im assuming that the AP gives an ip after authenticating.
ASKER
They are authenticated using a WEP/WPA. I did do that and my employees wi fi did not work. The computer connects to the wi fi but won’t connect to the internet
ASKER
Yes it does.

Thank you. I have left the office and I will try this on Monday.

I think I have figured it out. My DHCP server has 2 scopes and my information for the employee wireless points at the main DHCP server gateway and not the gateway for the other subnet. I think I just need to add that gateway to the DHCP configuration for the employee wireless also. I think when the main subnet ips are all used the wireless has no ips to pull.

Over the weekend after all the IP's were cleared, my employee AP's were able to connect and my devices are now connecting to both subnets with no problem.
Very good.
