some DHCP problems

[att-sgcops]

I have an existing DHCP servers in the network which assign IP from 10.1.1.0/24 pool. Now I have new AP for wireless use. I also configured AP as DHCP server to assign 20.1.1.0/24 pool. Since AP and existing are in the same network (connecting via switch), when use connected via wireless, they sometimes got 10.1.1.x/24 instead of 20.1.1.x/24, how can I solve the problem?

thanks

Configure the ip helper address in the AP that should resolve the problem.

Do you mean you want to assign IP for wireless user from AP and wired user from existing DHCP server ?

In this case, you may need to segment the traffic to two VLANs, one for wired and one for wireless. Due to there are two subnets, I expect you have somewhere to route the traffic for these subnets. So implement VLAN will solve it. However, if the device cannot route VLAN, you may consider to route through two individual interfaces but still setup two VLANs in the switche but not enable trunking to the router.

If this can't solve the problem or it is the case, please advise more details of your current network design.

Hope this helps.
