Installing AP in office

Hello!

We have cisco 1941 as router in office, it's dhcp server, it has only vlan 1 192.168.4.0/24

I've set up 1142 ap for wireless clients

How can i make it give clients ips from dhcp server from vlan 1 ?

When using wpa2 you need to use aes. If you use WPA them its TKIP.

The bvi will get an IP address on Vlan 1 and so will your clients. The config looks fine other than what I told you to change.

Re: Installing AP in office

If your 1941 is the dhcp, just create an SSID and place it on Vlan 1. That should be it.

Re: Installing AP in office

thank you, windows clients will authenticate without problems?

do i have to make configuration of gigabit ethernet, i couldn't get it why bvi 1 interface gets ip from dhcp but not gig 0

will this configuration provide ip to clients from 1941 dhcp server?

Installing AP in office

Hi Greg,

Please be aware that AP is not a router..It is a bridge and does not use ip address on Gig0. Any traffic the AP gets on the radio interface (dot0) and physical interface (Gig0) are bridged to the BVI interface and are send to the rest of the network. So only BVI interface will have ip address on an AP.

Yes with the above configuration your wireless clients should gert dhcp ip address from 1941 provided the AP and router can reach each other.

Hope this helps.

Regards

Najaf
