I have a Cisco router 1941 connected to a switch. Im configuring the wlan-ap and i need to have the wireless devices have an ip in the same range of the wired devices. Since i cant use the same ip range on the gig0/1 and the Vlan 1 for the wireless, i wanted to know how to config the giga0/1 connected to the switch to act as a layer 2 port and i keep the ip on the vlan 1.
hi, as leolaohoo said you need to configure router on a stick. Also if it's a 1941 wireless router you need to configure a bridge interface on your router to make it works. Assuming you are connecting to the switch the port g0/1 of your router, you need to configure router interfaces in this way :
interface wlan-ap0 description Service module interface to manage the embedded AP ip unnumbered BVI1 arp timeout 0 no mop enabled no mop sysid no shutdown ! interface GigabitEthernet0/1 no ip address duplex auto speed auto no shutdown ! interface GigabitEthernet0/1.1 encapsulation dot1Q 1 native bridge-group 1 ! interface Wlan-GigabitEthernet0/0 description Internal switch interface connecting to the embedded AP switchport mode trunk no ip address ! interface Vlan1 no ip address bridge-group 1 no shutdown ! interface BVI1 description INSIDE LAN ip address no shutdown exit bridge 1 protocol ieee bridge 1 route ip
let me know if you need help to configure embedded ap. hope this helps. regards

Thanks, configuration seems logical. I tried it but didn't work. I should configure the switch port connected to the router as trunk or should i leave it access?
I could not ping ip address in the same range for PCs on the switch. The problem is that i don't have control on the switch. I will have to check with another team to make sure its trunk. I would expect that there is no configuration on the switch.
I will keep you posted. Appreciate the assistance.
As suspected switch configuration. Once i changed the port to trunk things went fine. Everything was reachable. Once thing to mention is the DHCP. I have dhcp server in the same range but the wireless devices couldnt get an ip from it. I had to put ip helper address on the BVI interface of the AP To fix it.
