Cisco Arionet 1200 AP in Bridge mode

[Staapaavandski]

I have these two LinkSys AP that run in Wireless bridge mode, but they run very unstable, and I want to get it as close at 100% stable as possible. So I have bougth these two Cisco Arionet 1200 AP (AIR-AP1231G-E-K9) which I want to get to run in Wireless Bridge mode.
But I cant get access to the browser GUI, because when I plug the Lan cable in the "Ethernet" port and the Lan port on my PC the connection is not ok. And I don't know the static IP (if there is one).
I'v made a Serial to lan cable, so I can access the AP via the "Console" port, and it works, I'v tryed some codes, like:

enable
conf t

then
ip http server

But I still cant get access to the GUI.
Could you guys perehaps guide me? If you need to know more, just ask :)

I used the ip address "ip" "mask" command

If the device is running reverse ARP, you can ping the mac address that should be written on the back of the device. If that doesn't work you can just reset the device to factory default and start from scratch.

If you are connecting directly from the AP to your laptop you will need an Ethernet Crossover Cable since each end is paired the same (normally crossover happens at the switch).

Try that to get the GUI.

Also from the Con port log on and do a "sho run" to list the config of the AP and therefore determine the IP address.

When you console in to it and it asks you for a password your password should be Cisco by default.

if you need to set the ip address

enable
config t
int fa0 (if using vlans I think is will be int fa0.vlan#)
Ip address x.x.x.x 255.255.255.x

Place computer in same LAN, connect to it via HTTP(S).
