Cisco AIR-1141-E-k9 access points

mohammed samiuddin · ‎03-01-2014

Hi,

Facing an issue with 1141. Not sure if it is from AP or from the Laptops!

Problem is when some users are trying to connect their laptops to wireless it shows Limited connectivity and didnt take an IP address. But with some users its obsolutly working fine.

I'm facing this issue only at one of the site. We have other sites working fine without any interruptions.

Checked the security:

Using WPA/TKIP

Cisco IOS Software, C1140 Software (C1140-K9W7-M), Version 12.4(25d)JA, RELEASE SOFTWARE (fc1)

Couple things to try is delete to profile and create it again and maybe look at the driver version.

Was this always working and then it just stopped or was this new? You have enough available DHCP address?

Hello Scott,

It happens once a week. We have suffecient DHCP IP address in pool.

It happens every week to fix this temporrarly we have to restart the DHCP (router 881) and access switches then it preemt the state.

Let me brief ma scenerio:

Router 881 ( DHCP server ) vlan 14 ---- Access switch 2960 ---- AIR-1141 access point --- clients (Laptops)

#switchport is configure as vlan 14.

#Access point mgmt IP configured in vln14 range . And it is accociated in access point vlan1 (Native).

May be you can reset AP or just power off and on it again.

Tried couple of times, still the same.

Let me brief ma scenerio:

Router 881 ( DHCP server ) vlan 14 ---- Access switch 2960 ---- AIR-1141 access point --- clients (Laptops)

#switchport is configure as vlan 14.

#Access point mgmt IP configured in vln14 range . And it is accociated in access point vlan1 (Native).

If clients can't get IP Address from DHCP then on the 881 router, post the output to the command "sh ip dhcp bind". Also post your DHCP config. I'm suspecting that your DHCP pool has a high lease time and you have DHCP starvation.

I would also see if just disabling the DHCP pool and enabling it fixes it whiteout rebooting the router or switches. Try to isolate the issue, but I bet it's the router.
