No network connection btw WLC and access points

Unanswered Question
Nov 16th, 2009

Hi,

There is no L3 network connection to some of the 1522 APs in our mesh network.

They register with the 4402 WLC (5.2.157.0)i.e. appear in the AP list. When sending ping packet to APs IP addresses from WLC or PC there is no response, but I can see APs MAC addreess with "arp" command. Users connected to these APs can not access wired network, also in Monitor -> Current clients -> Detail "Auth" is Yes for users who can access wired network and No for those who can not.

Any advice would be appreciated.

TIA.

I have this problem too.

Today I found out that AP-15 in the following mesh configuration  was the source of the problem:
No network connection to AP-15 and it's child APs (AP-19, A-17, B-18, B-14,A-16),
when testing links with "child" (AP-19) and "parent"(AP-21) APs "Error: Cannot get
stats from the destination ap" message but it sends and receives packets to and
from other neighbor APs.

After Hardware Reset on WLC web interface AP-15 functions normally.

Here is the mesh configuration:

=======================================================
||  AP Name [Hop Counter, Link SNR, Bridge Group Name] ||
=======================================================

[Sector 1]
----------
Central_AP-10[0,0,default]
  |-AP-21[1,42,default]
    |-AP-15[2,31,default]
      |-AP-19[3,39,default]
        |-A-17[4,37,default]
        |-B-18[4,40,default]
        |-B-14[4,39,default]
          |-A-16[5,31,default]
    |-AP-22[2,22,default]
  |-AP_02-12[1,26,default]
    |-AP_03-20[2,39,default]

----------------------------------------------------
Number of Mesh APs............................... 11
Number of RAPs................................... 1
