Cannot Access WLC While Connected Wirelessly

[Matthew Martin]

Hello All,

2504-WLC: Software Version 8.3.132.0

I am unable to access the WLC's Web GUI or Telnet/SSH while my laptop is connected to the Wi-Fi.

I have the option "Enable Controller Management to be accessible from Wireless Clients" checked under Management > Mgmt Via Wireless. But, I am still unable to reach the WLC on Wi-Fi.

Any ideas?

EDIT: Maybe this is why? https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvh32971/?rfs=iqvred

Thanks,

Matt

You can verify that, if you can upgrade your WLC to a later code that got a fix for it.

I would suggest 8.5.130.0 (hopefully it will come within next week or so)

Hey Rasika, thanks for the reply!

Ok thanks. Would you be able to supply a link to the upgrade process for the WLC/APs? Its been a while since I've had to do it.

I think I remember there being a way to pre-load the new image onto the APs before rebooting them for the upgrade. Is that right?

We have:
2504 WLC
AIR-CAP2602I-A-K9
AIR-LAP1142N-A-K9
AIR-CAP2702E-A-K9
AIR-AP2702I-UXK9

You should always follow the release notes for the software, it includes the upgrade steps. Also, always check the Wireless Software Compatibility Matrix prior to any upgrades - https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html.

The last supported version of AireOS for the 1142 is 8.3.x.

Pre-download steps are also documented, https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-3/config-guide/b_cg83/b_cg83_chapter_0101.html#ID1225.

To do the pre-download, its pretty easy. Once you've got the new image transferred onto the WLC - you can use the following command to start the pre-download (CLI):

config ap image predownload

And to verify that all the APs have the new image, use the following command:

show ap image all

Thanks for the info Evan.

Looks like I need to replace a few Access Points in our building before I can upgrade the controller. It looks like our WLC is currently on the newest supported version for a couple of our 1142 APs.

Thanks for the info all, and I guess after I get those APs swapped out I can upgrade the WLC.

Thanks Again,
Matt
