Chromebooks and 3802 access points

[brene0001]

We've just completed some network up grades at four sites.  New switches and new access points.  The access points are 3802's.  The problem is some of our older Chromebooks no longer connect to the 3802's.  Swap out a 3802 for a 3702 and the Chromebook connects no problem.  WLC is 7400 and we're running 8.2.151.0.  It's kind of disappointing because we're talking hundreds of Chromebooks that no longer connect to the wireless.

Hi,

Please make sure we are not using any mixed auth also try to make use of wpa2 if possible. 

Also It is always advisable to upgrade the Chromebooks  driver to latest version.

Thanks

Google pushes automatic updates -

The Chromebooks work on 3702's, same switch, but they do not work on the 3802's at all.

Is channel 144 in use?

Remove channel 144 from the DCA list, this channel is not supported on Chromebooks. I am not sure if Chromebooks support channels 120, 124 and 128 as well.

For testing purposes, you may also try to statically assign the channel on a 3802, use channel 36 and 20Mhz of channel width.

The access point we are using for testing is set to channel 36 and 20 Mhz.   120, 124, 128, and 144 are not selected in the DCA list.   We upgraded the controller to 8.2.160.0 but still not luck with the older chromebooks.   This is becoming a major issue as well as frustration.  Your post is the only that actually had some thigs to try even though those channels were not selected in the list.  Thanks for response - still working with Cisco on the TAC case but I find it hard to believe we're the only school district having this issue.  Not looking too good for 3802's or wave 2 installations.

Did you ever get a fix to this? I am having this same issue right now

[brene0001 · Accepted solution]

It took a while - cisco actually sent engineers down to our site but what eventually fixed it was code upgrade - software version 8.3.130 on our controller.

Good to know, thank you for quick response!

[brene0001]

Good luck - we were frustrated for months.

sorry to post on this old thread, but was there a bug-ID for the original problem that we could look at?

wondering if we have the same problem, but we aren't able to update to the code on our WLC's due to the old AP's we have in some locations.

Can the ChromeBooks (CB) join if the the SSID is open authentication?
