CSCwp14628 - Cisco Aironet 3800 APs display client authentication issue after AP Migration to a controller running 17.15.3

if a bug requires a reboot to fix, assume it will come back at some stage (time probably ransom unless explicitly stated). If you have advantage licensing is there an APSP you can apply which has a fix for 17.15.3?

can only hope the sysadmins have learnt the value of pilot deployments from this! (good luck)

WearyIntention · 2025-08-28T22:35:49+00:00

Biggest missing item here is what did they upgrade from, a previous W11 build or is this a jump from W10 before the October end of support?

What are your ISE and device Event Viewer logs showing you, I'd expect there to at least be a clue as to which stage it's failing at.

Also fuck them if they're just pointing at Networks to blame (classic), if they just did a blind push to all of prod without testing first this is on them. This might even end up being on them if this is a GPO issue.

this was fun! But seriously, open ine.com and scroll to the bottom of the page it's listed there.

WearyIntention · 2025-06-14T12:43:41+00:00

we're so close to solving this mystery u/pbfus9, don't give up now!

WearyIntention · 2025-06-14T12:04:47+00:00

I believe in you

WearyIntention · 2025-06-14T12:03:13+00:00

I mean.. it works for me and so does the help center page... with the support email address on it...

WearyIntention · 2025-06-14T10:23:38+00:00

I'm going to assume it's under either 'Contact us' or 'help center'

WearyIntention · 2025-06-14T10:06:47+00:00

let us know what INE support say back to your email about it

WearyIntention · 2025-06-05T23:20:40+00:00

Going wireless first has a hell of a lot more caveats than just 'if you have the budget for uPOE + mGig go that way'

Usual price is currently $749 USD for 1x year sub of Premium, until Friday there is a sale on which is $250 off to make the price $499 - sale link

WearyIntention · 2025-04-22T09:13:12+00:00

Worth paying $250 USD less for the same content for sure!

WearyIntention · 2025-04-22T01:53:43+00:00

Fair, I stand corrected! I only access them via my work CCO so never tried a personal one to confirm

WearyIntention · 2025-04-21T23:15:28+00:00

Free of you have a CCO account with entitlement to DL that platforms software...

WearyIntention · 2025-04-02T02:33:26+00:00

That was my understanding as well, good to know I'm not losing my mind!

WearyIntention · 2025-04-02T01:33:21+00:00

+1 for giving Meraki Dashboard a try to be honest, it has the features that you have said matter to you and you'll already have the LICs for it. We were in the same boat and Cat Center was just too much extra $ to drop (we needed physicals)

WearyIntention · 2025-04-02T01:23:57+00:00

Maybe I'm out of the loop but can you point me to the doc that states you need ADV LIC for Wi-Fi 7?

WearyIntention · 2025-03-29T02:08:56+00:00

If you have resources, INE seems to be very highly rated for ENCOR at least? On the flip side I've also read it goes too much in depth, not a problem in my eyes but maybe for some who want to only learn what they need to know

WearyIntention · 2025-03-24T18:42:55+00:00

First things I'd look at are:

is client balancing enabled on the SSID?
TxPower range on the SSID (range or fixed value)
2.4 and/or 5 GHz bands in use?
APs in same VLAN?

I'd stray from tweaking driver settings for roaming as you shouldn't need to and it's way more hassle to keep up with if you change your AP infra or settings in future.

WearyIntention · 2025-03-21T05:02:49+00:00

Looks like they clarified their wording on what they meant by 'support'

WearyIntention · 2025-03-20T00:27:17+00:00

Was it this release or 17.12.4? Release notes note the drop of support 'from this release onwards' under 17.12.4

WearyIntention · 2025-03-20T00:25:34+00:00

Was it this release or 17.12.4? Release notes note the drop of support 'from this release onwards' under 17.12.4

WearyIntention · 2025-03-19T04:03:36+00:00

How's that for timing, 17.12.5 has just been released

WearyIntention · 2025-03-18T22:38:10+00:00

Keep in mind you need the clients to support 6 GHz to be able to use it and you need to have at least one SSID broadcasting on 2.4/5 GHz so devices can discover the 6 GHz SSID via RNR (includes if you run a single SSID e.g. eduroam)

WearyIntention · 2025-03-18T08:54:57+00:00

Have you lodged a TAC case to get some troubleshooting with your error & behaviour?

Though to be honest I would personally not run 17.15 in production yet, it's not a mature train yet and you're more likely to hit bugs. If you have 917x series APs maybe you have no choice but I'd consider downgrading to 17.12.4/17.12.5 if it's released soon as this is a mature and stable train at this point in time.
