We have a 10,000-seat sports arena with 120 APs in the arena, 277 APs total in the whole building. Currently, all APs are in a single site tag and therefore on a single WNCD process. WLC is a 9800-80 on 17.12.4/APSP6 with 2,200 APs joined.During a so...

I'm trying to copy configuration that contains encrypted passwords from one 9800 WLC to another. The key that was used when encryption was originally setup are unknown. Is there a way to view the key that was used? I read elsewhere that it's stored i...

EoL announcement recently posted for the 9800-40 and 9800-80 WLCs specifically:https://www.cisco.com/c/en/us/products/collateral/wireless/catalyst-9800-series-wireless-controllers/catalyst-c9800-wireless-lan-controller-eol.htmlI've been wondering whe...

Posting this here as an FYI: https://bst.cloudapps.cisco.com/bugsearch/bug/CSCwm31864The symptom we've seen is clients unable to connect to a specific AP, so they connect to faraway APs instead, or their connection drops when they attempt to roam to ...

While attempting to work around a different issue, I realized that the XOR Slot 2 radios in Cisco 9166s provide very slow throughput when in 5GHz mode when they've been up for a time. Throughput is as low as 30Mbps up and down in an empty room with a...

When we cut over our first building from 8540s to 9800s two years ago, we had a small percentage of devices that had issues connecting (I forget the exact symptoms/error messages), but the solution was checking of the "802.1x" AKM in addition to "FT ...

What's different about the APs that are offline vs. online? Are they a different model then the others? Are they in a different VLAN/subnet? Are they connected to a different access layer switch and/or a different distribution switch/router? Check in...

What software version is the 2504 running and what model of APs are in use?

Without a mobility group, there is no fast roaming, it turns into a full disassociate from the source AP then associate to the destination AP. At least, it does with 802.1x. Not sure about PSK or open networks, but I believe it's the same thing, just...

The bug is reportedly resolved in 17.12.5 and 17.15.3. For various reasons we will not be upgrading to either release in the near future, but for now I'll mark this as the solution.
