The bug for CSCwi92439 is also resolved in an AireOS escalation build, 8.10.190.8. I contacted TAC to obtain that version and they sent me 8.10.190.9 instead since .8 was "retired". From its release notes, here's a list of the 8.10.190.x escalation builds and their resolved bugs if anyone's interested. ...

Update on the MacBook issue. I worked with TAC to try to do further debugging in late January, however, we could not reproduce the issue. Two things had changed since previous troubleshooting: macOS went from 13.5.2 to 13.6.3 and we updated the WLCs from 17.9.4 to 17.9.4a with APSP8. It doesn't look ...

Over time, I have found a few more rooms affected by this issue, including one that has 9130E access points rather than 9166I. The 9130Es are on a different 9800 WLC that's on the same code and config as the one the 9166s are on. This is the only large room we have that has 9130s rather than older APs ...

Thanks, Larry. I'm not doing that now, but that's good information to have. Out of curiosity, were you using option 3 or option 4 from that guide? Jason, the exact version these APs are running is 17.9.4..208 (that is AP service pack 8; we also have 3702s, but the APSP doesn't apply to them, so ...

Our Facilities department is evaluating Airia – SAS that provides AI-driven facility analytics – and has reached out to us for network and SSO-related information. I have attached their IT deployment package PDF, which includes the introduction below. (EDIT: Attachment removed at Airia's request.) Is ...

Hi fellow Cisco shops, I have another weird issue I'm wondering if any of you are experiencing. We received reports of slowness/lack of connectivity in one of our lecture halls with 9166 APs running 17.9.4a with APSP8. Every single client in the room was connected at 2.4 GHz and channel utilization ...

I'm interested in seeing the responses to this, especially given the current lack of 6 GHz hospitality APs on the market (as far as I'm aware). Is that a factor in anyone's planning? Eric Glinsky Wireless Service Manager University of Connecticut eg@uconn.edu

Our Palo Alto border firewall does what limited NAT we use here – mainly WiFi clients, since most wired clients get public IPs. Some special networks such as PCI had NAT through our FortiGate department firewall, but those are getting migrated to the Palo also. Eric Glinsky Wireless Service Manager ...

With the announcement that HPE is to acquire Juniper (which has been shared and discussed on NETMAN), I'm curious if anyone's using an enterprise WiFi manufacturer besides HPE/Aruba/Mist or Cisco/Meraki and how pleased you are with their products. We had a sales pitch from Arista (Mojo/AirTight) ...

Regarding some MacBooks not passing traffic on 9166s with the WPA3-SAE SSID broadcasting, TAC blames Apple. If anyone's interested in looking at their full analysis of the packet captures, PM me and I can send them. Long story short, "...the packet [continuous ping to default gateway] with sequence 39 ...

1 confirmed issue here, resolved by uninstalling KB5033375. They did not have KB5032288 installed. Thanks to this community and this discussion, I saved a lot of troubleshooting time. We're a Cisco shop and they reported the issue in a res hall on 8.10.185.3 and an academic building on 17.9.4. The ...

I was wondering if anyone experiencing either issue in this thread have had any breakthroughs. No further complaints here after raising the power levels on the 1815s in that apartment complex. This thread on the Cisco forums was interesting: https://community.cisco.com/t5/wireless/poor-5 ...

It will be interesting to see if Hamina ends up making any accommodations for EDU or customers in general that have multiple individuals doing design and/or survey work. Although, since the survey and design licenses are separate, maybe that's less of an issue than it was for Ekahau. My dissatisfaction ...

For those of you who go by number of users per radio, does different hardware capability factor into that number? For example, would you change the number of users per radio depending on if the radio is 2x2, 4x4, or 8x8? If you have APs where you can choose either a single 8x8 or dual 4x4 5 GHz radios, ...

I think the study/hangout areas will have less demand on an AP for a given number of clients than the classrooms will. In theory, classrooms are more likely to have bursts of high traffic on many clients simultaneously when they do an online activity, such as an exam (which could include video clips), ...

We had AirMagnet for years but switched to Ekahau a couple years ago. That seems to be most prevalent in the industry and we want to be able to view project files from consultants we hire to design/survey. I only used AirMagnet a handful of times for surveying, but found Ekahau much more intuitive. ...

Thank you, Jeff. The bug that that APSP fixes is about a crash. There are half a dozen related bugs to that one (scroll down in the BST) and they are all about kernel panic/crashes. I guess that makes sense for connection drops, but I hardly see any crash logs on the 8540 WLCs currently. Disappointingly, ...
