RE: Strange Traffic Spikes

Those traffic spikes might be false [if not seeing anything correlating from packet-captures or other monitoring services]. Are you seeing any process restarts in "System – Event Log" or any correlating statistics in "System – Performance Monitor" such as "RabbitMQ Depth Delay"? We're seeing something ...

Managing Capacity Expectations of Outdoor Wi-Fi

Just curious how other universities attempt to handle managing of expectations of Outdoor Wi-Fi. 😊We've had a good deployment over the past 10 years – tripling our outdoor coverage throughout our campus with positive results in green/casual areas of campus. Expanding Wi-Fi down center of our Quad ...

RE: Cluster Instability - Non-Responsive Controllers - ArubaOS 8.10.0.5

Kameron, Very interesting indeed! Thank you for sharing. That's about our environment as well – 7240XM four node cluster with 3600 access points in our case. Neither controller was able to generate crashinfo in our cases – 2nd down controller never could get console working – not even briefly. ...

Cluster Instability - Non-Responsive Controllers - ArubaOS 8.10.0.5

Slight duplicate from the "Cluster instability running Aruba 8.10.0.4" – but no activity since August 2023. Was curious how everyone's clusters have been behaving and what code. After about 1.25 years on 8.10.0.5, we've had two cluster failure events with 2 of our 4 7240XM controllers. The instability ...

Matthew, That issue sounds very similar to what we ran into last July. Two 7210 Gateways with auto-cluster – 10.4.0.1_10.4.0.2_87241 – during a "test upgrade" – one of the controllers didn't "auto-reboot" – and had to manually force a reboot. Gateways came back up and everything appeared good. However, ...

Thanks for the info Derrick. Was not aware of their shenanigans of removing support – and that Automotive VR sounds pretty cool! Patrick, we never did find a better solution beyond just the two dedicated Chromecasts with Oculus VR – pretty much all quiet after we got them up and running after some ...

Good Morning, Anyone have any experience with Ultimate Drill Book and Beam app by UDB? �� Been asked to provide Wi-Fi to a parking lot for over 400 Band Students next year. Already looking at Private LTE and Wi-Fi Options [have concerns since we'd have to use DFS Channels – and we seem to get some ...

Erik, That definitely helps and appreciate it! A lot more information than I had before. I was a bit afraid of that "roaming"/"band-locked behavior" – and suspected if that might be the case. The night I first started working with the student, I kicked the client from the network just to trigger ...

RE: Encryption for Guest/IoT Networks

Found In Egroup: Wireless Local Area Networking \ view thread
A couple other factors to throw in the mix. Not all IoT Devices will connect to an open network. Some require a PSK network as part of the configuration and will block open networks as "not supported" while others you can get lucky and specify an open network and leave the password field blank. We've ...

Good Evening, Anyone else having fun with these Amazon Deepracers and like to share their experience with them and any fun quirks. First item I listed just an example experience from a past IoT device – the second one is what the end-user is getting after we got it connected to our network. But figured ...

RE: 8.10.0.7 and Airgroup AirPrint Problems

Posted By Christopher Johnson 07-17-2023 11:55:32 AM
Found In Egroup: Wireless Local Area Networking \ view thread
Registration issue I think was the "Personal Device Registration' – we went from 8.7 to 8.10.0.5 – and discovered AirGroup wasn't respecting the "Personal Device Registration/Owner Attribute" – so anyone on that AP/neighbor – could discover the device. AirGroup Engineers were good to work with and got ...

RE: Windows 11 laptop automatic switchover from LAN (dock) to wifi not happening

Could this possibly be related to Windows Defender Credential Guard? Microsoft is making Credential Guard enabled by default in latest builds of 10/11 - which breaks SSO - MSCHAPv2 - and solution is to switch to EAP-TLS. I'm curious if this is the behavior that you're seeing. Known Issue with Windows ...

Wonder if it's true 802.11g – or 802.11g but ONLY if 802.11b data rates are enabled like good ole Nintendo Wii, older X-Box, and an older gen temperature sensor. �� But yeah, good ol marketing! -Chris

We're not a Cisco Wireless Environment, but how does your controller CPUs look during those periods of time? A few of our datapath CPUs on Aruba Controllers were maxing out, and traced it back to our favorite pal "multicast" that was making itself to the wireless network. Symptoms was 3 of the datapath ...

Thanks for everyone's feedback over the past few months. We upgraded to 8.10.0.5: So far haven't seen the one-way audio issue that Trent mentioned – hopefully that's a good sign they fixed that particular problem. The more concerning part – wanted to know if anyone else is running into this problem. ...

Recently discovered this while reviewing Clearpass 6.11 documentation.
