RE: Cisco 9166 clients not connecting at 5 GHz

I tried both options, but that was running under 17.9.3. I have not tried again yet but am planning to in the future, probably when we get to 17.9.5 or 17.12.3 since we are planning to move to that for 9166D support. Larry Allhands Wireless Network Architect The University of Texas at Austin ...

Good morning Eric, I have not seen that here and am running 17.9.4a as well for a few weeks now. I'm going to look around further to make sure. The only time I had a similar experience with that was when I attempted the WPA 2/3 transition mode with two WLAN profiles on the same SSID on my lab controller ...

I have found the Google Bard gives me less filtered answers than Chat GPT. I have not tried jokes though.

RE: Thresholds for Wireless Service Quality

Yeah I actually design capacity based on the peak aggregate throughput in Mbps for a LCD (Least Capable Device) and an identified MDA (Most Demanding Application), especially for classroom. And in those cases I also design for clients per radio, not per AP, as many APs now have multiple radios plus dual ...

We will keep our eyes open, but we are currently running 17.9.3 campus wide with 11K APs (2700, 2800, 1562, 9105, 9120, 9124, & 9166s). I have not seen any tickets like this yet, but we just upgraded last week and students are away. ------------------------------ Larry Allhands Wireless Network Architect ...

RE: Newer WAPs and high-density design

I no longer design for clients per AP, but rather active client applications per radio, especially considering the XOR capabilities. I prefer per client aggregate throughput as a capacity planning metric rather than number of associated and connected devices. The thinking behind this is that using modern ...

Is anyone supporting wireless fire extinguisher monitoring systems on their campus WiFi

If so, which are you supporting and what is your experience with it? Any limitations on WiFi technologies? Any specific considerations we should look out for?

Just remember when mixing that looking forward there will be a different EOL & support dates for 9120/9130 vs 9136/9166. I inherited a mixed Cisco environment and we are dealing now with having to run disparate controllers & software versions in many buildings while we are upgrading our environment and ...

We are beginning to look at these Cisco alternative offerings as well. Did you find any good information you can share? We are currently Cisco WLC9800s. I have visited the University of Michigan (Aruba 6E on-prem deployment) and am going to UT Arlington to see the Juniper Mist deployment next week. ...

Thanks Dan, Although 60GHz is something I have not yet deployed, I have had a lot of experience with Ubiquiti PtP and PmP radios in the past and have never had a bad experience, so this is in line with my thinking as well. Cheers, Larry Allhands Wireless Network Architect The University ...

Does anyone have any experience running Cisco' s FT Mixed Mode on 9800 WLCs in a large environment. I know when it first came out it was not recommended due to so many devices having trouble. Have they fixed it and does anyone run it? We are considering this in an attempt to reduce our processor load ...
