Re: [WIRELESS-LAN] Nyansa
I’d be willing to provide our experience if requested. We’ve had Voyance in production since around September. Overall the product democratizes wireless troubleshooting from my engineers to the service desk or departmental distributed IT, making them more capable of resolving issues on a first pass instead of constantly escalating client-related problems. The direct cost savings in allowing the service desk to resolve the most reported incidents instead of requiring my team to resolve them made up approximately 15% of the total cost of the product at our tier at 100 cases per year for each type of case, but that didn’t factor in that we’d also be saving time (and cost) in getting our other committed projects out of the door quicker leaving more time for professional development. At our current tier, the product is worth what was paid. Being able to show our CIO team/leadership team that the changes that we’ve made are beneficial and seeing where we stand against other similarly sized institutions has provided some direction on where we want to make future improvements. Being able to decrease mean time to resolution and increase first pass resolution times for more complicated client-issues has had a positive effect on the trust relationship between our faculty/students and central IT, but we’ve also invested significantly in our infrastructure within the last year so it’s murky on how much reduction in resolution times has benefited us versus our infrastructure investment. We use Prime Infrastructure for wireless management/configuration, AP placement mapping and MDF/IDF identification. Our reliance on Splunk for log correlation with reported issues has dropped significantly. If you have anything specific you’d like to know, please feel free to reach out to me off list. -- Devyn Moore Network Enterprise Systems Team Leader Campus Wireless Network Engineer Information Technology Services http://directory.uark.edu/people/devyn From: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> on behalf of Hector J Rios <hr...@lsu.edu> Reply-To: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Date: Monday, February 13, 2017 at 8:46 AM To: "WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU" <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: Re: [WIRELESS-LAN] Nyansa Me too!

Re: [WIRELESS-LAN] Question about Cisco 1810w APs in residential buildings
Ian, I appreciate your response. I’ll start looking at 8.2.121.11 to see if it makes sense for our environment. I’ll take the information you’ve provided and include it into my PoC justification summary. If absolutely required, I will separate these devices onto our unused secondary hot/standby cluster, but my preference is a single (stable) code version throughout our environment. We may recommend that they purchase a third hot/standby cluster for their environment since their license counts are going to triple in most buildings. Since they do not manage any of their infrastructure, they’re not aware of these types of issues and just expect things to work and be cost effective. Again, thank you for the useful information.

We bought the first batch of 1810’s off the assembly line and they did not have a means to talk to the controller (DNS would not work nor DNS options). We had to manually point them at our controller. However, *if* you bought a recent batch (after Sept) I have been told they have reimaged all the AP’s at the assembly line and that issue has been resolved. Other issues we have seen (and in 8.2.130.0 most have been resolved) are AP’s rebooting frequently. More recent code upgrades have fixed that issue, however we are still having an issue with the 1810’s and the wired ports. As to redundant WLC’s I would go to 8.2.121.11 at a minimum, there is a WLC issue with SSO as well as the 1810 issue that I found (the hard way) to be the minimum version to start at. Things are improving. However, 500 1810’s deployed = challenging times. The good news is, is that the students memories are short and I expect once these issues get ironed out, smooth sailing.

Re: [WIRELESS-LAN] request for info on WiFi Analyzer Pro software
We use the Ekahau Site Survey Professional package which comes with a spectrum analyzer (Metageek Chanalyzer). The site survey planning, troubleshooting and reporting features are incredible (especially if you use Cisco and have WCS/Prime Infrastructure). We have used the Yellowjacket Wi-Fi analyzer in the past and the Ekahau/Chanalyzer package blows it out of the water in terms of ease of use, battery consumption and mobility. The professional package also comes with Ekahau's mobile site survey software for Android that will passively check for wireless network issues and report them as you're walking around campus. Overall incredibly happy with the software and support. -- Devyn Moore Campus Wireless Network Engineer Information Technology Services http://directory.uark.edu/people/devyn From: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU>> on behalf of Steve Fletty <fle...@umn.edu<mailto:fle...@umn.edu>> Reply-To: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU>> Date: Friday, December 11, 2015 at 3:03 PM To: The EDUCAUSE Wireless Issues Constituent Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU>> Subject: Re: [WIRELESS-LAN] request for info on WiFi Analyzer Pro software We use it and it works well. They also have a less expensive tool, which includes site survey capabilities, called Aircheck (same name as the stand-alone hand-held unit), for both Windows or Android. Not as full featured, but may meet basic requirements...I haven't used that for a survey yet, but it would be a decent tool for techs or students without extensive WiFi skills. You might want to check out Ehahau too, especially if you want to do any planning. The Ekahau survey tool has a planning tool that lets you use CAD files, if you have them, and assign RF properties to obstacles on import, which you can't do in the Airmagnet planning tool. They require you to draw obstacleswhich is just too painful.
