Will, Sounds a little like this bug- CSCvn80477, only the bug mentions an older 8.5 release and on APs in static mode. I am currently running an escalation build of 8.5 (8.5.160.4) and have not yet seen this behavior. On Tue, Mar 3, 2020, 11:45 Will Dawes wrote: > If this is a known reported

David, We recently upgraded/redesigned the wireless network in several of our apartment style buildings and have found in our case that it was easier to mount the AP to the side of the existing faceplate and run a short cable from the data jack to the AP. Currently we are using the Cisco AP1810W.

Sam, Out of the roughly 400 2802 we have, 2 have failed due to experiencing boot room image checksum failures. The symptoms show up after a power cycle, AP draws power but status led stays off. If you console the AP you get nothing. Cisco has bug id CSCvf47017 in reference to this problem. On

Thanks everyone for the ideas. For those running Cisco AP1810W or AP1815W does anyone use the plastic spacer kits that Cisco sells as an accessory? If so, can anyone comment on the depth of one of these? I am curious to know if you could possibly modify the spacer by drilling a hole on one of the

Britton, We have been running 8.3.133.0 on several pairs of 5520s and 8540s without an issue. Our AP mix is 2602/3602, 2702/3702, 2802, and 1810w. We haven't ran into any APs yet that have hit the flash bug. On Dec 19, 2017 3:43 PM, "Britton Anderson" wrote: Happy

I would recommend you look at metageek's product line for this. Depending on how in depth you want to go, you can either get inSSIDer pretty cheap or spend a about 1000 and get a Wi-Spy dbx and Chanalyzer 5 to actually look at RF utilization. On Fri, Apr 15, 2016 at 2:56 PM, Allen Matthews <
