Hello,
I own 3 Cisco CBW familiy devices for some months now (240AC as primary mesh, 141ACM + 142ACM extenders), expecting those mesh capable devices to do more than my previous - non Cisco - setup.
Great management and very stable wifi, but... I also often have issue acessing some devices on my network. At apparently random (after 3-5 days usually, 2 times at least today), some (even wired) devices are not avalaible through the wifi setup.
This could be a lan device on the network or another wifi device (no peer 2 peer block option turned on). The most annoying issue is when the not avalable device is either the DNS / DHCP server or the Internet gateway.
When the issue fires up: ping from my wifi enabled notebook on a device (the wired LAN mail server for example) fails with timeouts. When I connect to another server and ping the mail server from there (yes: 2 physically distinct machines), it works. Only the wifi mesh is unable to see it at some point. Confirmed by the "ping test" from the primary AP tool (ping fails also there).
I reboot the AP and it will work again for some time.
My setup is pretty simple: Wifi mesh 2G + 5G on a single SSID, transparent bridging, no tags on the LAN, no firewall, single 192.168.x.y/24 network (all servers under the last byte IPv4), no IPV6 enabled setup.
Any idea tho fix these required reboot to have a working (wifi) LAN again? I already did a full reset of all wifi devices / zero day setup with no success.
Philippe
