Hi chaps,I'm trying to recover a C9130 which failed to upgrade the code and now is in a loop boot, but it seems to me that the recovery process from U-Boot couldn't be the same as C9120 from this guide as C9130 is unable to ping gateway, any ideas?Re...

Hi community,I've been receiving many complaints from users that were unable to connect to the corporate WLAN with PEAP-TLS (but also on BYOD SSID with PEAP).After investigating I found all those sites where with AP3702. Digging into debugs, I've che...

Constant utilization use to lead to a non Wi-Fi interference (unless been impactede by a code defect or radio malfunction). Could you manually assign channel 140 (or channel 48) to this AP and see the value it reports?

The quick way to check if AP mode is Flexconnect or not is to use this command on the CLI, if it returns "FlexConnect" then you are there:grep include "AP Mode " "show ap config general <your_ap_name_here>"Regarding issues when moving from legacy Air...

If apple devices do see very poor signal strength (compared with other devices such as Androids or Windows) then this seem to be a defect with the driver/firmware that maybe fixed with a code upgrade.

High utilization on the channel could be due to high load in connected clients such as sharing or downloading content. But if this is constant all the time, and the devices are also disconnecting, this could be due to a non Wi-Fi interference source....
