Problem with WNDAP360 after updating WC7520
Yesterday I updated our WC7520 controller to the latest firmware (2.5.0.39), and since then all our APs (WNDAP360) are rebooting and loosing connection. They can work for a few minutes, then they fai...
Hi Johanhelin,
Thank you for the quick reply.
The problem is definitely because you have unchecked 802.11na, this is the bug we have in 2.5.0.39 firmware, and we have fixed it in 2.5.0.40 and later versions. We are in the process of web releasing the firmware 2.5.0.42 with the fix. Until then eventhough you are not using 802.11na Radio as a quick fix to this issue can you check "Turn radio on"?
thanks,

The radio schedule on/off is set to off. The SSIDs are either Open, WPA2-PSK with TKIP + AES or just AES. No mixed mode configured what I can see. The automatic channel allocation is configured, can this be a problem?
Hi Johenhelin,
Thanks for quick reply. Can you give us the information on the following
1. Can you see in Configuration->Wireless->Wireless page "Turn Radio On" is checked or unchecked in the basic and advanced groups.
2. Does all the APs are in basic group or spread across multiple groups.
3. What was the firmware version from which you have upgraded the wc7520 to 2.5.0.39. Are the APs started rebooting only after upgrading to this firmware?, and there were no AP reboots in the previous firmware?
4. Are all the APs going for a reboot periodically for every 5-10 minutes?.
5. Can you go to Maintenance->Logs & Alerts -> Save Logs -> AP logs page and save the AP logs for the ones which are rebooting, and upload here?.
6. Does firmware rollback to the previous release resolve the issue?.
thanks,
laxman.
1. In basic there is 802.11b/bg/ng where the "Turn radio on" is checked. There is also 802.11na where the option is unchecked. In the Advanced option there is a group called "Group-1", 802.11b/bg/ng and 802.11a/na are both checked but greyed out.
2. All the APs are in the basic group, none are in the advanced group called "Group-1".
3. I think it was version 2.5.0.31 but I might be mistaken. No, there were no AP reboots in the previous firmware.
4. Yes, this is exactly the behaviour they are having. They work for a few minutes, then reboot.
5. All of them (25) are doing it, so I'll give you a log from one of them. How do you upload files here?
6. I haven't tried this yet, hoping for another solution first.

Yes, this solved the problem for now. Is there any way to get a notification when the new firmware is available?
