Problems with new firmware 2.8.0.1

Hi, I deployed the new firmware 2.8.0.1. Seems to be more stable when the link is established, but I have some concerns.

Last week were various blackouts over one of our backbones. The links took long time to reconnect after the power returned and one of them need varios reboots to reestablish the link. The previous firmware(2.5.2) didn’t has this problem. Other problem is that when the AP or client has not established the link the web interface is very unresponsive. Any ideas? Has someone more reported this problem? Thanks in advance.

You are the first, how long would the device normally take to reconnect after a reboot?

3 to 5 minutes. Or on extreme cases never reconnects. Only after 2 or 3 reboots on the client side.

Can you pull the support files before reboot? You will probably need to contact Mimosa Support on this one, you being the first to report problems around here I don’t know any tips or tricks yet.

This is the log of the AP after upgrade. This time the client not reconnect.

How can I upload the support log?

Another question, Is safe to downgrade to the previous version?

Hello én elvagyok tiltva a chat nem tudok írni hetek óta pedig van baj a c5c 2.8.0.1 formwarevel… 100 megabit max test ok de internet sávszél nem jó valami nem ok korában a 2.5.2 vél nem volt gond

Update on the issue. This seems to be related to the auto power option. When enabled the association took time or never reassociate. When disabled in the same radio the association took less time and always reconnect. Can this help to find the bug.

I upgraded a C5X with the 2.8.0.1 and it choked when I tried to log back in. I stopped upgrading other radios. Don’t think 2.8.0.1 is ready for prime time.

Update 2 on the issue. I have changed the radios to fixed power and they don’t appear to take the change. I put it to 21dBm Tx conducted and it appears to be transmitting 20 then 21 then 22 and go back to 20. Tx power is ever in auto mode.
