Clients disconnecting

I have two Omnitiks, they were both using the version 6.4.
Then I noticied that all clientes of the first omnitik were disconnecting constantly, so I’ve made a update to v6.31 and all went fine… no clients disconnecting on that omnitik from now on.

I just noticed that the same problem were repeating in the second, today. I’ve made the upgrade to v6.33 (the current one) but the problem persists. And I can’t download the all_packages files from the v6.31 to make the downgrade on the second omnitik.

Where can I find it? I have:
http://download2.mikrotik.com/routeros/6.30/all_packages-mipsbe-6.30.zip
http://download2.mikrotik.com/routeros/6.32/all_packages-mipsbe-6.32.zip

but no http://download2.mikrotik.com/routeros/6.31/all_packages-mipsbe-6.31.zip

It could be an interference problem.

I’d try 6.30.4 (latest bugfix) making sure Omnitiks have latest firmware installed also.

From that onwards you can start trying other channels, looking for interference, etc.

That version solved my problem. Thank you so much.
