How to access older revisions of Router OS to do a downgrade

In a previous post I asked how to do a downgrade. The answer was Netinstall and so I am on the right track but here is a really dumb question…

Where do I get/download older revisions?

I want to revert from 6.15 on my RB2011 units to 6.07 because they are crashing with kernel panics.

I think it might be the new pppoe as suggested by a helpful guru yesterday.

Help would be very much appreciated.

Try to netinstall 6.15 first and see if it will be crashing further.

Thanks.

So a re-install of 6.15 thru Netinstall instead of thru the Winbox Upate (which is how I hosed the older router) ?

And for the new RB2011 that just arrived and already has 6.15 on it and also crashes ?

Even in this case. You will not damage anything and it may start work. It would be the same at worst.

Got Netinstall running and reset the RB2011 and booted from ethernet and loaded 6.15.

Router still crashes and i didn’t even run pppoe. I ran dhcp client on ethernet port 1 to a different ISP.

Is anyone running 6.15 on an RB2011 with success? I am beginning to wonder !

Me personally for instance. Without any problems.
