During the weekend I upgraded the firmware in my dsl router. I then started experiencing timeouts, so I tried to downgrade - no can do. The geniuses at AVM didn’t consider that an option. “You have newer firmware - go away”.

So I called the dsl provider. It turned out that coincidentally just after I upgraded, the network went down. The router firmware was not the cause of the problem, then. And afterwards router was working fine.

But the problem remains. I don’t really care whether there is an extra-seekrit way to downgrade. After all the years of doing bios upgrades on my home pc, and flashing the graphics card, I treat being able to undo that kind of process as a given. If it is not possible, I want to know it upfront. Jeez, they didn’t even bother to put it on their website!

IMHO, any decent upgradable thingy should be also downgradable. If it’s not, it’s wrong. If it’s not and there is no indication that it’s not, it’s plain dumb.

But hey, I can understand you, guys - a brain is not downgradable, when there’s nothing to downgrade to.
