This is what I have: Firmware Version: 1.11NA Hardware Version: A1. I checked the box and that version you mention is what came with it. I should of never upgraded firmware. You seem to know what you are talking about. If I were to exchange this one for a different DIR-825 and have saved my configuration, would I just be able to upload my saved configuration to the new router? Or is it router serial number specific? Also why is it that even with my other router, when I am downloading alot of stuff, after a while it seems to drop the connection. It is just overworked?
I wouldn't use the same configuration if you got a new 825 running 1.01. It might accept the file, but since they run different versions, it might not work correctly. Especially since you are going from 1.11 to 1.01 (backwards).
There have been issues with the latest firmware's on both these models. For me with the 655 running 1.31, I have encountered port forwarding issue and issues with the router slowing down and basically freezing. The 825 running 1.01 has been great, no issues that I have noticed with lots of torrents and constant web use by around 5-6 people.
One thing I would do on the 825, is turn of DNS relay, even if you end up getting one that's running 1.01.
Anyway, my 655 on 1.11 ran months without being restarted, and 825 running 1.01 has been just as solid. I never should have upgraded my 655 to 1.31.
