I did the latest firmware update a few days ago (to v. 1.05.12), but I think my N900 router was working better with the previous firmware. Could someone please provide a link to the previous firmware. I believe it was version 1.04.11. I found the source code on this site, but I couldn’t find the zip file that contains the compiled firmware bin file.
By the way, it would be a very good idea to keep previous firmware versions available.
