My DIR-825 B1 is basically a brick now with the WAN connection issues, so I figured might as well update to this 2.02NA Firmware posted on the Softpedia website.
Firmware update went through with no problems. Will be testing for previous WAN issues, and keep the forum updated if they were fixed or not.
