If it works, great. If not, you may have destroyed your router and wasted hours of downtime.
Since my background is in human factors and user experience, I look at it this way:
- For a feature X (here it's saving/restoring your settings), how much benefit is it to the user? If there is an error (either user or computer) during task flow, how much does it impact the experience?
Given that the config save/restore "feature" does not work reliably and can cause disastrous consequences, I would think that D-Link would remove the instructions to actually USE the feature when upgrading to 1.31NA. I may have to work through an RMA to deal with my issue (see this thread: http://bit.ly/N1P0X).
For us tech-heads, writing down our settings or creating screen-captures is second nature. But think of all the non-tech users who are simply following D-Link's recommended upgrade procedure and potentially damaging their routers. Where did the QA and User Experience departments go?
Sigh.
