I am not exactly sure what the microwave test is... but I have the router in my kitchen and very near my microwave (5ft away). For about 4 months the router has performed fine. It has never turned itself off or reset.
No, but I have had the router for months now and I have not had to reset it once. No issues at this point. My only concern is that it does run pretty hot sometimes. This may be normal, but I worry this may shorten the life of the unit.
I ran the microwave for about 5 minutes boiling some water and performing the speed test during the run. No noticeable difference between the microwave running or not running. About 20mbps download and 3mbps upload either way. I am not sure how much frequency or leakage varies between microwaves, but I have no problems at all with the router.... and the ping time was about 40ms either way.
