I use several of these. They are all working fine for me over 150' from the nearest AP. I use my microwave with no issues. I believe that problems may occur if you live in a highly populated area where others are using many wifi devices. I set static IP addresses and have zero issues with connectivity or drop-outs.
I'll try find time to post some still images after the holiday from the DS-CD2032F-IW and a couple other 12mm lens cameras to compare the field of view width and night sensitivity. I have fields that are 1000-2000 feet and will put out some targets to test. I do know that at night, perpendicular car headlights will trigger alerts from Blue Iris over a mile away from the 2032.
