I'm not super familiar with SF construction materials but I wonder if that plays a part in it too? If your neighbors are separated by concrete walls then you're probably getting less interference from them than you'd think and your mesh might actually work better(?)... but what do I know since I'm no networking engineer.

It's all wood construction, originally stick victorians with 2x4 exterior walls. My "loudest" neighbor is being picked up on 80MHz at -47 dBm.

Old Victorians in SF will sometimes have lathe and plaster walls (the 'wet wall' that drywall replaced). Lathe and plaster walls often have chicken wire in them that degrade wifi more than regular drywall will.

Man, at times in my life I would've killed to get a -47 dBm or better signal.
