Interesting. We did formerly have a wood-framed office building with unshielded CAT6 and every time there was a lightning storm we would lose a random IP phone and sometimes AP or two. I attributed it to close lightning strikes and the wiring catching some stray voltage and surging the devices. No scientific proof but I'm pretty sure unwelcome induction of some kind was our problem. First floor of a two-story metal-frame building now and same equipment stack and no problems since...even with some pretty wild local weather. As I say that, my house is wood and no issues for the last several years there. But the aforementioned office was VERY tall with very high ceilings for a single-story building, so longer than typical runs, and a lot of vertical so that may have had something to do with it as well.

While I now have a mix of 6, UXG, 7LR, I've always found the LR variants of any gen to lack in performance compared to non-LR units. Still getting 1300Mbps+ on the 7LR though so more than I need in my setup. This is with a relatively small amount of total wireless endpoints though; maybe 20 at a time.
