Gary, I'm with Paul...if you've got iffy wifi, a NUC isn't going to solve the problem... I experience wifi issues with my NUC and I know the signal is good. As a workaround, I find plugging the ethernet cable of the NUC into a mini-switch stabilises the wifi...maybe it's a Windows issue
I do think they're great little machines though...the 8th Gen are the best so far, and i5 is worth the extra few pennies over the i3 as it's quad-core over dual-core (although the individual core performance is comparable).
