TL;DR: Ubiquity UniFi gear is awesome!
When I moved into my current house one of the bigger technical challenges has been to get WiFi that works throughout my house reliably. Since we can only get regular phone lines here I’m on a VDSL2 internet connection which runs at 80/20mbit. The problem is this comes in via my office which is in the corner of the house. My kids bedrooms are in the opposite corner of the house so getting WiFi to reach that far becomes a technical challenge.
