I was a Wisp user for some time so I know the brand and it was a solid device overall. I looked into the UniFi products and the AP plus a controller is almost 100 euros more expensive than the Linksys device. I will look in the future for Ubiquiti devices but I think I am going to use a standard WiFi device (after all it is a one story flat not too big) and perhaps in the future I will buy a barebones so I can run pfsense with the current wifi device as a dumb AP.
