Still used, but moved house semi recently and my new place is long and thin, and wireless doesn't reach to the absolute ends.

Moving to Unifi AP's and Router.

Rock solid on both Fibre and ADSL. WiFi is fast and stable, and it has good range.

Used with an external HDD plugged in for backups, has worked well.
