Similar experience with Apple access points. After getting fed up with crappy gear which needed a daily restart, had awful range, overheated despite proper ventilation, would in theory allow simultaneous dual band but in practice really didn't, etc etc etc I bought a Time Capsule (the Airport Extreme with built-in hard disk) around 5 years ago and couldn't be happier. The connection has always been absolutely rock solid. My only complaint is that the client app got dumbed down more and more, down to a level I found really irritating.

It's a real shame they decided to discontinue them - they were absolutely the single consumer brand which didn't plain suck in my experience. Awful experience with Asus (overheating), Netgear (5 disconnects per hour), Cisco/Linksys (radio part died after a firmware upgrade, long fight to RMA a 3 days old unit), D-link (signal wouldn't cross a single wall), etc.

Fortunately I recently decided to look past the consumer products and discovered Ubiquiti. What a breath of fresh air. Amazing performance and range, all the stability of Apple without the Fisher-Price interface.
