If you have a large house, or deadspots, or a pool / outside area, etc. and struggle to get coverage, I'd suggest the ubiquiti unifi series of stuff. I've heard the Cisco Meraki stuff is good as well. Things have changed a bit, and you are no longer forced into consumer gear vs corporate gear. I've found the unifi stuff to be somewhere in the middle. For a little more cost and elbow grease to set up, you get some nice features like: real access points with seamless auto switching as you roam around, real vlans and guest networks, and good quality of service options (like limiting users bandwidth). In layman's terms, you can put access points around your house, even outside, you can roam around and your phone/laptop autoswitches from AP to AP, you can set up fancy guest networks with limited access, and you can do things like limit your kid's bandwidth so they can't kill your internet connection as they stream 12 things at a time. Another nice feature is you can connect an AP to another AP in a wireless extender style fashion that actually works.
Worth checking out if you're willing to spend a bit more and have some technical ability. All a moot point if you're living in a smaller house with no kids... Depends on your needs.
