<p>Wifi is tricky to get right and its only noticed when it isn't working. With a few simple tweaks wifi performance can be greatly improved.</p>
<ul>
<li>Generally, you don't want an access point to have to reach more than one room over. ~30ft</li>
<li>This goes hand in hand with too few access points. If the transmit power is too high the signal from an access point can overpower one that may be closer to the device trying to connect.</li>
<li>In especially dense urban areas there are lots of wifi networks. They all use the same few channels to communicate so selecting one that is not as highly used will allow for easier communication.</li>
<li>Lots of devices can give off 2.4GHz signals. Or in short, don't put your access point on top of the break room microwave.</li>
</ul>
<ul>
<li>Ubiquiti: Sleek, does the job well, user friendly, cost premium, no recurring charges</li>
<li>TP-Link Omada: Does everything Ubiquiti can just cheaper. Not as user friendly</li>
<li>The Aruba IAP line is good for 2 or 3 ap deployments where a central controller would be overkill. Going beyond the IAP line is pricy.</li>
<li>Cloud managed. Industry leader. The price will reflect that.</li>
