Ubiquiti publishes detailed data sheets for all of their products, but it’s hard to find all the information you need in one place for comparison purposes. That’s the purpose of this article.

First Generation Access Points

It can be confusing to distinguish between the generations of UniFi access points; you have to look at the access point label, or access it via the UniFi software to see the version. The performance difference between generations are significant. The datasheet for first generation Ubiquiti UAP wireless access points is still available.

On October 15, 2017, security researcher Mathy Vanhoef announced the discovery of KrackAttacks, a serious flaw in the WPA2 encryption protocol that encrypts most WiFi connections. Using this method, an attacker can decrypt traffic from almost any wireless access point (WAP) and clients. Every WiFi access point will need to be upgraded with patch that prevents this attack. Ubiquiti has already released a patch for UniFi access points that addresses this vulnerability. However, the upgrade process may not be straightforward, depending on the age of your access points. The following process will ensure that you are running a safe version of the firmware (3.9.3.7537 or later). Note that any upgrade will result in downtime for each access point as it is upgraded, so you will want to perform a rolling upgrade if you have multiple devices that will be upgraded while people are using them.
