What operating system to use for Access Point?

If you are building an open-source, wireless Access Point, LEDE/OpenWRT is the best operating system for this purpose, by far. 

When it comes to router operating systems, most of our customers go for one of the three big names: OPNSense, pfSense, or IPFire. Not many people consider the alternative: OpenWRT/LEDE.

It turns out that OpenWRT, initially released in 2004 (16 years ago!), is still under active development and outperforms in many aspects other well-known brands.

OpenWRT is the only system we tested that fully supports 802.11ac mode and is able to achieve over half-gigabit, real-life WiFi throughput in Access-point mode. You can read more about this in our wireless throughput test.

Below you can see an access point we built for one of the customers that have 2 WiFi cards (wle200nx and wle600vx) to operate on both 2.4Ghz (802.11n) and 5.0Ghz (802.11ac) frequencies simultaneously. 

(ignore the additional USB dongle. It was not used).
