Wireless-N is the only protocol that can work in both bands 2.4GHz and 5GHz.Ĩ02.11ac USB adapters with drivers written for the Linux have been slow to come about. This gives it a huge advantage over Wireless-N the last WiFi protocol introduced, which can move data up-to 150/300 Mbps.Ĩ02.11ac only works in the 5 GHz band which means range would be sacrificed for faster speeds. The new 802.11ac protocol introduced in late 2013 is the fastest WiFi protocol available.Ĩ02.11ac can move data up-to a theoretical 5Gbps with the most common speed 1.3 gigabits per second (Gbps) In a crowded wireless environment signals begin to collide which than needs them to be resent slowing down a network. Radio waves can travel better on lower frequencies than higher frequencies giving the lower 2.4 GHz better range than 5 GHz.ĥ GHz was opened up to WiFi in 2013 since the 2.4 GHz band has become overcrowded and full of signals. Wireless dongles that transmit in the older 2.4 GHz frequency can transmit a signal better than the new 5 GHz band. While not common some manufactures have been known to change a adapter chipset with new versions.Īs always be sure to read the reviews on Amazon or elsewhere to be sure an adapter is a good fit for you and your setup.Ī dongle with a large external antenna will have better range, the frequency can also matter. When looking for an adapter to work work Linux be sure to look at the chipset the adapter uses and if the manufacture has changed it.
