There are currently five (5) wireless standards, each with its own features.
|Standard||Band||Maximum data rate||Channel width|
|802.11b||2.4 GHz||Up to 11 Mbps||20 MHz|
|802.11a||5 GHz||Up to 54 Mbps||20 MHz|
|802.11g||2.4 GHz||Up to 54 Mbps||20 MHz|
|802.11n||2.4 GHz||Up to 450 Mbps||20 MHz|
|5 GHz||40 MHz|
|802.11ac||5 GHz||Up to 1300Mbps||20/40/80 MHz|
For example: Let's say you have an 802.11ac router, and the wireless adapter in your laptop is an 802.11g adapter. Your adapter has a limitation of capping out at 54Mbps per 802.11g standard, while an 802.11ac router can reach data rates of up to 1300Mbps. When your computer transfers data more slowly than your high-tech router, upgrading your wireless adapter to a newer wireless standard can help speed up your connection.
This article will help you check the wireless standard of the adapter installed on your computer, so you can decide if you need to update your wireless adapter.
Below are two (2) ways to determine the type of wireless standards your wireless adapter supports:
