If a gadget uses the older 802.11g or b standard, there isn't much you can do to speed it up. If your computer is using 802.11g, consider upgrading to 802.11n using an external USB wireless adapter.

Of course, your router needs to support 802.11n as well to see any benefit. If your router is an old 802.11g (or a really old 802.11b) model, it's time to upgrade. Click here for a comprehensive router buying guide that will help you pick the right one. 

One of the many perks of a new router is they can simultaneously operate on two separate bands - the older 2.4GHz band as well as the faster 5GHz band.

The 5GHz band is less prone to interference from other Wi-Fi networks and Bluetooth signals, which makes it more suitable for streaming and gaming. Some of your newer gadgets can probably operate on this band.

If your router already supports 802.11n, you might want to make sure your router's firmware is up to date. Instructions for checking the firmware will be in your router manual.

Firmware is like your router's operating system. Most updates fix minor bugs, but sometimes a major update significantly boosts performance or offers features that didn't exist when the router was first sold.
