There are a few things to consider when buying a good WiFi adapter. The first is the type of connection you need. If you just need an adapter for your home or office, a wireless-N adapter may be all you need. However, if you plan on using your adapter at a public hotspot, you'll want to get an adapter with a stronger signal.

The next thing to consider is the speed of the adapter. Some adapters are faster than others, and will allow you to download files more quickly. If you're travelling and need to use public WiFi hotspots, it's important to find an adapter that can keep up with your needs.

Finally, make sure the adapter has a good warranty. If something goes wrong with the adapter, having a warranty will help ensure that you're covered.

3. Size: Make sure the adapter is small enough to fit in your laptop or desktop's USB port.
