A small and compact wireless USB dongle may seem like it'll save you a lot of space, but unless you absolutely need something that is small, then bigger is still better. A bigger wireless dongle means that it has a bigger antenna - or even two antennas in the case of the one I have here today. The TP-LINK TL-WN822N is a high gain wireless N USB adapter with two external 3dBI antennas. This adapter may not be as small as a quarter, but it's still not much larger than a pack of gum which makes it easy to pack away and travel with too. Let's see how the TL-WN822N stacks for it's great price.
