Turn Your Windows 7 PC Into a Wireless Hotspot

Everybody's got a wireless network at home, but if you've ever wanted to get your iPod touch, iPhone, or other wireless device connected, but all you've got is a wired network at work, school, or elsewhere, Windows 7 makes this process trivial.

Not using Windows 7 yet? You can accomplish the same thing in Windows Vista, XP, and even OS X—the Windows Vista method is almost identical to Windows 7, but XP requires a few more steps.

Before we begin, you should make sure that you've got a laptop or desktop with a wireless card that isn't currently connected—if your laptop is connected to the wired network, your wireless card should be free, and we can use it to allow access to the internet. Note that you have to be plugged into a wired connection in order to share the connection wirelessly with others, or have a second wireless card. Readers should also note that this won't work on (some) work networks that use group policies to enforce TPS report cover sheet boredom and prevent you from having any fun at all.

Full size

You'll want to start out by heading into the Network and Sharing Center through the Control Panel, or you can quickly get to it by right-clicking on the network icon in the system tray. Once you are there, find the link for "Set up a new connection or network".
You'll be prompted with a wizard that allows you to connect to VPNs, dial-up, or create a new ad hoc wireless network, which is what we want to do. You can easily use an ad hoc network to share files back and forth between two computers, but today we'll be using it for sharing the internet connection.

Full size

You'll need to give your network a name and choose some security options—remember that WEP is extremely easy to crack—and you'll want to make sure to use at least a decent sized key even for WPA2. The really important option on this page is to remember to check the box for "Save this network".

Full size

At this point your ad hoc network should be running and ready to start connecting your devices, but you'll want to hold off just a minute.

Full size

You'll notice that the ad hoc networks that you create get added to the quick-select wireless network list—when you disconnect from your ad hoc network, it's the same as stopping it. Connecting to the network is the same as starting it back up; this way you can quickly switch back and forth between connections with just a few clicks.

Full size

The last step is enabling connection sharing through your regular network card, which will allow anybody connected to your ad hoc wireless to use your internet connection. To do so, you'll want to head into the Network and Sharing Center, click the "Change adapter settings" link on the left, and then find your network connection in the list—it's very important that you only enable internet connection sharing on the adapter that is actually connected to the internet. In this case, my internet access at work goes through my Local Area Connection, so I've enabled it there.

At this point, you should be able to connect any wireless device to your new ad hoc network and access the internet, or even share files directly with your laptop.

What Are Magnet Links

Soon, popular torrent site The Pirate Bay will no longer host torrent files. Instead, it will only offer magnet links. Magnet what now? You may have seen the term "magnet link" before, but if you haven't used one, here's the lowdown on what this change means for you as a BitTorrent user.

How Magnet Links Are Different From .Torrent Files

When you download a .torrent file, you're essentially downloading a small file that contains information on the larger files you want to download. The torrent file tells your torrent client the names of the files being shared, a URL for the tracker, and more. Your torrent client then calculates a hash code, which is a unique code that only that torrent has—kind of like an ISBN or catalog number. From there, it can use that code to find others uploading those files, so you can download from them.
A magnet link does away with the middleman. A magnet link is essentially a hyperlink containing the hash code for that torrent, which your torrent client can immediately use to start finding people sharing those files. Magnet links don't require a tracker (since it uses DHT, which you can read more about here), nor does it require you to download a separate file before starting the download, which is convenient.

How to Use Magnet Links

Magnet links are dead simple to use. If you head to the Pirate Bay now, you'll notice that magnet links are now the default, with the "Get Torrent File" link in parentheses next to it (a link which will disappear in a month or so). Just click on the magnet link, and your browser should automatically open up your default BitTorrent client and start downloading. It's that easy.

What This Ultimately Means for You

The short answer is nothing. In fact, it could mean that downloading torrents takes one or two fewer clicks, since all you have to do is click on the link to start the download. When magnet links first came out, not all torrent clients supported them, but now you can use magnet links with just about any semi-popular torrent client out there—including our favorites uTorrent, Transmission, and Deluge, among others, so you shouldn't notice a problem with that.
The main reason torrent sites are moving toward magnet links—apart from convenience to the user—is that these links (probably) free torrent sites like The Pirate Bay from legal trouble. Since The Pirate Bay won't be hosting files that link to copyrighted content—that is, the torrent files—it's more difficult to claim the site is directly enabling the downloading of copyrighted material. Whether this semantic leap actually protects torrent sites remains to be seen, but for now, you can sleep soundly knowing that the sites will stick around for awhile longer and that your torrents will take one less click to get started. Of course, if you're using a public site like The Pirate Bay, we highly recommend you set up a proxy and encryption service like BTGuard to protect your downloading from prying eyes.
