While Wi-Fi is convenient and all, it doesn’t solve all your networking/streaming problems especially if your house has dead spots. Zinnet takes care of those situations with the LinkE. The network adapter uses your existing powerlines for data transmission. Get up to 200MBps throughput speed from the relatively small package that’s also low in power consumption. A 128-bit AES encryption makes sure your data stays private across your electrical/digital network. $100.

Wireless networks are cool and convenient but it’s not without its drawbacks. Those freeloading neighbors or nasty hackers are just a few keystrokes away from your precious files, so if you’re looking for an alternative to wireless home networking, this product may be for you. The Belkin Gigabit Powerline securely networks your house via the existing power lines. Data transfer speeds of up to 1000Mpbs are supposedly achievable but actual numbers may vary according to existing conditions. The plug-and-play capability makes sure that even the networking noobs will be able to set this system up with minimal effort. $150.
