* Change Wireless Channels – I noticed that a neighbor recently changed their wireless channel to the same one I was on, it’s a weak signal but can still cause interference.

I logged into my wireless router and changed the wireless channel to a more obscure and unique one.

Keep all of your gadgets cruising along with a top-notch Wi-Fi router.

Dual-band routers allow you to assign a band to specific applications and clients, thereby easing the load on both bands. These have three radios—one that operates at 2.4GHz and two that operate at 5GHz.

These models are a good fit for multi-device households that experience heavy network traffic via lots of video streaming, torrent downloading, file transfers, and online gaming.

The most widely used Wi-Fi protocol, 802.11n, allows for maximum data rates of up to 600Mbps and operates on both the 2.4 and 5GHz bands.

It utilizes Multiple Input Multiple Output (MIMO) technology, which uses several antennas to send and receive up to four spatial streams, resulting in enhanced performance.

That said, they are perfectly adequate for things like Web surfing and connecting to social media services like Facebook and Twitter.

If one or more of your devices will be streaming video from a service such as Netflix, or connecting to an online gaming service such as Xbox Live, consider a dual-band router.
