How to Improve Your Wi-Fi Signal

Wi-fi tip - perpendicular placement for antennas

If you have a router with adjustable antennas, I have a tip that can help you improve your wi-fi signal. Actually, this tip is from Alf Watt. He created the popular iStumbler Wi-Fi utility and is a former Apple Wi-Fi engineer. According to Alf (reminds me of the old ALF TV show), it’s best to point one antenna straight up and have the other antenna parallel to the ground.

According to Alf, the perpendicular placement is best because radio reception is maximized when both client and access point have matched polarization (antennas pointing along the same plane). Some client devices have antennas in vertical orientation, some horizontal. For instance, the current line of MacBook have their antennas in the black plastic part of the hinge in a horizontal orientation. By pointing antennas vertically and horizontally, you’ll maximize radio reception no matter which way your device’s antenna is oriented.

I actually have three antennas on one of my routers. I wonder how I should point the third antenna. I’m guessing it should be pointed at a 45 degrees angle. Anyone know the answer?

Review: WatchBot – it’s a versatile Wi-Fi camera

WatchBot camera

For more than a week now, I’ve been playing with a Wi-Fi camera called the WatchBot. I received the device for review on my geek dad blog. Thanks to the many features of the camera, you can use the Watchbot for things like home security, checking in on your children, monitoring your baby, and communicating with your kids. The Watchbot includes a camera, DC power supply, wall mounting kit, alarm connection adaptor, network cable, set-up CD, and user guide. BTW, the power supply is designed for the UK, but a power adapter for the US was included with my unit. The Watchbot retails for $237.95.

Giveaway: TP-LINK TL-WR1043ND Ultimate Wireless N Gigabit Router

TP-LINK TL-WR1043ND Ultimate Wireless N Gigabit Router - front view

I was contacted recently about giving away a TP-LINK wireless N router. To be honest, until they contacted me, I had not heard of TP-LINK (Facebook | Twitter) before. That’s why they reached out to me — so I can help spread the word about their wireless networking devices. The company didn’t send me a review unit, but according to the reviews on Amazon, users love the TP-LINK TL-WR1043ND Ultimate Wireless N Gigabit Router (List Price: $80, Amazon Price: $65) I’m giving away. I’m actually a little envious because I’m using an older wireless G router with only Fast Ethernet, which is significantly slower than the TP-LINK wireless router. In addition to the router’s speed, I like the USB 2.0 port (my router doesn’t have one so I can’t easily share my external drive) and its Signal Sustain Technology (SST).
