How to Extend Your Wifi Range


If you use a wifi network at home, there are undoubtedly limits to where you can access the signal. You might get a strong connection at the kitchen table, but take your laptop to the living room and you lose the signal. If you're looking to boost your signal a few feet or get a strong connection all the way upstairs in the back bedroom, we've got a handful of simple tricks and more advanced techniques to get you on connected to your home wifi from anywhere in your house.
Move your router:
* It's so simple, but many people don't realize that where you put your router really does make a difference. Obviously a central location is best, but for many, you are tied to putting the router where the Internet connection comes into the house.
* Beyond simple proximity, consider the router's height. The higher your router is on a shelf or cabinet, the less physical interference it's likely to encounter.  Move the router to the best possible position to take advantage of doorways and open spaces instead of walls and corners. Wifi might move through the airwaves, but furniture, walls and appliances can weaken your signal substantially.
* Signal interference is one of the biggest culprits that might be at work if your wifi is weak. Walls and physical obstructions block your signal, but signals emitted by any electromagnetic household object do too. Scoot your router away from anything that might interfere: cordless phones, microwaves, wireless game controllers, other wifi-enabled devices (TVs, etc.), Bluetooth devices, and evenflourescent lights and elevators.
Technical tweaks:
Once you've got your router in an ideal spot, take a look at your equipment. These next steps can help you further improve your wifi signal.
* Did you know routers have channels? If you live in close proximity to someone else with a wifi network you may both be trying to use the same channel and degrading your signals.
To find out if you are "crossing the streams" use WiFi Stumbler or inSSIDer to find the best and least-trafficked channel for your router to broadcast on. Once you've found the optimal channel, followthese step-by-step instructions to get your router on the right track.
* Depending on the age of your router, it may be slower than newer models. Upgrade an older b or g router to an n router to extend your range for relatively reasonable cost. There are some new n routers for as little as $30.  An n router can handle local electrical and physical signal interference better than b and g and may get you quite a bit more range.
* Lesser-known fact: The "current standard" 802.11n routers can operate at either 2.4 GHz or 5 GHz bands, and 2.4 GHz is far better at travelling through walls. So if you already have a Wireless-n router and need it to extend farther, make sure it's set to use 2.4 GHz instead of 5 GHz.
* The internal antenna on your laptop itself can be a factor in how much range you get. Even if your laptop has built-in wifi, it could be well worth picking up an external USB adapter, like this $30 option from Netgear.
This could also help an older laptop without Wireless-N support take advantage of faster speeds and improved range from a new 802.11n router.
Invest in network extension options:
* Wifi repeaters amplify and extend your wireless signal. Put a repeater within range of your existing wifi router and it will relay that signal out to hard-to-reach locations around your home or office. They cost about $90 and while they can theoretically double your range, real life results tend to vary considerably. If you've had good or bad luck with a repeater, we welcome any advice or testimonials in the comments section below.
* Powerline networking uses the electrical wiring in your house to extend your Internet coverage. This is especially good if you want to get Internet access in a back room or you want to connect a gaming console that's on an old TV in the garage. Plug one powerline adapter into your router and the other into an electrical plug. Then in the far room where you want connectivity, plug the other powerline adapter into an electrical plug and voila - you've got Internet, you can even put a second wireless router on that connection.  Setting up an alternative powerline network using your home's own AC power adapters can circumvent many of the most common wireless connectivity problems, and you don't even need to give up wifi altogether. If you look into getting started with a powerline setup, be sure to stick with one manufacturer when buying your equipment to avoid any compatibility issues.

Teen detained at airport for her purse



It's not unusual for 17-year-old to find themselves in hot water with the fashion police. But on a flight from Virginia to Florida, Vanessa Gibbs found herself detained by the Transportation Security Administration (TSA) over the appearance of her purse.
And just to be clear, it wasn't the content inside the purse that the TSA objected to. No, agency officials took exception with the design of a gun on Gibbs' handbag.
"It's my style, it's camouflage, it has an old western gun on it," Gibbs told News4Jax.com. Gibbs didn't run into any trouble while traveling north from Jacksonville International Airport. But on her way back home, TSA officials at Norfolk International Airport pulled her aside.
"She was like, 'This is a federal offense because it's in the shape of a gun,'" Gibbs said. "I'm like, 'But it's a design on a purse. How is it a federal offense?'"
After TSA agents figured out the gun was a fake, Gibbs said, they told her to check the bag or turn it over. By the time security wrapped up the inspection, the pregnant teen missed her flight, and Southwest Airlines sent her to Orlando instead. The changed itinerary created no small amount of anxiety for Gibbs' mother, who was already waiting for her to arrive at the Jacksonville airport.
"Oh, it's terrifying. I was so upset," said Tami Gibbs, the teen's mom. "I was on the phone all the way to Orlando trying to figure out what was going on with her. It was terrifying."
Less terrifying is the actual design on the purse, which is only a few inches in size and hollow. "I carried this from Jacksonville to Norfolk, and I've carried it from Norfolk to Jacksonville," Vanessa said. "Never once has anyone said anything about it until now."
Nonetheless, the TSA says the design could be considered a "replica weapon," something that the agency has banned since 2002. Just imagine what would have happened if Gibbs had also been wearing stiletto heels.

Survey says the best place to live is...



VIENNA (Reuters) - Vienna's excellent infrastructure, safe streets and good public healthservice make it the nicest place to live in the world, consulting group Mercer said in a global survey which put Baghdadfirmly in last place.
German and Swiss cities also performed especially well in the quality of living rankings, with Zurich, Munich, Duesseldorf, Frankfurt, Geneva and Bern in the top 10.
The Austrian capital, with its ornate buildings, public parks and extensive bicycle network recently reduced the cost of its annual public transport ticket to 1 euro a day.

Serious crime is rare and the city of around 1.7 million inhabitants regularly tops global quality of life surveys.
But Mercer warned that top-ranking European cities could not take their position for granted in the survey, which assessed more than 200 cities.
"They are not immune to any decrease of living standards should this (economic) turmoil persist," Mercer's senior researcher Slagin Parakatil said on the company's website.
Mercer, which also ranked cities according to personal safety, gave Athens a poor score because of clashes between demonstrators and police and political instability.
"In 2011 Athens is ranked in Europe among the lowest in the personal safety ranking," Parakatil said.
Oslo also fell to 24th place in the separate safety survey because of Anders Breivik's mass killings in July. It would usually be in the top 15, Mercer said.
Baghdad's political turmoil, poor security enforcement and attacks on local people and foreigners made it the worst place to live in 2011, both in terms of life quality and safety, Mercer said.
Political and economic unrest in Africa and the Middle East also pushed down scores in those regions.
"Many countries such as Libya, Egypt, Tunisia and Yemen have seen their quality of living levels drop considerably," Parakatil said.
"Political and economic reconstruction in these countries, combined with funding to serve basic human needs, will undoubtedly boost the region."
He said that while the outlook is uncertain for most of the world because of economic and political turmoil, cities in Asia-Pacific look set to benefit thanks to political stability and solid growth.
Auckland, Sydney, Wellington, Melbourne and Perth made it into the top 20 for quality of life in 2011 while Singapore was the highest-ranking Asian city in 25th place.

iPhone 4 Explodes Midflight on Australian Airline


iPhone 4 Explodes Midflight on Australian Airline (ABC News)
Apple’s iPhones are always among the hottest gadgets of  any holiday shopping season, but for one passenger on anAustralian flight, the phone was too hot to handle — literally.
While on Australian flight Regional Express ZL319 Friday, a passenger’s iPhone 4 (not the iPhone 4S, which is Apple’s latest model) suddenly started “emitting a significant amount of dense smoke, accompanied by a red glow,” according to a Regional Express statement.
The plane, which was flying from Lismore to Sydney, was in the midst of landing when the incident occured. “In accordance with company standard safety procedures, the flight attendant carried out recovery actions immediately, and the red glow was extinguished successfully,” according to Regional Express’ statement.
After landing, the iPhone was handed over to officials at the Australian Transport Safety Bureau.  There’s no official word yet on what caused the phone to combust.
Exploding Apple products are rare, but explosions have happened in the past, mostly related to the devices’ lithium ion batteries overheating.
The European Union launched an investigation in 2009 after multiple instances of iPhones and iPod Touches exploding or catching fire midflight were reported in the U.K., Holland, France and Sweden.
Apple also  recalled its first-generation of iPod nanos sold between September 2005 and December 2006 because the battery would overheat and “pose a safety risk,” according to the company’s website.
