Does your wireless network seem slow? A recent study by British broadband analyst firm Epitiro shows that their broadband connections offer a 30 percent average data rate reduction when they use Wi-Fi at home. Why slow down? You may have heard that some household electronic devices, including microwaves, baby monitors and cordless phones, hinder Wi-Fi performance. Public Enemy One: Your neighbor's Wi-Fi network "I would say that most of the biggest sources of interference are their neighbors' Wi-Fi networks," Kalle said. The problem is that most existing Wi-Fi devices work in the crowded 2.4 GHz band. "There are basically three non-overlapping channels, and I always describe it as a three-lane road, really busy," Kalle added. If you use a 2.4GHz router and live in a densely populated area, your neighbor's Wi-Fi network may interfere with the performance and range of your wireless network. And if a wifi signal jammer has been used,your wifi will apparently slow or diable. Linksys through Cisco dual-band wireless N Gigabit router solution: buy a work in 2.4GHz and 5GHz dual-band router. While the 2.4GHz band is necessary to support older Wi-Fi devices, the 5GHz "is almost like an 11-lane freeway, nobody knows," Kalle said. "Crowding is much less. Updated Wi-Fi devices, including Tablet PCs, such as the Apple iPad and Motorola Xoom, built-in Wi-Fi Internet ready TV, gaming consoles and business laptops, are dual-band. "They're all in the 5GHz band and they can take advantage of this airspace, which really helps," Culler said. It is important to get support for 2.4GHz and 5GHz routers, such as the $ 100 Cisco Linksys E2500. Some older dual-band routers only allow one band at a time; this is a problem if you have older Wi-Fi devices (most people do this) because you have to leave your router at 2.4GHz. "You will not get any benefit from the 5GHz model," Kalle said. When you buy a new router, look for a dual-band 802.11n MIMO device, usually with the "N600" label. "N" refers to 802.11n, an international Wi-Fi standard approved in 2009. MIMO (Multiple Input Multiple Output) technology provides a wider range by using multiple antennas to transmit and receive data. Quot; 600 & quot; refers to two frequency bands, each transmitted at 300 megabits per second.And now some people may wanna buy wifi jammer to help protect their privacy. 2. Household appliances Does your microwave, cordless phone or baby monitor disrupt your Netflix stream? Maybe. Most of the problems with cordless phones and microwaves involve products that use the 2.4 GHz band. Many baby monitors work at 900MHz and do not interfere with Wi-Fi. However, some wireless monitors are 2.4GHz, which can interfere with 802.11g or single-band 802.11n routers. 3. Bluetooth devices Motorola Finiti Bluetooth Headset Retro Bluetooth devices are interfering with Wi-Fi networks - but those days have passed. "In the past few years, Bluetooth and Wi-Fi manufacturers have implemented specific technologies to minimize interference," Kalle said. Solution: "Most people change phones every two years, so unless you have a genuine old phone or a Bluetooth device, [Bluetooth] can not interfere with Wi-Fi," Kalle said. If you can solve your interference problem, you may not need to purchase a new router. By reconfiguring your router and changing some of its simpler settings, you may find that your Wi-Fi problem has disappeared. We'll show you how to set up the 2.4GHz and 5GHz networks correctly. If you still experience interference or distance problems, you may need some new hardware, but we will cover all of this in the next section.
