Optimizing the Router for Better Wireless Connectivity

If you're downloading a large files and it's coming to it's end, you're receiving a Skype call from a client in London, without warning, your Wi-Fi connection drops, leaving your download and VoIP call in havoc. You'll retry the wireless connection, but your router, though blinking contentedly in your tense, seems to be off. After three hour, for no reason, your Wi-Fi connection miraculously resurfaces.

Wireless networking can be a easy and yet gives you a headache, It's great when it works and a mind-numbing frustration when it doesn't. A common complaint among many who have moved to Wi-Fi is that their wireless connection mysteriously fades in and out the frequency.

These steps will help you to create a stable, Always-on the wireless connections.

1. Replace your cordless phone. Cordless phones are among the worst sources of interference for wireless networks. They intend to transmit at a higher power output than Wi-Fi gear, making them louder and therefore harder to talk over, and they tend to transmit frequently, especially when the handset and base station are separated. Some 2.4GHz cordless phones let you select a channel, in which case you can try separating the phone's frequency from the frequency of your wireless network. For example, set your phone to channel 1 and your wireless router to channel 11. If your phone doesn't let you select a channel, try putting some distance between your phone and your router. Generally, it's not a good idea to place a cordless phone next to a Wi-Fi router. If this doesn't help, consider replacing your 2.4GHz phone with a 5GHz phone. This way, your phone and network won't be sharing the same airspace and won't interfere with each other.

2. Expand your wireless network. The farther you are from your wireless router, the greater the potential for interference to block or to slow your connection. For example, you may be able to connect just fine in your house, but on your patio, you may have an intermittent connection that disappears whenever your neighbor is using her cordless phone. The signal on your patio may be too weak to cope with the interference coming from the house next door. You can strengthen the connection with antennas or repeaters or you can use a power-line bridge to import the connection from your router to your patio and feed it into a power-line access point. Instead of the weak signal from your distant router, you now have a strong signal from an access point placed right where you want to buttress your coverage area.

3. Change channels. Interference is a likely cause of intermittent connections, such as the one described above. All 802.11b and 802.11g networks operate at 2.4GHz, in a small swath of spectrum once used primarily by ham-radio hobbyists. Today, these radios, plus other Wi-Fi gear, Bluetooth devices, cordless phones, microwave ovens, baby monitors, and wireless surveillance equipment, all crowd the spectrum. When these devices compete for the same airspace, they interfere with each other, potentially blocking each other's signals. Luckily, there are ways to sidestep and minimize interference in many situations. In the United States, 802.11b and 802.11g devices can be configured to operate at any one of 11 channels. Unfortunately, these channels overlap with adjacent channels, so you have only 3 non overlapping channels at your disposal: channels 1, 6, and 11. If you and your neighbor both have a wireless network, both of which are set to channel 6, you may experience interference. You can remedy the problem by resetting your wireless router to a different, preferably non overlapping, channel, in this case, either 1 or 11.

How a Wireless N Dual Band Router Improves Your Network - Part 1

Part 1: The Cluttered Wireless 2.4GHz Band

Most of today's wireless routers support 802.11g (Wireless-G) and many of them start to support 802.11n (Wireless-N) after the specification has been finalized in October, 2009. If you've bought a laptop or wireless router after 2009, chances are that they will support 802.11n and 802.11g.

Belkin Wireless N Router

belkin wireless n router

Wireless-G and N can both utilize a common network frequency at 2.4GHz, it's the same old 2.4GHz that have been used by earlier 802.11 and 802.11b networks, and also by most of the home & office wireless telephones and remote controls.

With so many devices using 2.4GHz in your house, and your neighbors' surround you, 2.4Ghz networks are extremely cluttered with dozens maybe even hundreds of wireless devices.

To reduce interference to some degree, the 2.4Ghz network is divided up into 14 channels, with each one having its own frequency very close to 2.4GHz. They are 2.412, 2.417, 2.422, 2.427, 2.432, 2.437, 2.442, 2.447, 2.452, 2.457, 2.462, 2467, 2.472, 2.484 Ghz.

In North American only the first 11 channels are used, while in the rest of the world all the first 13, with Japan also using the last channel in their 802.11b standards.

Most 2.4GHz device can choose their channel at one of the 11 frequencies. The larger the difference in the frequency, the less interference the devices will encounter. Setting your device away from a cluttered channel might help a little back in 2003 when not so many Wireless G devices were around.

However, it doesn't really help that much in 2010. By default, all wireless routers choose Channel 6, the one in the middle. If you and your neighbors did not change channel in your routers' setting page, you are stuck in Channel 6 with a lot of other devices. Even if you are smart enough to change to Channel 1 or Channel 11, your laptop probably would still go head-and-shoulder with someone else's devices in the same or a near-by channel.

Unless you live in a big house with a huge backyard, your network environment will be all very cluttered.

Does Wireless-N Help?

The new Wireless-N standards can utilize both 2.4GHz and 5.0GHz frequency bands.

Despite so, most routers that support Wireless-N still don't support 5GHz, and they are using the same old, cluttered, 2.4GHz. Of course, in a perfectly clean environment, you will still benefit from Wireless-N's wider range and faster data transfer rate. But if your router sits in a noisy 2.4GHz environment, it might not perform as well.

This is why so many users still don't feel much of improvement after having upgraded to a Wireless-N router. Their gaming, P2P downloading, transferring files or streaming media are still slow or jerky, or they stop altogether from time to time.

Sure, the router could be overheating or have a flawed firmware, but more likely, you have a noisy, cluttered wireless environment that keeps interfering your wireless communications. It's like a terrible traffic jam on a Friday afternoon, only every day for your router.

Fortunately, Wireless-N supports 5.0GHz, and it's like a whole new open world, where your wireless devices can escape to.

In Part 2, we will discuss how Wireless N dual band router will help you cut through the interference and gives you much higher throughput and range.

So let's have a break and I'll see you in Part 2.

Best Gigabit Wireless Router - What You Need to Know

The term the best for wireless router is relative, because manufacturers always ship new product introductions each several months or so which are better performance and by adopting the latest technologies available in the marketplace.

Today, each of the wireless manufacturers has shipped new wireless routers with gigabit LAN and WAN interfaces for their high-performance category products. Now, which one is the best among those gigabit wireless route products?

Belkin Wireless N Router

belkin wireless n router

Assume you get the best gigabit wireless router today, the next six months or so come a new product introduction with much better performance and the latest technology, who knows. So, in selecting the best one, you should include the following criteria:

1. High-speed. To provide high speed data throughput - the wireless router should be powered with the latest wireless technology - the ratified version of the 802.11n technology. The draft version of 802.11n was approved last Sep 2009 with some option additions.

2. Clean wireless. 5 GHz is cleaner frequency band compared with 2.4 GHz band since wireless router which operates in 5 GHz frequency band is less noise / interference. So, the best router should support the 802.11a technology which operates in 5 GHz frequency band. The router should support the dual-band technology.

3. Further range. So far, the technology adopted for the wireless devices to deliver longer distance range is the MIMO (Multiple-in Multiple-out) technology combined with wireless N. Some manufacturers do not specifically specify the MIMO technology in their products but they adopt the technology into the products.

4. Consistent data throughput. High-intensive bandwidth applications such as gaming and video streaming demand consistent data throughput for lag-free and jitter-free performance. Your best gigabit wireless router should support the Quality of Services (QoS) technology for multimedia traffic prioritizations.

5. Secure. Mostly all new wireless routers today are powered with the latest security technology including the WPA/WPA2; NAT and SPI firewall; VPN pass-through; and the new feature option is the capability of providing a security boundary for guest access. Typically the router supports the multiple SSID for secure guest access. Guest access is ideal for your SOHO environment where you allow your business visitors access the internet without providing your private network resources.

In selecting the best gigabit wireless router, you should examine that the router support the above criteria for high-performance wireless network.

The following list some of the best gigabit wireless routers - the new product introduction from the leading wireless networking manufacturers:

DIR-665 D-Link Xtreme N450 Gigabit Router
