Wireless Router Repeater

Use a Wireless Router Repeater to Extend Your Wireless Network

A wireless router repeater is a device that can extend the range of a wireless network by amplifying and propagating the signal strength of the originating wireless network.

Wireless router repeaters basically receive data packets wirelessly and retransmit them at full power. This allows you to extend the range of a wireless network. But there is a tradeoff. The bandwidth speed of the wireless network connection will drop in half. That's because the signal is received and retransmitted. This may not be a problem if the top speed of the wireless network is very fast. Some wireless router repeaters can be challenging to setup for the novice user. Most wireless router manufacturers have a model designed as a combination wireless router repeater that is sold as a pre-configured device out of the box so non-technical people can set them up easily. But most of these devices will also have proprietary firmware that will only work with the same brand devices for a wireless repeater.

If the distance of your wireless network does not reach your intended computers, a repeater can increase the workable range of your wireless network and may be the only suitable and affordable option for the area of coverage you need. It is important that you place the wireless router and wireless repeater within locations that allows their wireless signals to overlap otherwise they will not work together.

Best Range Wireless Router

Want to extend the range of your wireless router?

Extending the range of your wirelss router can be done quickly and easily with the use of a hi-gain wireless adapter for your computer. Hawking Technology in the USA, a manufacturer and marketer of connectivity solutions, has developed a new wireless adapter for computers that makes standard routers perform like the best range wireless routers.

What Factors Affect a Wireless Router Range?

The range of a wireless router depends on a number of factors such as the power output of the wireless router, the gain of the antenna, the number of physical obstacles between the wireless router and your computer and the speed of the connnection. The further your move away from your wireless access point, the less reliable your the wireless connection will be. One method to extend the range is to buy multiple wireless routers or access points to extend the coverage. Unfortunately, this costs more and adds to the complexity of the setup and configuration.

The Best Hi-Gain Wireless Adapter

Enter the new Hawking HWDN1 Hi-Gain Wireless-300N Network USB Dish Adapterhttp://www.assoc-amazon.com/e/ir?t=router3-20&l=as2&o=1&a=B0015FGXZU from Hawking Technology. The 300N can boost the range of wireless connectivity with your wireless router by a factor of 6 and the throughput by a factor of 12. This best range wireless router combination uses a built-in dual antenna that concentrates the wireless signals which extends the typical wireless range by up to 600%, compared to a standard wireless router and adapter. The device is also capable of throughput speeds of up to 300Mbps making it very fast compared to some of the earlier 802.11 standards. The 300N best range wireless router combination will also support WEP, WPA, and WPA2 security features to ensure you can secure your connection.

Simple to Setup

The best range wireless router combination using the 300N is simple to setup. Just load up the software from the CD and connect the dish adapter to your computer through a spare USB port and direct the dish towards the wireless router access point.

Wireless Router - How to Buy One

     It's hard to imagine a modern home or business network without a wireless router, but that doesn't mean it's easy to pick the right router. Our guide can help you pick the best one for your network.

     Routers are an essential element of modern business network, and they're an indispensable tool in the home, too. A wireless router lets your computer connect to the Web so that you can read favorite Web sites, check e-mail, IM friends, or teleconference with colleagues. If you want to do this without cluttering your setup with Ethernet cables, a wireless router is a must. And, if it's your first time going wireless, don't worry about giving up wired speed. All wireless routers offer at least some degree of wired connectivity, allowing you to get the best of both worlds.

The wireless router market offers many different types of routers that are tailored to tackle specific needs. Vendors offer everything from very basic single-band routers designed to simply get your computer online to advanced dual-band routers that contain bonus features (such as a built-in digital photo frame). With numerous models, options, and offerings available, purchasing a wireless router is no simple affair. You may need to research the features in order to wade through the marketing hype in order to determine which router is best for your home or home office. Our wireless router buyer's guide will help you do just that.

Determine Your Usage

A single home user who just wants to Web surf doesn't require the same type of router as a heavy-duty gamer or small business. A single-band router like the $149 Cisco Valet Plus is a basic, decent performer that would suit the needs of anyone looking for simple Wi-Fi connectivity and easy setup. By contrast, the $359 D-Link Xtreme N Duo Media router has power-user features such as Traffic Prioritizing; Virtual Servers and UPnP support. The Xtreme N is likely to be more of value to gamers, multimedia enthusiasts or anyone with advanced networking needs. A good rule of thumb: The more expensive the router, the more features it will contain. Higher price, however, doesn't necessarily mean better performance; in our testing, the Cisco Valet Plus performed just as well as pricier, more feature-rich routers.

Single Band vs. Dual Band

While researching routers, you will inevitably stumble across the term "bands". The 2.4- and 5- GHz bands are the frequencies in which wireless communications operate. 802.11 B and G standard devices use the 2.4 GHz band, while 802.11N can use either the 2.4 GHz or 5 GHz band. A single-band, 2.4-GHz router, like the $65 Asus RT-N11 EZ wireless-N router is geared toward simple wireless networks. On the other hand, a dual-band router like the $119 Cisco Linksys E2000 Advanced wireless-N supports both 2.4- and 5-GHz frequencies. The 5-GHz band is better equipped for throughput-intensive work within your home network such as gaming and file streaming. In fact, as mentioned in our "Setup and Small Home or Business Network" article, you will also get better internal network performance.

 Know Your Standards

     Knowing which standard the majority of devices on a network support is important in deciding which router is best for your setup. For example, if you want to connect two slightly dated laptops which house 802.11b/g wireless cards to the Internet, and you have no need or plans to upgrade your client devices anytime soon, you could get away with a cheaper, single-band 2.4 GHz 802.11N router. Why? You can run the router in "Mixed Mode" setting, which will let the router connect to B and G clients. Secondly, only N routers can connect at the 5 GHz band, so you only need a 2.4 GHz router for B and G clients. A decent option would be a router like the Cisco Linksys E1000 wireless-N router, which is available for under $60 (if you can swing the extra $70, however, the Valet Plus is the better option).

     If you have a mix of B, G and N devices (as most of us do), your best bet is to go with a simultaneous dual-band router like the $169 D-Link DIR-825 Xtreme N Dual Band Gigabit. This model excels at automatically connecting devices to the appropriate band, without user intervention. There are other dual-band routers that are good choices as well, like the $119 Linksys by Cisco Dual Band wireless N Gigabit router. This model requires user to be savvy enough to know how to configure settings so that all devices (be they B, G or N) can connect to the correct 2.4-GHz or 5-GHz band.

PC vs. Mac

     We have tested numerous wireless routers from a variety of vendors, and have determined that it the make or model makes little difference on a Windows network. There's some anecdotal evidence from readers and the blogosphere that a network consisting of all Apple products works best with an Apple router. Many chimed in on an article about iPad Wi-Fi connectivity. Several readers stated they had none of the connectivity problems with their iPad when connecting it to an Apple AirPort.

     Routers should theoretically work across the board for Windows, Apple and Linux clients. If you have an all-Apple or predominately Apple environment, save yourself any potential hassle and go with a router from Apple.

Coverage Area/Antennas

      Router antennas can either be external or internal, with the former seemingly delivering stronger signals. One of the fastest Wi-Fi routers we have tested is the $79.99 D-Link DIR-825 Xtreme N Dual Band Gigabit, which has two external antennas. In some cases, it's possible to purchase signal amplifiers or upgrade the antenna to one that's more high-powered. The one drawback with external antennas is that they can be more problematic to discretely situate in a home than a router with internal antennas such as the Linksys Ultra RangePlus wireless-N router, which is built with Linksys/Cisco's familiar sleek design. Also, it's true that anything that sticks out can be broken off.

Accordingly, don't discredit routers with internal antennas. For most home purposes, new routers like the $179 Cisco Linksys's E3000 High Performance wireless N router have an almost unheard of 6 internal antennas with 2x3 transmit/receive. We have not tested the router yet (look for the test soon) but the E2000, which is the mid-router in the E series, was a decent performer that only has 3 internal antennas.

Keep in mind, despite whatever the antenna design is, large areas may sometimes need more than one wireless router for coverage. The average range for wireless coverage is 180 feet max indoors and 1,500 feet max in an open space—that's devoid of concrete walls or any other interference!

Feature Set

     Most wireless routers have some basic functionality; port forwarding, DHCP, firewall and NAT are a few of the features inherent in just about every router within the last three years. There are routers with lots of extra features for advanced users, like the $129 Belkin wireless PlayMax router. The PlayMax has features like Guest Access, Channel Bonding (to boost wireless signal), Access Control and a Bit Torrent client. While we can't recommend the Play Max at this time, (further testing on it is to follow) because of underwhelming performance, the features set is truly impressive and is one that should appeal to avid gamers, torrent users, or even small businesses.

     Some routers have USB ports for connecting a printer or storage device, the D-Link Xtreme N Storage router. Not only does it have USB ports, but it has a slot for 2.5-inch SATA drive and doubled as a digital photo frame. This may not be a router option for anyone, but if you have additional networking needs and may be low on space on ports to connect extra devices, a fancy router like the Xtreme N Storage may be a good bet. Prepare to shell out some cash as this router listed for $300.00 at shipping.


     Most routers currently support standard WEP security as well as the more secure WPA and WPA2. If you want to control what users can access when they are connected to the router, you are doing to want one that offers decent Access Controls. Cisco's Valet Plus has very effective Access Control settings plus Parental Controls that allow limiting internet use based on time of day. Guess Access and an ability to create multiple SSIDs are also important security measures if you are using the router for a small business. Together, these two features let you, for example, segment your network into seperate areas for guests and trusted users.

Wired Connectivity

      Most wireless routers have Ethernet ports for hard-wiring devices to can take advantage of the greater transmission speeds that wired Ethernet has over a wireless connection. For faster transmission rates, invest in a router that has Gigabit Ethernet ports like the Netgear RangeMax wireless-N Gigiabit router. Use the Gigibit Ethernet ports to wire gaming consoles, NAS drives, or any other type of multimedia server that have Gigabit Ethernet adapters to take advantage of the faster performance.

wireless routers

If you’re looking to buy the best wireless router, there are certainly a few things you need to know before you buy. There are many wireless routers out there and many of them claim their router is the best, but how do you actually know which one is right for you and your internet connection?
What system is running on your personal computer? Do you have a PC or MAC?
I am asking you this, because these are two completely different systems and they both need a different wireless router in order to run properly. So, first decide which one would you personally need. Then, make sure you don’t just look for the cheapest wireless router, because there’s a saying that goes something like: “What you pay for is what you get” or something along those lines, but you get my point, right?
Will you be using this for you own personal use or for your company?
Because there is a difference and you need to pick the right one in order to have all this properly setup. How many computers will be hooked up to this wireless router? One, two or more? There are many different routers that will fit your needs and again, don’t just go for the cheapest wireless router, because it may turn out you’d need to spend more money later on and i guess that’s not something you want to do am i right?

This wireless router is one of the best you can find, it is compact and can be used for both, desktop and laptop computers. And you can always buy additional firmware and make this router work even faster and better, but that’s optional. I never needed to buy anything for this router to work the way i need. It just works out of the box, so you don’t need to be a hacker in order to bring the most out of this wireless router.
Choices -- Wireless routers with Internet connection sharing, networking and firewall features are an alternative to Wired routers or Networking Software. Wireless routers are actually wired routers with wireless access points built in so you can have wired and/or wireless at the same time. Another choice is a wireless router with a built-in DSL or cable modem. Finally, you can consider a hardware and software security combo box to connect and protect your home network, see our Broadband Gateways page for more information.
Security -- wireless routers are not as secure as hard wired. If you want wireless and security, read the security articles on this page and be prepared to spend some time setting up the security features of your wireless network. To make this easier, look at getting started and wireless utility software.
Testing -- We recommend that you test the firewall features of a wireless router after installation and setup using an online service like Security Space.
Firmware -- Router vendors offer updates for their firmware to add new features and to resolve problems found by their customers. After installing a new router or updating to Windows 7, check for updates.
Prices -- For current prices, see our custom wireless routers Price List powered by Amazon.com or click on one of the products pictured below. We also have a list of vendor discount sale offers.

IPSEC FBI accused of planting backdoor in OpenBSD IPSEC stack

In an e-mail sent to BSD project leader Theo de Raadt, former NETSEC CTO Gregory Perry has claimed that NETSEC developers helped the FBI plant "a number of backdoors" in the OpenBSD cryptographic framework approximately a decade ago.

Perry says that his nondisclosure agreement with the FBI has expired, allowing him to finally bring the issue to the attention of OpenBSD developers. Perry also suggests that knowledge of the FBI's backdoors played a role in DARPA's decision to withdraw millions of dollars of grant funding from OpenBSD in 2003.

"I wanted to make you aware of the fact that the FBI implemented a number of backdoors and side channel key leaking mechanisms into the OCF, for the express purpose of monitoring the site to site VPN encryption system implemented by EOUSA, the parent organization to the FBI," wrote Perry. "This is also probably the reason why you lost your DARPA funding, they more than likely caught wind of the fact that those backdoors were present and didn't want to create any derivative products based upon the same."

The e-mail became public when de Raadt forwarded it to the OpenBSD mailing list on Tuesday, with the intention of encouraging concerned parties to conduct code audits. To avoid entanglement in the alleged conspiracy, de Raadt says that he won't be pursuing the matter himself. Several developers have begun the process of auditing the OpenBSD IPSEC stack in order to determine if Perry's claims are true.

"It is alleged that some ex-developers (and the company they worked for) accepted US government money to put backdoors into our network stack," de Raadt wrote. "Since we had the first IPSEC stack available for free, large parts of the code are now found in many other projects/products. Over 10 years, the IPSEC code has gone through many changes and fixes, so it is unclear what the true impact of these allegations are."

OpenBSD developers often characterize security as one of the project's highest priorities, citing their thorough code review practices and proactive auditing process as key factors that contribute to the platform's reputedly superior security. If Perry's allegations prove true, the presence of FBI backdoors that have gone undetected for a decade would be a major embarrassment for OpenBSD.

The prospect of a federal government agency paying open source developers to inject surveillance-friendly holes in operating systems is also deeply troubling. It's possible that similar backdoors could potentially exist on other software platforms. It's still too early to know if the claims are true, but the OpenBSD community is determined to find out if they are.
