    How to Boost a Router Signal

    29 authors | 89 revisions | Last updated: October 25, 2012



    Article Edit Discuss
    A wireless router typically has a range of 100 feet or more. However, there are many factors that can lower this range and zap its signal strength. Interference can be caused by metal, competing signals and other devices that use wireless frequencies (like cell phones and microwave ovens). Thankfully, there are many methods available to boost your signal strength. Here are a few.

    Edit Steps

    Look for Interference

    • 1
      Replace devices in your home that can interfere with network traffic on the 2.4GHz frequency range. You can buy a wireless network analyzer to help you track down the source of interference. A sample of appliances that might be causing the problem include: Ads by Google

      • Cordless phones,
      • Microwave ovens.



      • Baby monitors.
      • Security alarms.



      • Television remote controls.



      • Automatic garage door openers.




    • 2
      Check your router's signal strength with these devices. Compare power levels when each device is on and off to determine if they are the cause of your signal problems.

    Switch Channels

    • 1
      Change your signal channel. Routers can broadcast on a series of channels, between one and eleven. Change to a channel that will allow your router a clear signal between other wireless networks.



    • 2
      Use a software utility to analyze which networks are using which channel and configure your system for an unused channel.

    802.11n

    • 1
      Change your router's network broadcast mode. Try to use the new 802.11n standard if your router supports it. The 802.11n standard offers far greater range and signal strength compared to 802.11 a/b/g.




    Relocate

    1
    Reposition your Router. Sometimes the solution is simple. All you have to do is find a new place to store your router.





    • Raise up as far as possible to increase the effective broadcast range.



    • Place near the center of your house or apartment for wider coverage.

      • Move closer to the receivers, if possible.



      • Move away from any metal including metal shelving, filing cabinets and similar common objects.



      • Move away from cordless phones and microwaves, which operate on the same 2.4-Ghz frequency.




    • 2
      Be aware of external interference. Move your unit as far away as possible from your next door neighbor's Wi-Fi router. And if you're living in an apartment building, there might be multiple routers in operation too. Note: make sure you're using a different channel than everyone else.

    Upgrade

    • 1
      Raise your transmit power. Check your router's documentation and configuration utility for the ability to change the Xmit power of your router: the amount of power it uses to transmit the signal. Generally you can boost this number by up to 50mW. Keep in mind that you risk overheating or damaging your router.



    • 2
      Replace the Antenna. Unscrew and replace the broadcast antenna on your router with a model that delivers more power. Not all routers allow for new antenna to be attached, but many do.



    • 3
      Install a Repeater. A repeater is a piece of hardware that acts like a wireless network expander. The repeater takes the signal from your router and boosts it to increase the range.





      • Wireless repeaters are increasingly common and affordable and will probably be available in your local computer store, or on the Internet.

    • 4
      Install a Wireless Amplifier. Attach a wireless amplifier, also known as a booster, directly to your router. A booster can be more affordable than a repeater as they only increase the strength of your existing signal, rather than the strength and range.





      • Use a bi-directional amplifier to increase both your inward and outbound speeds.

    • 5
      Make a Reflector lulu with Tinfoil. Note that a tinfoil router may boost your signal, but will also make it more directional.





      • Cut a tinfoil circle with the tinfoil on the inside of a piece of paper or some cardboard large enough to wrap around the router. If you want to get fancier than this, cut a shallow parabola and put the hole for the antenna at the focal point.



      • Place the tinfoil circle over the router.



      • Place the antenna in the center of the circle or parabola.

    Chosse D-Link DIR-655

    by oscar2chat - 9/30/11 1:33 AM

    In Reply to: Which wireless router has the longest range? by prepster2009

    I own a D-Link DIR-655 router and I am across the street from my brother's house which is where I connected my D-Link DIR-655 router so it can transmit a signal to me. Where I am is located probably 150-200 feet away, i believe it is pretty far. I get up to 52 Mbps. The router is capable of 300 Mbps but it usually connects at 65 Mbps to 135 Mbps if you are near and if the correct setting are right.

    Newegg has a great deal on D-Link DIR-655. I bought it there and have been very satisfied with that little white N Router. By the way, it is a b/g/n router.

    khoảng cách bắt sóng chỉ được chừng 30 feet thì quá tệ. Có lẽ cái Dir 655 của bạn có vấn đề.

    Bạn thử reset lại router hay check for newest firmware.

    hay
    Dùng Range-Extenders

    Người quen tui đang xài của Hawking, good.

    Nếu không cần nhiều connections thì nên mua powerline, way better than wireless

    ...
    Lại là bạn,
    Bạn có lẽ biết tôi nhưng tôi không nhận ra bạn là ai. Bạn có vẻ rất giống nhiều người, chỉ hy vọng bạn không phải là những người tôi muốn đứng ... càng xa càng tốt.
    Tôi chưa thử reset lại router hay check for newest firmware. Nhưng qua câu bạn post tôi có thể hình dung được sự việc. Và hình như đó là những việc rất trẻ con.
    Dù sao cũng cám ơn bạn.
