How to Strengthen WiFi Signal
Use Free Virtual WiFi Router to Extend WiFi Range
First of all, you can use our Free Virtual WiFi Router as a repeater. If you have WiFi connection on your laptop, just download Free Virtual WiFi Routerand follow the tutorial to share the WiFi by creating another hotspot. Thus you can make your laptop a WiFi router to repeat the WiFi signal so that you can put it in an ideal place in your house to get WiFi range extended.
Look for Interference
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 cordless phones, microwave ovens, baby monitors, security alarms, Television remote controls, automatic garage door openers, etc. 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.
Reposition Your Router
Sometimes this solution is the easiest - all you have to do is find a new place to store your router: raise 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. Meanwhile, you should be aware of external interference. Move your unit as far away as possible from your next-door neighbor's WiFi router. If you're living in an apartment building, there might be multiple routers in operation too. Make sure you're using a different channel than everyone else.
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.
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. Use a software utility to analyze which networks are using which channel and configure your system for an unused channel.
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.
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.
Install a Repeater or Wireless Booster
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. Meanwhile, attaching a wireless booster, also known as an amplifier, directly to your router, can be more affordable than a repeater as it only increases 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.
