- Check for interference
- Replace devices in your home that can interfere with network traffic on the 2.4GHz frequency range. These devices include many cordless phones, microwave ovens, and the like.
- Check your signal strength with these devices on and off to determine if they are the cause of your signal problems.
- Buy a wireless network analyzer to track down the source of interference.
- 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.
- Configure your system for an unused channel.
- Reposition your Router.
- Raise the router up as far as possible to increase the effective broadcast range.
- Move the router away from any metal including metal shelving, filing cabinets and similar common objects.
- Move the router closer to the receivers, if possible.
- 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, however you do risk overheating or damaging your router.
- 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.
- Install a Repeater.
- Purchase 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.
- Install a Wireless Amplifier
- Purchase and 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.
