Interference from electronic devices can reduce wireless network range by up to 30%. To improve range, install the router away from other devices, change channels, use a high-gain antenna, or upgrade to a newer model.
If you have a wireless network set up in your home, you know that getting perfect reception can be tricky. Things like the simplest electrical devices can cause enough interference to reduce the range of your wireless network by up to 30%. You can improve your range by installing your router away from other electronic devices, changing the channel, and using a high-gain antenna.
First, make sure your wireless router is installed in a central location, preferably mounted on a wall and as far away as possible from other devices that also operate at 2.4GHz, such as microwave ovens, bamonitors, and cordless phones. Bluetooth® gadgets can also cause problems and affect the range of your wireless network. Anything from closed doors to weird angles can cause interference, so try to install your wireless router as close to the source as possible. Metal objects in general can also cause interference, as can windows and electronics.
Once you’ve found the perfect spot for your wireless router, try switching channels until you find a frequency that works. Most routers are preprogrammed to operate on channel 1 or 11, but they can operate on other channels without problems as well. If you suspect that your neighbors may also have wireless routers in their homes, it’s possible that the interference is coming from them. Try different channels before settling on one.
If all fails, consider replacing the original antenna that came with your router. A wireless network range can benefit greatly from a high-gain antenna, which directs all signals in a particular direction, rather than a standard antenna, which is omnidirectional. An omnidirectional antenna can often divert signals towards walls, which reduces the router’s capacity. You can also consider adding a wireless repeater, which simply boosts the signal when placed between your router and computer, resulting in better reception.
Sometimes, you have no choice but to upgrade your router if you want to dramatically improve its range. Older Wi-Fi routers have an output of 11 megabits per second, while newer models can reach 280 Mbps.
