Other devices in your home can produce electromagnetic interference (EMI) that can further slow down your WiFi connection. This can include microwaves, some cordless phones, bluetooth devices, TVs, dimmer switches, fans, fluorescent lights, copy machines, treadmills, wireless security systems, wireless speakers, baby monitors, garage door openers, and more. Some of these generate short range interference that can affect your WiFi even when the device is turned off.
- If you have a newer modem, opt for a 5 GHz frequency signal to get a stronger connection and avoid some congestion from surrounding devices, many of which use the 2.4 GHz band.
- Turn off and unplug any devices from the list above that may cause a problem, and test your internet connection. If that fixes your issue, but you still need to use any of those devices, put at least 5-10 feet of space between each device and your modem to reduce interference.
