Try to avoid placing your wireless networking devices near these:
External monitors and LCD monitors – Some display monitors can generate a wireless interference with a WiFi network. More specifically it may interfere with 2.4 GHz networks. If you can’t avoid these monitors, we suggest you try to lower your WiFi channel. (Example: instead of channel 11, try 6 or 1 instead.) Or even better, connect to a 5 GHz network.
Other wireless 2.4/5 GHz band devices – Cordless phone, Bluetooth devices, both of these may create interference on your WiFi network.
High powered sources – Avoid breaker boxes or large power lines that are nested in walls.
Satellite service – If you have a coax cable connected to a satellite service, ensure that your coax cable is shielded properly. If you find wear and tear on the cable, we strongly recommend replacing it!
Low quality cables – Some cables are not shielded properly and may create static interference with the WiFi network. You may want to check any electrical cables that seem worn down.
Microwave – Turning on microwaves can cause interference for your WiFi network. When possible, avoid connecting near it or through it.
Certain building materials – Water, bricks, marble, plaster, concrete, and metal may block or lower your WiFi network signals.
