It does not matter where the router faces as long as you reside on the same premises. However, what matters the most is the model and technology installed in the router as well as ideally having several antennas.
As a general rule, if you've placed your router upstairs to try and achieve a stronger signal across two floors, it's best to turn the antennae sideways, and if it's placed on the ground floor, its advisable to turn your antennae upwards.
The ideal position for a wireless router, then, is in a central location. Placing your router in the center of your home reduces wasted coverage area and eliminates unnecessary distance between the unit and any connected devices on the outside edges of the coverage area.
Yes. So long as you provide adequate air space and there is adequate air flow in to the area, you should be fine.
Routers tend to spread signal downward, so it's best to mount the router as high as possible to maximize coverage. Try placing it high on a bookshelf or mounting it on the wall in an inconspicuous place.
If you're trying to get your signal to spread horizontally, positioning your antenna vertically will give you the best spread. If you're trying to get the Wi-Fi to broadcast between floors in your home or office, position the antenna horizontally.
In theory, Wi-Fi signals are capable of passing through walls and other obstacles relatively easily. However, in reality, some walls are thicker or use reinforced concrete and may block some of the signals. Materials such as drywall, plywood, other kinds of wood and glass can be easily penetrated by wireless signals.
How Far Should a Router Be From a TV? Your Wi-Fi router should be five to six feet from your TV. As a rule of thumb, place your Wi-Fi router at least five to six feet (1.5 to 1.8 meters) away from your TV and any other devices which could interfere with the signal, such as your microwave.
In two-story houses, the best place to put your router is often on the ceiling of the first story or the floor of the second story.   These two places often allow for the best wireless connection, as they are a very central location for both levels of the home.
If your wireless router is against an outside wall of your home, the signal will be weak on the other side of your home. It is better to place the wireless router on a table or shelf and keep it at a certain height so that the omnidirectional antenna's transmitting ability can be utilized.
Put your router in an open space, preferably higher up (because Wi-Fi signals travel outwards and slightly downwards). Make sure there are as few obstructions as possible between the router and the areas where you need the best internet speed and reliability.
Weak Wi-Fi signals could be caused by the following: The router is too far away from your device. The router's Wi-Fi transmit power is not strong enough. There might be intervening barriers (e.g., a large expanse of metal) blocking the Wi-Fi signals.
Concrete, with and without metal reinforcement, is one of the worst building materials for wireless signals to pass through, but masonry block and bricks can also be serious barriers for Wi-Fi.
Non-wifi technologies using this band (microwaves, Bluetooth, etc.) or the neighboring WiFi access points using overlapping side channels create interference.
Don't put your router on the floor. Get your router off the ground at least 5-7 feet if possible. It's kind of like a light bulb; when you turn it on you want it to shine as far as possible, not straight into the ground.
Yup you can lay it on it's side. Does not change anything.
Lift It Up – We recommend you place your router five to seven feet off the ground with a clean line of sight. Your router emits radio waves that spread out and down from their source. Placing your router a good distance off the ground improves the range of your signal.
Check to see if moving your device closer to your router helps you connect. If you normally have a strong signal in rooms far away from your router but suddenly can't connect, take your device closer to your router. If it can pick up a signal in a closer room, you may need a Wi-Fi extender.
WiFi hotspot strength is insufficient – you may be near the edge of the WiFi network. WiFi network is overloaded – happens in crowded areas – on the street, stadiums, concerts, etc. Wireless interference with other WiFi hotspots or devices nearby. WiFi adapter outdated drivers or wireless router outdated firmware.
Moving just the router can be a good option if you can't install a coaxial or phone cable in the new room, but you can install or already have installed an Ethernet cable in the new room.
A modem is a box that connects your home network to your internet service provider, or ISP. A router is a box that lets all of your wired and wireless devices use that internet connection at once and allows them to talk to one another directly.
