is wifi affected by walls?
449637
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.

If your router is on the ground, many of your Wi-Fi signals will travel horizontally along the floor and reach fewer parts of your home. You may be able to improve the signal and raise your internet speeds by setting up the router on the second floor if you have a multi-level home.

WiFi extenders help extend the WiFi signal further out from your Gateway; however, due to their limited range, they will not extend WiFi coverage throughout the entire home. Note: The devices that are connected through your router/extender may not appear in xFi.

Your laptop's WiFi speed is slow because it's too far from the router. Usually, walls, big objects, and other things that use radio frequencies can mess with WiFi. If that doesn't solve the problem, update your driver software and reset router configuration to factory default.

The digital TV signal is a 'line of sight' signal. Typically, the higher you have your antenna, the better the reception. While signals pass through walls and other surfaces, the more obstructions the signal encounters, the weaker the signal and this causes signal disruption.

Interference is by the far the common problem but also how WiFi is setup can cause problems. Making Router and Extenders the same SSID network name, Make it Easier but can create a roaming issue with cheaper routers: ... Many people have complained over the years about this as they want seamless wifi.

ALL YOUR WIFI ARE BELONG TO US – WiFi Security Broken by KRACK. ... The vulnerability is in WPA2, the encryption protocol that virtually all WiFi devices and networks in the world use. Mathy Vanhoef and Frank Piesons at IMEC-Distrinet Research Group, Ku Leuven discovered this vulnerability and it is a doozy.

The rediction in wifi spees at night is most probably due to interference from your neighbours. You could try changing the 2.4GHz wifi channel try ch1,6,11,3 or 9 to see which gives the best results.

You are unlikely to run in to an issue. It does increase noise on the line, but if you are well within spec on the run (IE less than 100 meters) and don't have any major noise generators in the frequency range that ethernet operates at, it should be no issues at all. IE don't worry about it.

If you only have a few Wi-Fi devices in your house, you may want to unplug or turn them all off, and then watch the wireless signal light on your router. If the light continues to flicker, someone else is using your Wi-Fi.

WiFi operates in the 2.4 GHz frequency range, the same as a microwave oven. The wavelength of that light is about 12.5 centimeters, which is about 125 million nanometers.

Music or Media Not Playing with Alexa. Wi-Fi connectivity issues can cause media and music to buffer or not play. ... Reduce Wi-Fi congestion by turning off any connected devices that you're not using. Move your device away from walls, metal objects, or sources of interference like microwave ovens and baby monitors.

WiFi is a radio signal that continually broadcasts out to your devices. As long as your device can pick up that radio signal, and the Internet is on the other side of it, your device can connect to the Internet. However, that radio signal will still be there even if there is no Internet connection on the other end.

Another way to tell, is to look at your Wi-Fi network's name (SSID). Your Wi-Fi router may be broadcasting two networks, with different names to indicate the 2.4 GHz and 5 GHz bands. ... For instance, the 5 GHz network may have 5, 5G, or 5GHz as part of its name.

Wireless networks are vulnerable because they transmit data on radio signals, which pass through walls. Just as anyone with a scanner can eavesdrop on unscrambled police radio chatter, intruders with the right equipment can intercept wireless data transmissions in and around your facilities.

Slow WiFi can be caused by many factors. The common culprits behind a lagging WiFi connection include too many devices connecting to one channel, users doing bandwidth-heavy activities, the way your router is positioned, and outdated hardware and drivers.

The easiest way to tell is to go to your router Web site and look up your connected devices. If the Mac address of the Tablo matches what is printed on the Tablo, then it is wired. If it doesn't match, then it is using WiFi.
