check whether you have assign IP address for the wireless network manually or not. if you are given IP manually it won't detect any of available networks and you will not able to connect to wifi networks. just go to network and sharing center ( you can right click on network icon in the taskbar and open network sharing center then select your wireless network,
then select properties > go to TCP IP V4 and V6 setting and give select obtain IP address automatically. then it will detect the new wifi network and if the wifi network are secured you will ask for the password to connect to it. by giving the password of the wifi network you can connect to your wireless network.
in all laptops you will find a wifi button please be aware to switch on your wifi button before you connect.

The laptop could be out of range of the source of the wireless signal; otherwise maybe either the wireless source or receiver could be turned off.
Wireless televisions are those that do not require being connected by cable to an aerial or digital box to receive a signal. They pick the signal up through a wi-fi set up, similar to that used by wireless PCs and laptops.
The detector detect the audio signal in the received modulated RF signal, rectify it and filter the RF to ground and pass the pure audio to the next stage
Some wireless signals cannot be picked up by some mp3 players. In that case you will have to get a wireless signal booster. Hopefully that will help
Wireless routers are required to have a wireless network connection. The stronger the wireless signal the further the signal will reach. Although the network can be seen by others within it's signal range, for security reasons your network cannot be accessed without a network key. Specifically a N rated wireless router has a powerful signal. G routers are much less powerful. For any router to work you need to connect a wireless receiver to the computer you want on the network.
Sometimes signals from different wireless devices might conflict. But usually a wireless mouse cannot confilct with a wireless network adapter (however, it's possible). You have read the manual for the mouse and check on which wavelength it operates. After you have read the manual you will know the frequency or frequency range and it will be easier to understand where you can get problems.
This is actually coming from your monitor. I am assuming you cannot get a picture on your screen. It is telling you it cannot detect any input signal. You just need to check where the monitor cable is plugged in and ensure its in the right spot.
You can get so called wireless boosters or extenders. They allow to cover longer distances and make internet accessible in areas where your router cannot provide a signal.
It you can pick up Internet signal without hooking an ethernet cord into your computer. You can get the wireless signal in the wireless routers range.
make sure she has the right internet protocol (IP) address
You could attach an external directional antenna. Google for 'wireless antenna'.
Carrier signal is of high frequencies, it gives strength to the original signal because original signal cannot travel long distances so it needs to be strengthen a bit for transmitting. The carrier signal is a high frequency signal, called an RF. Radio Frequency signal, it is to high for the human or animal ear to detect it, so its outside the audible spectrum and can easily be transmitted over the air to receivers that is tuned to receive that frequency and detect any modulation on that signal.
No, With most wireless cameras; they rely on a wireless routers signal to work.
