Answer:
Crosstalk, Jitter, Impulse noise.
Explanation:
Crosstalk is a network error that occurs when one pair of cable causes interference on another pair of cables thereby preventing efficient data transmission.
Jitter may also impair the accuracy of the data being transmitted across network because minute variations in amplitude, phase, and frequency always occur. The generation of a perfect carrier signal in an analog circuit is almost impossible. The signal may be affected by continuous and rapid network gains or phase changes.
Impulse noise (also referred to as spikes) is the primary source of errors in data communications. Impulse noise can be caused by positioning a communications cable near a source of intermittent but strong electromagnetic pulses, such as an elevator motor.
Counter measures
Shielding (protecting wires by covering them with an insulating coating) is one of the best ways to prevent impulse noise, cross-talk.
Amplifiers can be used to increase signal strength since the connection would run across 4 floors.
Answer:
You can open the version of your computer or device from the task manager to see the running programs and close the application
Explanation:
Right-click on the Windows Start menu and choose Task Manager (another way to open it is to press the keyboard shortcut Ctrl + Alt + Delete and select it from the options that appear).
NOTE: Click here if you don't know how to display Windows 8 Start.
You will see the main Administrator window (as in the image above). Displays a list of the programs that are currently running.
Find the application or process you want to close. Click on it with the RIGHT button and choose End task. In some cases a notice appears asking you to confirm it. Read what it says to know the consequences of forcing it. Confirm if you are determined to do so.
IMPORTANT:
There are viruses, adware or other spam programs that you may not be able to close even in this way. For these cases follow this link on how to clean viruses without entering Windows.
When you're done you can exit the Task Manager window. Click here to close background applications.

Answer:
Check below for the explanation
Explanation:
The following suggestions will be given to the customers:
- Go to network settings and check the WIFI settings to confirm whether the WIFI connection is on. Switch the WIFI to the on position if it is off.
- The customer should check if the wireless driver is installed on the computer, if the driver is not installed, he should try to install it
- The customer should check all the available access points and confirm if their signal strengths are strong enough to allow for any connections. Restart the access point to enhance proper connection.
- Check to see if your operating system is updated to support your internet connection. You can update your operating system to the latest version
- Run a Network Diagnostics on your computer. This will run a couple of tests to see what’s possibly causing your Wi-Fi issues.
