you should have got a free McAfee virus protect with your laptop, just unistall that, restart your laptop and it works again.
A wireless router takes your Internet connection from your modem and splits it with other computers on your network. The stronger the wireless router the better the signal you will receive. The stronger the signal the further you can be from the router and receive an Internet connection. As good as a strong signal sounds you should consider that your signal can be picked up your neighbors and passers by who may try to access your network.
If the signal is strong enough.
A wireless adapter can lag sometimes when it's signal strength is not that strong.
The strength of a wireless security camera's signal would depend on the camera in question. Some of the wireless security cameras are said to be about 900 mhz.
If you do not see signal from your router, it means that the signal is not strong enough an you need to get a wireless extender or a better router.
your internet connection is not strong enough , try getting closer to the router and it will not say that anymore
It means that the place where you are with your phone does not get strong signal from your carrier.
A wireless extender or more commonly a wireless range extender is a device that increases the range of the wireless network supplied by the wireless router or wireless access point (WAP). It is used by first configuring it to connect to the router/WAP's wireless signal and then it is placed in an appropriate area to help reach parts of the office or home environment in which the signal is too weak prior to deployment of said extender. The best place to set up a range extender is where the signal from the router/WAP is still fairly strong. Typically a signal that is still detected as three out of five bars is fine. Weaker than that and the quality of connection for the remote wireless workstation will not be of acceptable quality to provide decent service.To answer the other part of your question, you are correct. The extender does not need to be plugged into anything other than power. It works with the wireless network over the airwaves just like any wireless device would.If you have any other questions about wireless networking or networking in general, feel free to drop me a line.
You need one wireless router and two desktop computers (one connected let us say with a wire or wireless to working router in one house), and other connected with wireless adapter to the network on the router in the first house ( if signal strength is strong enough). You can protect your network with security key and of course share the key or if you have flat Internet then let it free for everyone. JAKES.
Strong Security
You may have a bad network connection. Check your network settings to see if you are getting a strong enough signal.
Wireless routers connect to the modem through an Ethernet cable and also use a power cord to power the device. The Internet runs through the modem into the router. The router transfers the Internet into WiFi signals that the wireless receiver catches and transfers to the computer. Wireless routers have various signal strengths. The signal strength determines how far you can be from the router and still receive a WiFi signal. the N router transmits a strong signal that can reach throughout your house.
