1) Power cycle the system by shutting it down and switching it back on after 30 seconds.

2) Check the network settings in order to verify the IP address and other related information.

3) Determine whether your network card is working adequately.A way to identify a malfunctioning adapter is by disabling the cards one by one.

4) Try moving a portable host (e.g ypur laptop) closer to the router. If it works better, interference of low signal strength is the reason for the poor internet access.

5) Remember to check the functionality of the wireless router and access points. Adjust the antenna to get an optimum signal.Most wireless routers should come with omni-directional antennae to send signals in all directions – a situation appropriate for a square shaped network.

6) Try changing the location of the router and access point. Ideally they should be placed central to all of the computers.

7) Examine signal performance by using the monitoring utility that typically comes with the access point.

Check your devices are showing the correct lights. There is no universal standard to indicate wireless router functionality so make sure that you check the devices manuals to see which lights indicates what function.

9) Use wireless internet connection utilities to check the SSIDs and channel’s neighbouring wireless networks are using.

10) Check that all the correct drivers have been installed.

11) Check the config settings for encryption keys.

If you are still struggling then it can be a good idea to contact the manufacturer of your wireless router or a network supervisor.
