This is a common malady for computer users. Everything is working, but you can’t connect to the internet. Windows users might see a message about Limited Connectivity.
There are many possible causes, but I’ll cover some of the most common culprits. First, make sure the problem is actually with your wireless connection. Test the connection with another computer to verify that the connection actually works and the problem is with your computer itself.
* Reboot/Restart your modem and router. Basically, unplug them and let them rest for a minute. Then, plug in your modem first and then your router. Reboot your computer and test the connection.
* Disable software that may be causing a conflict. This may include antivirus software, firewalls, or any new software you installed recently. If you still do not have a connection, then at least software has been ruled out.
* Scan for infections such as viruses, trojans, and othe malware. Some of these can prevent internet connections and it’s a good idea to scan regularly anyway.
* Consider upgrading your router’s firmware. Instructions can be found at the manufacturer’s website.
Also, remember that almost every computer has an ethernet port which can be used to connect to your router via ethernet cable (Cat5). This is useful to test if the problem is indeed only wireless and allows you internet access so you can download files and research your problem.
