How to fix and troubleshoot Internet connection problems?

If your Internet is down or there is an intermittent connection issue, there could be several reasons for it. It is important to troubleshoot and pinpoint the underlying problems. If you have trouble connecting to the Internet, the likely cause of that may be that your Internet service provider is down. Even large companies like Comcast can sometimes experience problems with their servers, cable or connection. But before blaming your service provider and calling them which involves waiting on the phone, there are some other things you can do.

If you are on Windows PC like Windows XP, Windows 7 or Windows 8, you can open the console or terminal to help troubleshoot your Internet connection problems. This can generally be found by opening up the start menu and searching for “command prompt”. To find out if you have a connection to the Internet, trying typing “ping 8.8.8.8″. If you see a few lines coming back that looks like “Reply from 8.8.8.8: bytes=32  time =433ms”, then you should not have any issue reaching the Internet. If you do not see any reply coming back, chances are that your Internet connection is down. If you have problems reaching a website, it is possible that you have problems reaching your DNS server or your service provider’s DNS may be down which can be quite common. On the command prompt again, try doing a DNS lookup to see if you can reach the DNS server. Type in ” nslookup www.google.com” to see if you can get an IP address back. If you cannot, then either the DNS server is down or there may be a problem with reaching the DNS service.

In any case, one thing you can try is rebooting your machine and starting up your browser to see if it works. If it still does not, the next likely culprit may be your router. Make sure that you are connected to the Wifi correctly and it is not because you have lost your Wifi connection. The best way to see if your router is down or not is to connect a cable directly from the router to the PC. If you are connected directly and still cannot connect, then it may be time to reboot both the modem and router. You may also need to configure your router correctly either by logging into it on www.routerlogin.net for routers such as Netgear or other IP address for other type of routers.  To reboot your router, pull the plug off from your router and then from your modem and wait 10 seconds. Then reconnect the power to your service provider modem followed by power back to your router. Wait a little bit for the connection to establish. By resetting your router this way, it mostly solve 80% of Internet connection problems.

If rebooting your PC, rebooting your modem and router still does not work and you are pretty sure that it is not a router configuration issue or a bad cable, then it is time to call your service provider. A service provider like Comcast are sometimes able to detect the area you are in based on your phone number and even automatically let you know that they are aware of Internet connection problems in your area. In some cases, you can even leave a callback number to be notified when the service will be up again. There are cases when there is a DNS issue and in those cases, you just need to wait for the DNS service to be restore.
