Unable to access Internet resources and want to know what to do now?  Following are the top five steps to get your small business back online now.

unable to access internet

  1. Call your Internet Service Provider (ISP).  The first step is to rule out any area-wide problems with your ISP.  If all is well, proceed to step two to check your infrastructure.
  2. Reboot your network bridge.  Find your cable/DSL modem or T-1 router and power it down.  Wait five minutes and turn it back on.  Test your Internet connection and if you still do not have access, proceed to the next step.
  3. Ping your router.  Try to ping your router's IP address.  If you do not know it, do the following:
  • Go to Start->Run, type "CMD" and press "OK"
  • When the black command window appears, type "IPCONFIG" and Enter
  • You will see an IP address for the default gateway (e.g. 192.168.1.x)
  • Type "Ping" followed by the IP address you found above and see if it replies
  • If your router does not reply try rebooting your switches
  • Ping an outside IP address.  If you are able to ping your router, try pinging an outside IP address.  A good one to try is 4.2.2.2 which is Comcast.  If this gives you a reply, you will then try by name.  Try to ping www.google.com
  • Reboot your Domain Name System (DNS) server.  If you were unable to ping www.google.com, you most likely have a DNS issue.  Try to reboot your DNS server which is most likely your domain controller.

If you need help with any of this, please feel free to contact our small business IT managed services.
