9. TROUBLE SHOOTING
Countless hours of testing have given us a good sense of the most common challenges you will
encounter as an end user. If you have not already read 7. DEVICES and DRIVERS we STRONGLY
encourage you to do so prior to reading this section.
9.1 INTERNET CONNECTIVITY
We know there are few things more frustrating than being able to connect to the internet when you
want to. We found the follow addressed the issues we faced when testing the OPC.
9.1.1 I CAN’T ACCESS THE INTERNET
Right click on the network icon on the windows Taskbar and click on ‘Troubleshoot problems’.
Follow the steps and Windows will do it’s best to help you resolve the connection issue.

date when your OPC was setup and working fine. System Restore can be undone by running the
program again.

9.2.2 I CAN’T GET A WIRELESS SIGNAL
