Cope with Computer Glitches

Computers, too, suffer from technical glitches. Although relatively uncommon nowadays, a computer's network adapter hardware might suddenly fail due to overheating or age. Failures in the operating system software that control the adapter, on the other hand, can occur frequently especially with computers that are heavily used. Viruses and worms also may disable or block a computer's network interfaces from functioning properly. Finally, if using a laptop or other mobile device, transporting it from one location to another can corrupt the state of its network.

Action - Check the computer for malware and remove any found. On Windows computers, try resetting the network connection. Reboot the computer if necessary.
