DSL or Cable Modem Not Working?

If you're getting errors loading web pages, and have already tried restarting your computer, modem, and wireless router, it might be an issue with your internet provider's DNS servers.

For our less tech savvy readers, DNS servers basically translate a domain name like "example.com" to an IP address like "208.77.188.166", which your computer can then use to contact the example.com web server.

You can switch your PC or router to use OpenDNS, for example. (There are instructions on the site for configuring different operating systems or many types of routers.)

I've recently been experiencing what I thought were outages, but it turned out to be flaky DNS servers. I've seen people on Time Warner / Road Runner, Comcast, and Cox complaining about this issue, but had never experienced it personally until the past few weeks. OpenDNS solved the problem, and has been working flawlessly so far.

Another good resource to consult, if you have another means of getting on the web, is the Broadband Reports forums section. There are sections for individual providers and regions, which makes it easy to see if others in your area are having issues, and what, if anything, they did to solve them.
