Six Wi-Fi problems and how to fix them

Jeff Bertolucci, PCWorld | May 23, 2011
Does your wireless network seem slow? Here are six common causes to wireless network interference, and what you can do to fix them.


Old firmware

Why upgrade your router’s firmware? Well, for performance improvements and occasionally a new feature or two. “Whenever you have a problem, check to see if you have good firmware. Sometimes there are little bugs out there, and the router manufacturer may already have a fix,” says Kalle. When you buy a new router, it’s always a good idea to check for the latest firmware as well.

The solution: Keep your firmware up-to-date. With older devices, you’ll have to access the router’s administrative interface (typically through a Web browser) to check for updates. The process is getting easier, though. “[Belkin] routers have an application—it’s almost like iTunes—that tells you whenever there’s new firmware available,” says Kalle. “The user can update by just pushing a button.”

Although the workings of your router may seem mysterious, following these simple tips can go a long way toward keeping your home wireless network in working order.
