Networking can be a tremendous pain, and almost every home that sets up a wireless Internet connection will occasionally have problems with it, ranging from the slightly annoying to the downright frustrating. To fix Internet problems with a wireless connection, computer users rarely have to do more than reset a few devices, but it’s important to know how to do this to avoid time consuming Internet issues.Resetting a modem is often the first step to fixing an Internet problem. Whether you need to fix an Internet connection that comes from a cable company, a satellite company, or a telephone company, they’ll usually tell you to turn off the modem, along with your wireless router. What many customer service gurus leave out is that both the modem and the wireless router need to be powered off for about two minutes. Once both have been unplugged, plug the modem in first, then wait a few minutes. Plug in the wireless router. This simple process will fix most Internet problems, as it resolves IP conflicts and other issues that plague home and office networks. Some wireless routers and modems also have a reset button that often needs to be pushed with a paperclip. This can be another way to accomplish a reset, but be aware that you’ll need to go through the router’s settings menu in order to fully fix Internet problems if you hit the reset. This is because the reset button often fully resets the router’s memory.Always keep the instruction manual for your wireless router nearby to help you fix Internet problems, and if you’ve already lost it, search for another manual on the Internet and print it out. Remember, if your wireless router is having Internet problems, you’re not going to be able to cruise the net to find a manual, so keeping a copy in an easily accessible place is always a good idea.With all router problems, the best tip is to be patient. In order to fix Internet issues, you may have to call your Internet company and the router manufacturer, but a bit of patience will help you fix the Internet quickly and knowledgeably.
