How Do I Prevent Slow Internet Service?

Jeremy Laukkonen

In order to prevent slow Internet service, it is important to make sure that everything on your end is functioning properly, and that you avoid using the network in ways that are not approved of by your Internet service provider (ISP). There are a number of different factors that can cause slow Internet service, from viruses and malware on your computer, to artificial limits imposed by your ISP. The first factor you should typically investigate is the hardware you use to connect to the Internet, which may include a modem, router, and other equipment. If your hardware is up to date and working properly, then you may want to scan your computer for viruses, malware, rootkits, and other malicious software. In some cases, you may also find that your ISP has limited your transfer speeds for reasons such as excessive usage.

One of the major factors that can lead to slow Internet speeds is your hardware. If you notice that your download speeds have degraded severely, and all the computers connected to your network are experiencing the same problem, you should inspect your modem or router. In many cases, it is possible to reboot this type of equipment by turning it off and then back on, or by unplugging it for a few minutes. It is also possible for certain types of computer malware to alter router and modem settings, so you may want to check into that as well. Moreover, if the router is a few years old, upgrading to a newer, faster model could provide an increase in speed for the wireless devices in your home. Issues with wireless cards can also cause slow Internet service, as can obstructions between a laptop and a wireless router.

If only one computer on your network is suffering from slow Internet service, it is typically a good idea to check it for viruses. Virus scanners can find most of these malicious programs, though you may also want to use scanners that check specifically for adware, malware and other invasive programs. In some cases, you may need to download specialty software to deal with difficult issues such as rootkits. It is also important to be sure that your network is password protected; if it is not, then people who live near by may actually be stealing some of your bandwidth. If there are no issues with your hardware or software, then the root cause of the slow Internet service is probably somewhere in the network.

Certain types of traffic on your home network, and artificial limitations imposed by your ISP, can also have an adverse affect on Internet speeds. If your Internet service suddenly becomes very slow, you should make sure that there are no file sharing programs running on your network. These programs can sometimes adversely affect transfer speeds, especially if there are a great deal of incoming and outgoing connections. In some cases, Internet service providers will also impose artificial limitations, called "throttling," to your download or upload speeds. It is important to stay within any data transfer limits that your ISP has imposed if you want to avoid this cause of slow Internet service.

And if you want to find out what channels are currently in use in your area, there are open source programs you can download that will report just that. Simply search for one, download it, run it and see which channels are the least used.

With that information, configure your wireless router's setting so that it communicates on another channel. That's a fairly simple way to deal with interference problems.

What is surprising is how often wireless routers need to be rebooted. Whenever there is an Internet or network speed problem, the culprit is typically the wireless router. Reboot that and things will usually turn out fine.

Another problem may be that the wireless router is using a channel that is being used by other ones in the area and is causing interference. To see if there are a lot of wireless routers in your area, simply open up the list of available connections that your computer can "grab" and connect to (the method of choosing a router and connecting to it varies from operating system to operating system) and see what you find. If you have a lot of options, there's a good chance the channel on which your router is communicating is conflicting with another router.
