Why does your Internet connection drop when you need it the most? Why does Netflix keep on buffering? Why do you experience lag when playing online games? Slow or intermittent Internet connection is such an inconvenience.  Today, we will discuss some common tips to keep your network optimized and up to speed. I divided this discussion into three different parts, wherein we will discuss each part and explain how it can help speed up the Internet connection.

Wireless Interference

Nowadays, most of our devices use wireless connection and it is very important that we have a basic idea on how wireless connection works and how we can avoid wireless connectivity issues. Wireless interference can be broken into two categories; the physical interference and the electromagnetic or signal interference. The first kind of interference is the most easily understood, this is the physical interference from walls, floors, ceiling, and other permanent fixtures in the vicinity. Identifying the best spot where to put the router is your main objective here. Your wireless router transmits a spherical signal so it would be better to put your router in the center of the house. With antenna, height is might so it’s better to have the router on the ceiling than on the floor. Avoid putting your router/access point directly adjacent to any kind of obstruction or wall. Most walls block signals, to some degrees. If you can identify the best spot for your router, then you need not to worry about physical interference.

Signal interference is basically the noise created by other devices running on the same frequency of your router. This noise or interference can affect your wireless connection a lot and might even disconnect you from the Internet. First, you have to identify which frequency your router is transmitting at. Some router transmits at 2.4 GHz, some are at 5 GHz, and others are dual band which basically transmit on both 2.4 GHz and 5 GHz. Second, identify the other devices at home that can cause signal interference. In theory, anything running on electricity can emit interference in the form of a magnetic field; other competing radio waves; or both. When two waves of the same frequency but from different sources collide, they can cancel each other out or interfere with each other. Also, since different waves of the same frequency all have the same characteristics, the devices will still connect to your network but the other signal will interfere causing your Internet to drop. So, if your Wi-Fi-capable laptop is sitting near your microwave oven, and the oven is on, your computer will then receive signal from both the microwave and the wireless router! Bluetooth devices, microwave ovens, and some wireless phones, baby monitors and walkie-talkie operates in the 2.4 GHz range. Any of these devices can interfere with your wireless connection. Do your homework and check your devices, their frequencies, and their location. Make sure that you position everything where you will get the least interference.

PC Optimization

Adware, Trojan, Malware, and Viruses — they all send data to the Internet and can create network traffic. Just one dirty computer on the network can create network traffic and can ruin your whole Internet connection. Make sure that you have all your computers optimized regularly. I strongly suggest a cleanup on all computers every three months.  This will also include cleaning your temporary Internet and system files, registry, junk programs, and junk files. Running PC optimization regularly can also prolong computer life, just like tuning up your car regularly.

Automatic Update

This is my personal opinion — if it’s not broken, don’t fix it. If the program is perfectly running, then you do not need to update it. Most of the programs that you install in your computer has update checker running on your computer’s background. This checker sends and requests for data on the Internet to keep the program up to date. If you have multiple programs running with update checker running on the background, then you are creating traffic on your network. This will also consume download and upload speed. It would be best to turn off this updater from running upon start up. You can turn them off thru the Startup and Services tab by running the “msconfig” command.

Knowing this basic information, doing your homework and regular cleanup of your computers can give you a worry free Internet connection. This will also give you a fast and reliable Internet connection. I hope that this has been informative and you enjoyed reading it. Thank you and have a worry free Internet connection.
