Fascinating subject, that of wireless networking. Like other subjects related to computers and technology, it has evolved fast.

What is the most common problem when it comes to wireless connections? The signal is too weak. In other words, the connection drops, or its speed is considerable slow, the quality of the connection is poor, and so on. So, what do you do?

The first and most fundamental concept you need to grasp on the subject is LINE-OF-SIGHT. In its simplest form, it means literally that, i.e. if your wireless receiver (in your computer) can SEE the transmitter (usually a router connected to the internet cable that comes into your place), you’re in good shape. Radio signals used by wireless networking connections are similar to normal light. Normal light doesn’t get through a wall. Well neither does the wireless signal. Well maybe not exactly the same. Wireless signals are slightly better at that than normal light. But you get the idea. Using that concept, you know that if your transmitter is in the living room and you are in your room, with a wall in between, the quality of the wireless connection is going to suffer. Or if you are one floor above the transmitter, again an obstacle prevents line-of-sight, this time the floor.  Add enough physical obstacles and distance, and your connection is no longer able to be sustained.

Therefore, if at all possible, maintain line-of-sight between your computer’s wireless receiver and the transmitter. If you can’t, for whatever reason, then there are several things that can be done. One is, adding a better suited antenna to the receiver, or the transmitter. Another one is increasing the power of the signal being transmitted. A third one is adding a repeater. This is perhaps my favorite one. The idea is to add an additional device between the transmitter and the receiver. Its function is to receive the signal coming from the transmitter, and re-transmit it, with new strength and proximity to the receiver. So instead of:

Transmitter ———————————> Receiver

We have:

Transmitter ———Repeater————-> Receiver

The benefits are obvious, and the results invariable.

Let me know if you are having trouble on this area. I can help you improve the quality of your wireless signal.
