If you have a laptop or tablet connected to the Internet using WiFi (wireless) You have probably noticed that the speed of the Internet is not consistent and sometimes extremely slow. The wireless connections depend on many factors and is not always easy to find what the problem is. But here are the most common problems that occur with WiFi connections and how to fix them.

1. The Internet speed is less than that promised by the provider: most ISPs (Comcast, Verizon, Cox) offer tiered Internet service: the faster the Internet, more pay. But not always the actual speed you get is the promised and it turns out you are paying for something you are not getting. How to know the actual speed? connect your laptop (or computer) directly to the modem or router using a network cable and make sure no one else in the house is using the Internet. Using your favorite browser, go to www.speedtest.net and click “Begin Test”. Record the results for “Download Speed” and “Upload Speed” (eg 5.4Mbps and 15.4Mbps). Look in your contract which is the promised speed and if your provider is much lower, give them a call to be checked for the connection.

2. The wireless signal is very weak in some parts of the house: The wireless signal has a limited range and as we move away from the router the signal becomes weaker, and the Internet becomes slower and off periodically. One solution is to move the router to another location, but most of the time you have to run cables and is very expensive. My favorite solution is to use a kit ($ 50 at Amazon) that extends the WiFi signal using the grid of the house. It is very easy to install and configure. Basically it connects one near the router and the other in the place you want to improve the signal, the name of the WiFi network is configured and ready.

3. There are many WiFi networks around it is difficult to find a home that does not have a WiFi router these days. And the problem here is that the WiFi routers use the same radio frequency (2.4GHz), sometimes leading to saturated. This is especially common in apartment complexes where there are dozens of WiFi connections. The WiFi routers today are (or should be) smart enough to switch to different “bands” within the 2.4GHz frequency, but this does not always happen. Here the solution is to upgrade to a newer router ($ 40 at Amazon) that supports 5 GHz frequency, which is much less used and faster.
