Wireless routers allow flexibility and freedom for many internet users. With Wi-Fi, one person can sit in a cafe and start surfing the web as if they were connected to a phone jack or cable at home. Even today, some people go completely wireless so that anyone nearby can access the network for free.

But with all the advantages of wireless routers that there are things you should keep in mind when we decided to connect the router. Wireless routers are not necessarily without its flaws. Here are some things to consider.

If a person is directly connected to the Internet with a cable and compare it with the same direction but with a wireless router, there would be a noticeable difference. The wireless connection will be slightly slower than the direct connection. The reason is simple: a Wi-Fi transmits in the air and there is some degradation of the medium. It’s like comparing between receiving antennas and cable television. Cable is obviously faster.

Possibly a major concern with wireless routers and Wi-Fi is in the encryption protocols. In some public Wi-Fi (as a local coffee shop), the transfer is free encryption. This means that all private data stored on your laptop or PDA will be exposed to anyone in the same area. It is possible that an unscrupulous person could obtain passwords and important personal information.

An older protocol wireless routers is the Wired Equivalent Privacy (WEP). Despite having a level of encryption, encryption can be easily compromised. The problem has caused a number of wireless router owners to update the protocols for WPA and WPA2 encryption.

With increasing Wi-Fi in the neighborhood, Wi-Fi pollution is increasingly evident. Sometimes, stores or broadcasting organizations in the same channel, causing interference and lack of access points. Cities are hardly aware of this problem as more users are jumping into the wireless world.

Other devices and equipment can also contribute to pollution. Studies have shown that Bluetooth devices, cordless phones and microwave ovens, all contributing to the interference of public wireless transmissions. This is a known problem in high density areas like cities with many access points.

Wireless routers do not have a limitless range. As such, the radio broadcasting could be limited to only one via 150 to 300 If you want to improve the range, you’d have to buy Wi-Fi antennas.

The Wi-Fi realm is different from other media such as Bluetooth. The energy consumption is much greater for devices using Wi-Fi through a router or access point. People who use PDAs or laptops will burn through battery power.

Another problem is that for countries around the world, you will find different spectrum allocations. The lack of consistency has caused problems for Internet users traveling from one country to another. In some cases, governments may prohibit the use of certain channels or require special authorization.

There are many disadvantages of wireless routers and Wi-Fi, but the disadvantages should not necessarily stop a person to use the service. Consider the pros and cons of the wireless realm before jumping to the World Wide Web.
