There are several types of encryption algorithms:
The last three varieties are most often used to encrypt the channels with the data transmitted on Wi-Fi technology.
Technology WEPбыла established relatively long ago, it is one of the most unreliable. To connect to a secure channel it is easy even for less experienced users who do not know the password.
The principle of operation of this encryption is similar to the following.
In 2004 we created a new encryption scheme that is still being used – WPA/WPA2 (WPA2 — modified). As it is extremely reliable.
Modes b/g/n and channels the wireless network
There are several modes in which the work Wi-Fi network. Each one has a different transmission speed and coverage.
Letter symbols are the following:
n – the fastest mode (highest available speed – 600 MB/s);
g – medium-speed mode (the maximum speed is 54 Mbit/s);
b – the slowest mode (the available transmission rate is only 11 Mbps).
Often, for normalization of work simply toggle the Wi-Fi router. As some devices don’t support n mode, where it is possible to work Your router. For example – iPhone 3GSподдерживает work with Wi-Fi-router mode only b and g. Thus, the inability to connect to the router may be incompatible modes of operation.
