On the other hand, set the configuration Wi-Fi router wireless, select another channel defined by default. This is to ensure that they are not the same as other sources in the channel close to the wireless network. If control of the router configuration to ensure that the maximum transmit power and signal type is set, wireless 802-11A, 802-802-11g or 11n, set as it offers the best selection needs .

If after applying all the advice, the signal strength is too low, please take a Wi-Fi amplifier, the signal is passed to extend the range. Alternatively, you can try using aluminum foil behind the antenna such as routers, which shows the wireless signal for laptops. This will certainly improve the signal, but you have to experience the curvature and orientation of the film to get the best results.

No matter how carefully the wireless router can reach very rarely more than 50% of its maximum speed. Wired LAN at 100 Mbps always worked, but 11 and a 802-11g-802, a theoretical top speed of 54 Mbps, but rarely more than 25 Mbps, 802-11n mode should work to last about 100 Mbps, but are subject to interference, such as two channels to each other. The electronics faster and more reliable Wi-Fi router with a LAN connection speed is now possible.

If you have a Wi-Fi instead of a LAN, then unfortunately you have to wait an Internet connection is slow, but sure, but will benefit from the convenience.
