Skills of enhancing wifi signal

1, using the latest Wi-Fi technology. One way to ensure a smooth high-speed network is to use the latest firmware. You should know that in WLAN protocol, the speed of 802. 1 1n is obviously higher than that of 802.1a, 802.1b and 802.1/kloc. However, it must be noted that if you want to improve the speed, you must be equipped with an 802.6438+0 1N network card and a wireless router.

2. Place the router in the best position. The router is ugly, but don't always hide behind the TV cabinet. If you want the strongest signal, you'd better put it in an open space without walls or obstacles. The antenna should be straight and as high as possible (some readers find that the router has the best signal after being placed in the attic).
