Kev piav qhia ntawm wifi wireless network card

Ua raws li IEEE 802. Wireless wifi network card 11n (Draft 2.0), IEEE 802.11g, IEEE 802.11b qauv. Ua-hauv lub kav hlau txais xov ntse muab kev ua haujlwm zoo dua ntawm kev sib kis, kev ruaj ntseg thiab kev pabcuam wireless. Nyob rau tib lub sijhawm, CCA thev naus laus zis tau txais yuav, uas tuaj yeem zam kev cuam tshuam cov channel thiab ua kom tag nrho cov txiaj ntsig ntawm kev sib txuas channel. Cov khoom no txhawb nqa 64/128/152-ntsis WEP encryption, nrog rau kev encryption siab heev thiab kev ruaj ntseg mechanisms xws li WPA/WPA2, WPA-PSK/WPA2-PSK, thiab lwm yam. Nws kuj muaj QSS ceev Kev ruaj ntseg teeb tsa muaj nuj nqi, ua raws li WPS, thiab tuaj yeem teeb tsa kev ruaj ntseg wireless yooj yim. Tsis tas li ntawd, cov khoom lag luam muaj kev pabcuam tseem ceeb los xyuas kom meej qhov tseem ceeb ntawm cov ntaub ntawv bandwidth-rhiab heev xws li video thiab lub suab. Cov khoom no kuj zoo sib xws nrog 11g cov khoom thiab lwm yam khoom 11n.
