Yog li nws yog ib txwm qhia koj yuav tsum tsis txhob nkag mus rau koj cov ntaub ntawv rhiab zoo li cov ntaub ntawv hauv tuam txhab nyiaj, kev them nyiaj online thiab lwm yam siv pej xeem qhib WiFi.
Thaum nkag mus rau qee qhov chaw, ib qho teeb meem tshwm sim txog cov ntsiab lus ntawd lossis qhov chaw raug thaiv, thiab koj nkag tsis tau. Nws tuaj yeem yog vim kev kawm lossis kev nom kev tswv lossis lwm yam laj thawj. Piv txwv li, Cov Tsev Kawm Qib Siab muab txhua tus tub ntxhais kawm ntawv nkag mus rau daim ntawv pov thawj kom lawv nkag tau mus rau tsev kawm qib siab WiFi. Tab sis qee qhov chaw (xws li torrent thiab lwm yam), uas cov tsev kawm qib siab pom tsis haum rau cov tub ntxhais kawm, tau thaiv lawv kom cov tub ntxhais kawm nkag tsis tau rau lawv siv tsev kawm qib siab WiFi.
Yog li, txhawm rau daws tag nrho cov teeb meem no, VPN los rau hauv lub luag haujlwm.
