Qhov tseeb WiFi tej chaw - tus yuam sij rau wireless kev ruaj ntseg

Wireless technologies, uas yog heev nquag nkag tau rau hauv lub neej txhua hnub, tsa cov kev nplij siab thiab muaj ntawm ntau ub no txhua hnub mus rau ib tug tshiab. Nyob rau hauv qhov tseeb, feem ntau cov neeg tsis tau xav txog tej yam lawv lub neej tsis muaj ib tug xov tooj txawb, mobile Internet tau ua yuav luag ntau dua wired, thiab ntau tsav tsheb ntseeg ib tug wireless mloog ntawm pob ntseg invention me ntsis tsawg tshaj li ib qho tseem ceeb cov invention ntawm lub tsheb.

Tab sis nyob rau hauv lub chav kawm ntawm kev kawm tsis yog tsis muaj ib tug diav ntawm ib. Qhov no stems los ntawm cov kev ruaj ntseg ntawm wireless tes hauj lwm. Muaj mob thaum lub tuam txhab vim hais tias ntawm kev ruaj ntseg vim li cas, sim kom txo tau txoj kev siv cov wireless network twg rau tib LAN, thaum tsim ib tug kev twb kev txuas mus rau lub internet rau tag nrho cov pab kiag li lawm rau hauv lub network los ntawm ib tug hlau yog kim thiab nyuab.

Ib qho ntawm feem nto moo thiab nrov network raws tu qauv yog WiFi. Ntau precisely, ib tug tag nrho tsev neeg ntawm kev cai nrog txawv kev txhawb, nrog rau cov kev twb kev txuas ceev thiab cov kev tiv thaiv txhais tau tias kev ruaj ntseg compound. Txawm li cas los, WiFi teeb tshwm sim nyob rau yuav luag tib lub tsis hais txog ntawm kev kho nqi lus ntawm tus txheej txheem, uas yog siv los ntawm koj lub ntaus ntawv.

WiFi chaw, feem ntau yog pib nrog rau cov chaw ntawm cov kev nkag point. Ua li no, ua ntej, mus cuag nws mus rau ib tug PC los yog laptop ntawm ib tug ib txwm UTP-cable. Nyob rau feem ntau lub qhov los yog cov ntaub ntawv nws yuav tsum tau teev tus ID nkag mus thiab lo lus zais los lub neej ntawd, thiab lub network chaw nyob uas tus neeg siv yuav saib tau lub firmware ntawm lub qhov rooj. Sau nyob rau hauv lub chaw nyob bar ntawm koj tus browser qhov chaw nyob hauv qab no - koj tus ID nkag mus thiab lo lus zais los ntawm cov khoom Chaw tsim tshuaj paus, thiab tau mus rau hauv lub WEB-interface ntawm lub qhov rooj.

Yog hais tias koj tsis delve rau hauv lub intricacies, WiFi chaw yog txo mus rau qhov kev txiav txim ntawm ib tug ob peb tsis. Ua ntej, koj yuav tau qhia kom meej rau cov IP nkag ntsiab lus nyob rau hauv koj network. Ntawm cov hoob kawm, raws li nrog rau tej lwm yam ntaus ntawv configuration, cov thawj peb octets yuav tsum yog tib nrog cov uas nyob hauv lwm network pab kiag li lawm. Ntxiv qhia txog cov network SSID (ua tau nws yog - ib tug network lub npe uas yuav tsum pom mus rau lwm cov neeg thaum kev cob cog rua). Ntxiv mus, ib co kev nkag ntsiab lus cia koj mus xaiv lub hom txuj uas yuav siv tau thaum txuas lwm yam pab kiag li lawm.

Ib qho tseem ceeb qhov chaw yog enabled los yog DHCP neeg rau zaub mov shutdown. Yog hais tias koj pab kom nws, ces tej dais uas yog kev cob cog rua rau koj network, koj yuav tau txais lub chaw yuav tsum tau siv no nkag point (IP, rooj vag chaw nyob, thiab ntawm DNS-servers). Nyob rau hauv cov ntaub ntawv no, nws yog ib co ntshaw kom teem nyob rau hauv tib lub ntau yam ntawm cov chaw nyob sau ua ke mus rau qhov tshiab kiag li lawm. Qhov no yuav tsum tsis txhob tau kev tsis sib haum nyob rau hauv lub network.

Cov theem tom ntej ntawm kev nkag tau taw tes tej chaw - Teem network kev ruaj ntseg. Nws yog heev undesirable, tsis muaj qhov zoo yog vim li cas rau tawm hauv lawv taw tes ntawm kev nkag tau tsis muaj ib lo lus zais thiab tsis muaj kev tiv thaiv. By xaiv ib lo lus zais yog tsim nyog los noj kev saib xyuas. Obviously, qhov ntau nyuaj nws yog, qhov ntau txhim khu kev qha yuav cov kev ruaj ntseg system wireless network. Nws yog zoo dua yog hais tias tus password yuav muaj xws li ob tus xov tooj thiab cov tsiaj ntawv, thiab ob loj thiab lowercase. Qhov ntev yog ntau dua los yog tsawg ruaj lo lus zais - yam tsawg kawg 10 cov cim. Nyob rau hauv tas li ntawd mus rau lub lo lus zais, wireless kev ruaj ntseg nyob rau hauv lub hom encryption. WiFi txheem yuav siv cov ob hom ntawm encryption - WEP thiab WPA. Tu siab, thaum lub sij hawm 2001-2007 lub sij hawm nws twb tau pom ob peb txoj kev nraaj thiab sai sai tawg lub WEP encryption algorithm, ua txuj no yog tsis tshua muaj tsis zoo. WPA yog ntau resistant rau ntes, thiab twb tsis tau tau npaj kev vam meej kev algorithm bypass no tiv thaiv, haum rau loj siv. Txij li thaum tag nrho cov pab kiag li lawm nrog WiFi logo yuav tsum txhawb nqa WPA2 encryption yam, uas ntxiv zog lub ntseeg ntawm wireless LANs txij thaum 2006. Yog li ntawd, yog tias koj cov khoom tau qhia tom qab no lub sij hawm, nws yuav ua rau kev txiav txim zoo rau siv ntau tshaj plaws niaj hnub thiab sustainable txoj kev uas yuav tiv thaiv wireless kev twb kev txuas.

Cov kauj ruam tom ntej - qhov chaw kawm lub WiFi adapter rau ib tug laptop los yog gadget. Ntawm no, txhua yam yog yooj yim npaum li. Los ntawm cov kev twb kev txuas ntawm ib tug tswv rau ib tug wireless network uas yog tam sim no nyob rau hauv lub qhov rais tsev neeg ntawm kev khiav hauj lwm systems ntawm version XP, koj yuav tsum nrhiav tau cov SSID network nrog rau txoj kev, nkag mus rau rau lo lus zais thiab qhia kom meej hom encryption, uas zoo sib xws rau cov neeg uas koj siv thaum configuring txoj kev mus taw tes. Yog hais tias ib tug DHCP neeg rau zaub mov rau cov kev nkag point twb tau muab tawm, nws tseem yuav tau manually nkag mus tsis xws ib tug network kev twb kev txuas, zoo li IP, GW thiab DNS-servers.
