I oluyilo Izilungiselelo ze-WiFi - isihluthulelo nokuvikeleka engenantambo

ubuchwepheshe Wireless, okuyinto kakhulu ngenkuthalo busuka ekuphileni kwansuku zonke, wavusa induduzo ukuhamba imisebenzi eminingi yansuku zonke kuya ezingeni entsha. Eqinisweni, abantu abaningi abakwazi ukucabanga ngokuphila kwabo ngaphandle umakhalekhukhwini, i-Internet mobile sekube ngasuthi ezivamile ezingaphezu kuka yezintambo, nabashayeli abaningi bakholelwa wireless earphone we okusungulile kancane ayibalulekile kunalokho kokusungulwa kwemoto.

Kodwa ngokuhamba entuthukweni yezobuchwepheshe kwaba hhayi ngaphandle spoon yomsizi netiyela. Lokhu kubangelwa ukuthi ukuphepha kwe-amanethiwekhi wireless. Kukhona amacala lapho inkampani ngenxa yezizathu zokuphepha, wazama ukunciphisa ukusetshenziswa engenantambo zenethiwekhi yezifiso ku-LAN efanayo, ngenkathi wakha uxhumano kwi-inthanethi kuwo wonke amadivayisi kunethiwekhi ngokusebenzisa wire ayebiza futhi eziyinkimbinkimbi.

Omunye edume kakhulu futhi ethandwa inethiwekhi olandelwayo kuyinto WiFi. Okuningi ngokunembile, wonke umkhaya yezifiso ngemininingwane ehlukile lobuchwepheshe, kuhlanganise speed uxhumano kuhlanganiswe izindlela zokuzivikela nokuvikeleka kwakwakhe. Nokho, Ukuhlelwa kwe-WiFi kwenzeka cishe ngendlela efanayo kungakhathaliseki ukuthi wokubuyekeza ethile standard, okuyinto esetshenziswa kudivayisi yakho.

Izilungiselelo ze-WiFi, ngokuvamile kuqala nge-izilungiselelo yokungena. Ukuze wenze lokhu, kuqala, ukuxhuma ku-PC noma laptop nge evamile UTP-ikhebula. On kakhulu yokufinyelela noma imibhalo-ke kumele icaciswe login nephasiwedi ngokuzenzakalela, futhi ikheli inethiwekhi lapho umsebenzisi angafinyelela firmware we yokungena. Ngena ku yekheli yesiphequluli sakho kuleli kheli elingezansi - login yakho nephasiwedi kusukela umkhiqizi womsebenzi, singene WEB-esibonakalayo yokungena.

Uma ungenalo lokumba butholakala enqubweni eyinkimbinkimbi, kulungiselelwa WiFi kuyehla kube ukunqunywa kwendlela imingcele embalwa. Okokuqala, kuzomele ucacise IP zokungena ngaphakathi kwenethiwekhi yakho. Yiqiniso, njengoba nanoma iyiphi enye ukumisa kudivayisi, octets yokuqala emithathu kufanele ifane nalabo namanye amadivayisi kunethiwekhi. Ngaphezu kwalokho icacisa SSID yenethiwekhi (empeleni kuba - igama inethiwekhi ezobonakala kwabanye abasebenzisi uma ixhunyiwe). Ngaphezu kwalokho, amanye amaphuzu ukufinyelela akuvumela ukuba ukhethe uhlobo ejwayelekile ezizosetshenziselwa lapho yokuxhuma namanye amadivayisi.

Kuvele kulungiselelwa ezibalulekile kuyasebenza noma DHCP-iseva ukuvala shaqa. Uma unika amandla, bese iyiphi idivayisi ixhunywe kunethiwekhi yakho, ngeke ngokuzenzakalelayo wamukele amasethingi adingekayo usebenzisa le yokufinyelela (IP, ikheli le-IP, kanye DNS-amaseva). Kulokhu, kuyatuseka kakhulu ukuze usethe uhla efanayo amakheli zabelwe amadivayisi amasha. Lokhu kuzokwenza kugwenywe izingxabano kungenzeka ngaphakathi inethiwekhi.

Esigabeni esilandelayo ukufinyelela izilungiselelo iphuzu - Setha nokuvikeleka inethiwekhi. It is engathandeki kakhulu, hhayi kokuba izizathu ezinhle ukushiya iphuzu labo lokufinyelela ngaphandle kwephasiwedi futhi ngaphandle ukuvikelwa. Ngokukhetha iphasiwedi kuyadingeka ukuze unakekele ethile. Ngokusobala, kunzima kakhulu njengoba linjalo, njengeliyiZwi kunokwethenjelwa kuyoba uhlelo nokuvikeleka inethiwekhi engenantambo. Kungcono uma iphasiwedi izobandakanya kokubili izinombolo kanye namagama, futhi womabili usonhlamvukazi kanye ezincane. Ubude iphasiwedi ngaphezulu noma okuncane - okungenani izinhlamvu ezingu-10. Ngaphezu iphasiwedi, ukuphepha engenantambo lincike ohlotsheni ukubethela. standard WiFi kuhilela ukusetshenziswa ezimbili izinhlobo ukubethela - WEP WPA. Ngeshwa, ngesikhathi 2001-2007 inkathi kuye kwasikiselwa izindlela eziningana ukuze kahle futhi ngokushesha crack algorithm WEP ukubethela, okwenza le ndinganiso ayiphephile kakhulu. WPA kuyinto ezikwazi ukumelana ngokuhlaziya, futhi ingakamiswa ezihlongozwayo yimuphi yimpumelelo algorithm dlula lokhu kuvikela, ezifanele ukusetshenziswa mass. Njengoba wonke amadivayisi nge logo WiFi kufanele sisekele WPA2 ukubethela uhlobo, elibuye anda ukuthembeka LANs engenantambo kusukela ngo-2006. Ngakho-ke, uma imishini yakho iye kwetfulwa ngemva kwalesi sikhathi, kunengqondo ukusebenzisa indlela yesimanje kakhulu futhi esimeme ukuvikela ukuxhumana okungenawaya.

Isinyathelo esilandelayo - ukusetha adaptha WiFi kukhompuyutha ephathekayo noma igajethi. Lapha, konke kulula kakhulu. Ngokusebenzisa uxhumano senkosi kunethiwekhi engenantambo elikhona umndeni Windows of yokusebenza izinhlelo kusuka version XP, kumele uthole i-SSID yenethiwekhi nge ilungelo, faka iphasiwedi kanye ucacise uhlobo ukubethela, ezifana nalezo oyisebenzise uma ulungiselela yokungena. Uma DHCP-iseva kwindawo yokungena kuvaliwe, le ntengo isazoba kudingeka ufake nemingcele ezifana ukuxhumana kwenethiwekhi, efana le-IP, GW ne-DNS-amaseva.
