WLAN - uas yog thiab yuav ua li cas siv lawv? Yuav ua li cas mus cuag thiab siv WLAN configuration?

Niaj hnub no, cov neeg no ntau thiab ntau ntau muaj yog ib tug yuav tsum tau nce mus cov kev pab ntawm lub ntiaj teb no los yog cov neeg network los ntawm tej qhov chaw nyob rau hauv lub nroog daim ntawv qhia, lub teb chaws, lub ntiaj teb no. Muaj lub tsam thawj rau xis ua hauj lwm thiab kev lom zem, ntaub ntawv nrhiav uas siv ib lub computer, ib tug laptop, ib tug mobile xov tooj thaum koj nyob sab nraum koj chaw ua hauj lwm los yog lub tsev wireless technology tso cai. Rau hnub tim, lub npe nrov tshaj nyob rau hauv lub ntiaj teb no ntawm cheeb tsam network siv ib tug technology yog WLAN. Yuav ua li cas yog nws, yuav ua li cas ua tau thiab yuav ua li cas nws txuas no network? Cov lus teb rau cov lus nug no, koj yuav kawm tau los ntawm kev nyeem tsab xov xwm hais hauv qab no.

Lub tswvyim ntawm ib tug wireless network

WLAN stands rau cov Wireless lub zos Cheeb Tsam lub Network, uas txhais rau hauv Lavxias teb sab txhais tau tias "wireless LAN". Nyob rau hauv lub chav kawm ntawm lawv kev ua hauj lwm los tsim kom muaj kev sib txuas lus thiab cov ntaub ntawv kis tau tus mob nws tsis tau siv ib lub cable network (raws li nyob rau hauv cov ntaub ntawv ntawm ib tug pa wired kev twb kev txuas), thiab mloog xov tooj cua zaus. Qhov no ua rau nws ywj siab ntawm kev chaw thiab muaj ib tug loj tus naj npawb ntawm cov neeg siv. Cov feem nrov ntawm lub caij cov technology ntawm cov ntaub ntawv kis tau tus mob lawm cov airwaves yog Wi-nkaus.

Kev sib txuas lus ntawm WLAN thiab Wi-nkaus

Wi-Fi - nws yog tsiaj, lub resulting yuav txo tau lub sij hawm Wireless Fidelity, los yog "wireless ntseeg." Los ntawm kev siv ntawm no technology, cov neeg siv tau cov ntawv rau lub network nyob rau hauv tag nrho ib ncig ntawm nws kev pab them nqi. Feem ntau cov laptops muaj Wi-Fi cim - nws txhais tau hais tias lawv yuav tau tshaj WLAN tes hauj lwm.

Yuav ua li cas yog lub cheeb tsam kev pab them nqi ntawm ib tug wireless network thiab nws yog nyob ntawm? Qhov no yog tsis muaj lwm yam tshaj li cov kev pab them nqi rau thaj tsam Wi-nkaus, tsis pub dhau uas cov neeg siv yuav txav tsis rhuav kev twb kev txuas. Feem ntau, qhov kev ncua deb tshaj uas Pib ntsais koj teeb yuav kis tau yog hais txog 100 meters. Nws yog nyob ntawm ntau yam, nyob rau hauv particular - nyob rau hauv lub xov tooj ntawm obstacles thiab lawv hom. Nyob rau hauv txhua rooj plaub, WLAN yog ib tug ntau txhim khu kev qha txoj kev twb kev txuas tshaj cable tes hauj lwm. Tus nab npawb ntawm cov neeg siv yog suab xwb, thiab muaj peev xwm cuag lub ntau yam ntawm kev txiav txim los tsim kom muaj overlapping (yeem) nkag ntsiab lus thiab nce tus naj npawb ntawm cov neeg siv nyob rau hauv tib cheeb tsam.

WLAN xov tooj

Mus saib tau virtual network yuav tsum tau tsis tsuas yog los ntawm koj lub computer / laptop, tab sis kuj mobile. Yuav ua li cas yog ib tug WLAN nyob rau hauv koj lub xov tooj thiab yuav ua li cas yuav siv nws? Nyob rau hauv essence, qhov no yog ib tug dog dig wireless internet, tab sis tsis yog ib tug laptop PC, thiab nyob rau hauv koj lub xov tooj txawb. Qhov no muaj nuj nqi yog tam sim no kev mus rau hauv tag nrho cov tam sim no cov qauv thiab yuav ua tau heev yooj yim. Piv txwv li, Wi-nkaus, yuav tau zaum nyob rau hauv ib tug Cafe los yog tos rau koj ya davhlau ntawm lub tshav dav hlau - nyob rau hauv Feem ntau, nyob rau hauv tej pej xeem qhov chaw, qhov chaw uas muaj tsim nyog kev pab them nqi. Nyob rau hauv cov ntaub ntawv no, siv cov kev pab no yog feem ntau yog dawb xwb thiab tsis yog nyob rau hauv lub xub ntiag / tsis muaj ib tug SIM card. Lub tsuas tsis zoo - sai sai tso roj teeb. Connect Wi-nkaus (WLAN) yuav ua tau nyob rau hauv lub xov tooj nqis "Wireless tes hauj lwm", yog hais tias koj tsis pub dhau ntau yam ntawm ib tug lub qhov rooj.

zoo ntawm WLAN

Local wireless tes hauj lwm yog siv raws li ib tug extension los yog lwm txoj rau cable tes hauj lwm. Lawv installation yog kiag li tsis txhaum thiab, Ntxiv, nws yog pom zoo kom hais tias thaum muaj kev cable yog kev lag kev luam inexpedient thiab phim. Ib tug WLAN tso cai rau koj kom txuag tau nyiaj thiab lub sij hawm yuav tsum tau rau xov. Yog li, peb yuav highlight nws cov ntsiab zoo:

• muab siv tau rau ib tug network thiab hauv Internet, tsis hais txog ntawm tus neeg siv qhov chaw (txoj kev ywj pheej ntawm kev tshem + txoj kev ywj pheej yuav tau txais ntaub ntawv);
• yooj yim thiab ceev ceev siv ceev;
• uas tsis muaj nqi ntawm qhov kev siv;
• muaj peev xwm mus tau yooj yim nthuav lub network;
• compatibility nrog ntau hom / cov qauv ntawm cov pab kiag li lawm.

Qhov zoo ntawm ib tug wireless network yuav tsis tau overestimated (seb nws yog siv nyob rau hauv tsev los yog sab nraum nws), tab sis vim hais tias cov WLAN chaw nyob rau hauv lub chav tsev / tsev - lub tshuaj zoo meej rau xis ua hauj lwm nyob rau hauv lub Internet, tshwj xeeb tshaj yog yog hais nkag yog yuav tsum tau mus rau ob peb tsev neeg. Tom ntej no yuav tsum muab los ntawm nws cov kev twb kev txuas kev tswj.

Txuas thiab teem tau ib WLAN

Yuav ua li cas yog ib lub tsev wireless network thiab dab tsi hais tias nws yog ua? Nws yuav muaj xws li ib tug modem / router (lub qhov) thiab ib los yog ntau computers (cov neeg). Nws yog assumed tias koj twb muaj ib tug modem los yog router, hauv Internet thiab ua qhov tsim nyog WLAN-tsav tsheb (yog tias yuav tsum tau, nws yuav muab tau yooj yim downloaded rau lub network rau tej wireless adapter qauv).

Thawj kauj ruam yog position cov router:

• nws yog ntshaw kom tsa nws siab dua li uas lub teeb liab yog zoo faib thoob plaws hauv lub tsev-tsev;
• tshem tawm cov nyiaj pab ntau tshaj kev ncua deb ntawm lub ntau yam khoom tseem siv lub 2.4GHz zaus (TV, microwave, thiab lwm yam)., thiaj li tsis cuam tshuam nrog cov kev twb kev txuas.

Walkthrough

Taug kev mus rau configure tus nkag point (ie ib router):

1. Mus rau tej browser thiab nyob rau hauv qhov chaw nyob bar nkag mus rau IP-qhov chaw nyob ntawm peb modem. Koj yuav nrhiav tau nws nyob rau hauv cov ntaub ntawv nrog cov khoom. Nias lub khawm Sau.
2. Peb raug caw mus nkag rau ib tug ID nkag mus thiab lo lus zais. Lawv muaj peev xwm kuj yuav pom nyob rau hauv cov ntaub ntawv. Lub neej ntawd yog feem ntau yog siv chav admin / 1234 (tab sis tej zaum yuav txawv).
3. Peb tau txais mus rau lub ntsiab zaub mov thiab nrhiav tau ib tug WLAN point. Yuav ua li cas mus cuag ib tug wireless network? On qhov tsis tooj Wireless Lan muab ib daim tshev mus qhib. Cov tom ntej no kab npe (SSID), sau lub npe ntawm koj network (los ntawm cov uas nws yuav tsum tau qhia rau hauv daim ntawv ntawm muaj tes hauj lwm). Tom ntej no, sau lub npe ntawm lub cheeb tsam, thiab nyob rau hauv lub Channel teb no yog teem Auto. Nyem "Thov".
4. Peb npaj mus rau lub encryption chaw (txawv txoj kev). Qhib lub Wireless chaw tab thiab xaiv WPA (los yog WPA2) - Qhov no kev ruaj ntseg raws tu qauv yog zoo dua lub outdated 802.1x. Tom ntej no, koj yuav tsum sau ib lo lus zais (nyob ntawm seb tus qauv ntawm lub router, nws yuav hu ua txawv - Pre-qhia Ntsiab / Security Ecryption, etc.). Nws yuav tsum muaj tsis tsawg tshaj li 15-22 cim. Nyem "Txais".
5. Tam sim no koj yuav tsum mus sau npe rau lub npe ntawm cov pab kiag li lawm uas koj yuav muaj kev nkag tau mus rau koj lub wireless network. Koj xaiv los ntawm ib daim ntawv teev kev cob cog rua cov khoom nyob rau hauv lub teeb Access Sau (Advanced / Wireless chaw ntawv qhia zaub mov).
6. Qhov kawg kov: nyob rau hauv pem hauv ntej ntawm lub khoom Tig Access Control Nyob rau muab tso rau ib tug zuam. Npaj koj kev ruaj ntseg WLAN network.
7. Yuav ua li cas yog ib tug VPN? Qhov no virtual private network ntawm ib lub qhov (router) thiab lub computer, uas yog pom zoo kom siv tau rau kev ruaj ntseg cov ntaub ntawv kis tau tus mob nyob rau hauv lub network. Rau lub hom phiaj no muaj Hotspot ntaub thaiv npog kev pab cuam.
8. Yuav kom configure tag nrho cov neeg computers siv lub network teeb wizard thiab teem tag nrho cov tsis uas yog siv los ntawm lub qhov rooj.

Los ntawm cov nram qab no cov saum toj no cov lus qhia, koj yuav tsum tau teem ib lub wireless WLAN network uas muaj kev tiv thaiv los ntawm ib tug txhim khu kev qha encryption algorithm. Tam sim no koj lub tsev yuav muaj nws tus kheej kev pab them nqi rau thaj tsam ntawm Wi-Fi - thiab siv cov Internet yuav ua txawm ntau yooj yim thiab yooj yim.
