Yuav ua li cas teem ib USB WiFi Adapter nrog tus txiv pos Pi

by Cai Richard Saville

Txuas mus rau hauv Internet Nrog Koj Cov Tub Ntxhais Hluas

Rau txhua txhua version of Raspberry Pi ua ntej Pi 3, txuas mus rau hauv internet tau ua tiav hauv ib ntawm ob txoj kev - txuas ntawm qhov chaw nres nkoj Ethernet los yog siv USB WiFi adapter.

Tsab ntawv xov xwm no yuav qhia koj txog teeb tsa ib lub USB WiFi adapter nrog koj Pi, siv lub Edimax EW-7811Un hauv qhov ua piv txwv no.

Connect Hardware

Tua koj tus txiv pos thiab kom haum koj lub WiFi adapter mus rau hauv Pi lub USB ports, Nws tsis muaj qhov chaw nres nkoj koj siv.

Tam sim no kuj yog lub sij hawm los txuas rau koj cov keyboard thiab screen yog tias koj tsis tau ua li ntawd.

Tig rau koj tus txiv pos thiab muab ib feeb rau khau raj.

Qhib Terminal

Yog hais tias koj Pi plab hlaub rau lub davhlau ya nyob twg los ntawm lub neej, hla qhov kauj ruam no.

Yog hais tias koj Pi plab hlaub mus rau Raspbian desktop (LXDE), nias lub davhlau ya nyob twg hauv cov haujlwm. Nws zoo li lub monitor nrog ib qho screen dub.

Kho cov ntaub ntawv Interfaces Network

Thawj hloov ua yog ntxiv ob peb kab rau cov ntaub ntawv network interfaces. Qhov no teev tau tus USB adapter siv, thiab tom qab ntawd peb yuav qhia nws txog qhov txuas mus rau.

Nyob rau hauv lub davhlau ya nyob twg, ntaus hauv cov lus txib nram qab no thiab nias sau:

sudo nano / etc / network / interfaces

Koj cov ntaub ntawv yuav muaj qee cov ntawv nyeem nyob rau hauv nws, uas tuaj yeem sib txawv nyob ntawm seb koj version of Raspbian. Txawm li cas los xij, koj yuav tsum xyuas kom tseeb tias koj muaj cov kab hauv qab no - qee cov kuj yuav muaj:

pib wlan0 cia-hotplug wlan0 iface wlan0 inet phau ntawv wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

Nias Ctrl + X tawm thiab txuag tau cov ntaub ntawv. Koj yuav raug nug yog tias koj xav tau "txuag hloov kho tsis tau", qhov no txhais tau tias "Koj puas xav khaws cov ntaub ntawv?". Nias 'Y' thiab ces ntaus nkag mus rau hauv tib lub npe.

Kho cov ntaub ntawv WPA

Cov ntaub ntawv no yog qhov chaw uas koj qhia koj tus Pi uas txuas rau, thiab tus password rau lub network.

Nyob rau hauv lub davhlau ya nyob twg, ntaus hauv cov lus txib nram qab no thiab nias sau:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Yuav tsum tau muaj ob peb kab ntawm cov ntawv nyeem hauv cov ntaub ntawv no. Tom qab cov kab no, sau cov ntawv tom qab ntawm no, ntxiv rau koj cov ntaub ntawv qhia txog qhov network uas tsim nyog:

Network = {ssid = "YOUR_SSID" proto = RSN key_mgmt = WPA-PSK pairwise = CCMP TKIP pab pawg = CCMP TKIP psk = "YOUR_PASSWORD"

YOUR_SSID yog lub npe ntawm koj lub network. Qhov no yog lub npe uas tawm los thaum tshawb nrhiav WiFi, xws li ' BT-HomeHub12345 ' lossis 'Virgin-Media-6789 '.

YOUR_PASSWORD yog tus password rau koj lub network.

Koj tuaj yeem tau ntau ntau cov blocks yog tias koj xav tau koj Pi mus txuas rau sib txawv tes hauj lwm nyob ntawm seb koj qhov chaw nyob.

Kauj ruam kauj ruam: Tua kev tswj fais fab

Yog hais tias koj muaj teeb meem nrog koj tus WiFi adapter xa kev sib txuas los yog ua neeg tsis haum, nws yuav yog tus tsav lub hwj chim tswj qhov chaw ua rau koj muaj teeb meem.

Koj tuaj yeem tua fais fab kev tswj los ntawm kev tsim cov ntaub ntawv tshiab nrog ib kab ntawv ntawm nws.

Sau cov lus txib nram no los ua cov ntaub ntawv tshiab no:

sudo nano /etc/modprobe.d/8192cu.conf

Tom qab ntawd nkag mus rau kab hauv qab no:

xaiv 8192cu rtw_power_mgnt = 0 rtw_enusbss = 0 rtw_ips_mode = 1

Ib zaug dua tawm cov ntaub ntawv siv Ctrl + X thiab tseg nyob rau hauv tib lub npe.

Reboot koj tus txiv pos

Qhov ntawd yog txhua yam uas koj yuav tsum tau ua kom muaj teeb tsa WiFi adapter, yog li tam sim no peb yuav tsum reboot Pi rau tag nrho cov kev hloov no rau hauv cov nyhuv.

Ntaus cov lus txib nram qab no hauv lub davhlau ya nyob twg kom rov tua dua, ces ntaus ntaus:

sudo reboot

Koj Pi yuav tsum pib dua thiab txuas mus rau koj lub network li ntawm ib feeb los yog li ntawd.

Tshawb Fawb

Yog tias koj Pi tsis txuas, nws muaj ob peb yam khoom uas koj yuav tsum tau xyuas:

Fais fab mov - sim ib qho txawv, muaj zog dua. WiFi tuaj yeem xav tau ntawm lub hwj chim.
Adapter - puas yog nws siv kom zoo? Pi's USB ports tuaj yeem nruj heev thaum siv thawj zaug.
Adapter - nws puas tau tshaj? Kuaj yog tias nws tau sau rau ntawm no.
Network - Puas yog koj lub network? Lwm cov khoom siv txuas nrog?
Network - ob zaug saib cov ntsiab lus uas koj nkag mus rau hauv cov ntaub ntawv supplement
Reboot - sim dua, yog thaum
