Indlela Yokusetha I-Adapter ye-WiFi ye-USB enePaspberry Pi

by URichard Saville

Xhuma kwi-intanethi ngeParpberry yakho Pi

Kuzo zonke iinguqu ze-Raspberry Pi ngaphambili kwePi 3, ukuxhuma kwi-intanethi kufezwe ngenye yeendlela ezimbini-ukuxhuma kwi-port ye-Ethernet okanye usebenzisa i-adapter ye-WiFi ye-USB.

Eli nqaku lizokubonisa indlela yokusetha i-adapter ye-WiFi ye-USB kunye ne-Pi yakho, usebenzisa i-Edimax EW-7811Un kulo mzekelo.

Xhuma iQumrhu leQumrhu

Vala i-Raspberry Pi yakho kwaye ulungele i-adapter yakho ye-WiFi kunoma yiyiphi i-ip ye-port ekhoyo ye-USB, akunandaba nokuba yiliphi ichweba oyisebenzisayo.

Ngoku lixesha lokuxhuma ikhibhodi yakho kunye neskrini ukuba awukwenzi oko.

Vula i-Raspberry Pi yakho kwaye uyinike ingcaciso ngomzuzu.

Vula i-Terminal

Ukuba zakho iibhokisi zePi kwi-terminal ngokuzenzakalelayo, yeqa le nyathelo.

Ukuba ii-bot zakho zebhokisi kwidesktophu yaseRaspbian (LXDE), nqakraza uphawu lwesigxina kwibar yomsebenzi. Kubukeka ngathi iliso ngekrini elimnyama.

Hlela i-File Interfaces File

Utshintsho lokuqala lokwenza ukuba ukongeza imigca embalwa kwifayili ye-interfaces yefayile. Oku kuseka i-adapter ye-USB ukuba isetyenziswe, kwaye kamva siya kuxelela oko ukuxhuma kuyo.

Kwi-terminal, thayipha umyalelo olandelayo kwaye cinezela ukungena:

sudo nano / etc / network / interfaces

Ifayili yakho iza kuba neendlela ezithile zokubhaliweyo kuyo, ezinokuthi zihluke ngokuxhomekeke kwinguqulelo yeRaspbian. Kungakhathaliseki ukuba, kufuneka uqinisekise ukuba unemizila emine elandelayo-mhlawumbi sele ikhona:

auto wlan0 vumela-hotplug wlan0 iface wlan0 inet incwadi wpa-roam /etpa/supplicant/wpa_supplicant.conf

Cinezela i-Ctrl + X ukuze uphume kwaye ulondoloze ifayile. Uya kubuzwa ukuba ufuna "ukugcina ibhukisi eguquliwe", oku kuthetha ukuthi "Ngaba ufuna ukugcina ifayile?". Cinezela 'Y' uze utshise ukungena ukuze ugcine phantsi kwegama elinye.

Hlela iFayile eFunayo yeFayile

Le fayili exhasayo yilapho utshela i-Pi yakho apho umnxibelelwano ukuxhuma kuyo, kunye nephasiwedi yaloo nethiwekhi.

Kwi-terminal, thayipha umyalelo olandelayo kwaye cinezela ukungena:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Kufuneka kubekho imigca emibini kule fayili. Emva kwezi mida, faka ibhloko yecatshulwa elandelayo, ukongeza iinkcukacha zakho zenethwekhi apho kufuneka khona:

intanethi = {ssid = "YOUR_SSID" proto = RSN key_mgmt = i-WPA-PSK pairwise = CCMP TKIP iqela = CCMP TKIP psk = "YOUR_PASSWORD"

I-YOUR_SSID ligama lenethiwekhi yakho. Leli gama eliza xa usesha i-WiFi, njenge ' BT-HomeHub12345 ' okanye 'Virgin-Media-6789 '.

I-YOUR_PASSWORD yiphasiwedi yenethiwekhi yakho.

Unokongeza iibhloko ezininzi ukuba ufuna iPi yakho ukuxhuma kwiinkonzo ezahlukeneyo kuxhomekeke kwindawo yakho.

Isinyathelo sokhetho: Vala ukuLawula amandla oMbane

Ukuba unemiba kunye ne-adapter yakho ye-WiFi yehla uxhulumaniso okanye ungayiphenduli, kungenokuba isicwangciso sokulawula amandla okuqhubela umbane esibangela iingxaki.

Unokuvala ukulawulwa kwamandla ngokudala nje ifayile entsha kunye nomgca wombhalo ngaphakathi kuyo.

Faka umyalelo olandelayo ukudala le fayile entsha:

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

Emva koko faka umgca olandelayo wombhalo:

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

Phinda uphume kwakhona kwifayile usebenzisa iCtrl + X kwaye ugcine phantsi kwegama elinye.

Qalisa kwakhona i-Raspberry Pi yakho

Yiyo yonke into okufuneka uyenze ukusetha i-adapter ye-WiFi, ngoko ngoku kufuneka siqalise kwakhona iPi ukufaka zonke ezi nguqulelo.

Thayipha umyalelo olandelayo kwi-terminal ukuqala kwakhona, uze utshintshe ukungena:

sudo kabusha

I-Pi yakho kufuneka iqalise kwakhona kwaye iqhagamshele kwinethiwekhi yakho ngaphakathi kwimizuzu okanye njalo.

Ukulungisa ingxaki

Ukuba i-Pi yakho ayixhumeli, kukho izinto ezimbalwa ezicacileyo onokuzijonga:

Ukunikezwa kwamandla - zama amandla ahlukeneyo anamandla. I-WiFi inokufuna ngamandla.
I-Adapter - ingafakwa ngokufanelekileyo? Iipi ze-USB ze-Pi ziyakunzima kakhulu ekusebenziseni okokuqala.
I-Adapter - iyahambelana? Khangela ukuba ibhalwe apha.
Inethiwekhi - Ngaba intanethi yakho iphezulu? Ngaba ezinye idivayisi zixhunyiwe?
Inethiwekhi - kabini hlola iinkcukacha ozifakayo kwifayile ecelwayo
Qala kwakhona - zama kwakhona, xa kunjalo
