Mmene Mungakhazikitsire Adapi ya WiFi ya USB ndi Raspberry Pi

Lankhulani pa intaneti ndi Pi-Raspberry Yanu

Pa Raspberry Pi iliyonse yatsopano ya Pi 3, kulumikiza pa intaneti kunakwaniritsidwa mwa njira imodzi - kulumikiza kudzera pa doko la Ethernet kapena kugwiritsa ntchito adapotasi ya USB WiFi.

Nkhaniyi ikuwonetsani momwe mungakhazikitsire USB ya WiFi ndi Pi yanu, pogwiritsa ntchito Edimax EW-7811Un mu chitsanzo ichi.

Lumikizani Zidalama

Chotsani Raspberry Pi yanu ndi kulumikiza adapotala yanu ya WiFi muzitsulo zilizonse za Pi zomwe zilipo, Ziribe kanthu kaya mumagwiritsa ntchito chipika chanji.

Tsopano ndi nthawi yolumikiza wanu makina ndi chinsalu ngati simunachite kale.

Yambani Raspiberi yanu Pi ndikupatsani mphindi kuti mutsegule.

Tsegulani Terminal

Ngati Pi boots anu ku terminal mwalephera, tambani sitepe iyi.

Ngati Pi boots anu ku Raspbian desktop (LXDE), dinani chizindikiro cha terminal mu taskbar. Ikuwoneka ngati chowunikira ndi makina akuda.

Sinthani Faili la Network Interfaces

Kusintha koyamba kupanga ndi kuwonjezera mizere ingapo ku fayilo ya intaneti. Izi zimakhazikitsa adapadata ya USB kuti igwiritsidwe ntchito, ndipo kenako tidzatiuza zomwe tingagwirizane nazo.

Mu otsiriza, yesani mu lamulo lotsatila ndi kufikitsa kulowa:

sudo nano / etc / network / interfaces

Fayilo yanu idzakhala ndi malemba ena, omwe angakhale osiyana malinga ndi Raspbian yanu. Mosasamala kanthu, muyenera kutsimikiza kuti muli ndi mizere inayiyi - ena akhoza kale kukhalapo:

auto wlan0-hotplug wlan0 wface wlan0 inet buku wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

Dinani Ctrl + X kuti mutuluke ndi kusunga fayilo. Mudzafunsidwa ngati mukufuna "kusunga buffer", izi zikutanthauza "Kodi mukufuna kusunga fayilo?". Onetsani 'Y' ndiyeno mugonjetseni kulowa kuti muzisunga dzina lomwelo.

Sinthani Fomu Yothandizira WPA

Fayilo yonyalanyazayi ndi kumene mumauza Pi yanu yomwe makanema akugwirizanako, ndi liwu lachinsinsi la intaneti.

Mu otsiriza, yesani mu lamulo lotsatila ndi kufikitsa kulowa:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Payenera kukhalapo mizere ingapo ya malemba mu fayilo iyi. Pambuyo pa mzerewu, lowetsani malemba omwe akutsatirawa, ndikuwonjezerani tsatanetsatane wa makanema omwe akufunikira:

network = {ssid = "YOUR_SSID" proto = RSN key_mgmt = WPA-PSK pairwise = CCMP TKIP gulu = CCMP TKIP psk = "YOUR_PASSWORD"

YOUR_SSID ndi dzina la intaneti yanu. Limeneli ndilo dzina limene limabwera pofufuza WiFi, monga ' BT-HomeHub12345 ' kapena 'Virgin-Media-6789 '.

YOUR_PASSWORD ndichinsinsi pa intaneti yanu.

Mukhoza kuwonjezera ma blocks ambiri ngati mukufuna Pi yanu kugwirizanitsa ku mapulogalamu osiyanasiyana malingana ndi malo anu.

Gawo Loyenera: Tembenuzani Kutaya Mphamvu

Ngati muli ndi vuto lililonse ndi adapita yanu ya WiFi yosiya kugwirizana kapena kusamvera, ikhoza kukhala malo okonza kayendetsedwe ka mphamvu kukupangitsani mavuto.

Mungathe kutsegula kayendedwe ka mphamvu mwa kungopanga fayilo yatsopano ndi mzere wa malemba mkati mwake.

Lowetsani lamulo lotsatila kuti mupange fayilo yatsopanoyi:

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

Kenaka lowetsani mndandanda wa malemba awa:

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

Tulutsanso fayilo pogwiritsa ntchito Ctrl + X ndi kusunga pansi pa dzina lomwelo.

Bweretsani Anu Rasipiberi Pi

Ndizo zonse zomwe mukufunikira kuchita kuti mukhazikitse adapita ya WiFi, choncho tsopano tikufunika kubwezeretsa Pi kuti awonetse kusintha kumeneku.

Lembani lamulo lotsatila mu terminal kuti muyambirenso, kenaka pitani kulowa:

sudo reboot

Pi yanu iyenera kuyambanso ndikugwiritsira ntchito makanema anu mkati mwa miniti kapena kuposa.

Kusaka zolakwika

Ngati Pi yanu sagwirizana, pali zinthu zochepa zomwe muyenera kuzifufuza:

• Kupereka Mphamvu - yesani mphamvu yamphamvu, yamphamvu. WiFi ikhoza kukhala yofuna mphamvu.
• Adapter - kodi ili yoyenera bwino? Mipu ya USB ya Pi ingakhale yolimba poyambirira.
• Adapter - kodi ikugwirizana? Fufuzani ngati zalembedwa pano.
• Mtanda - Kodi makanema anu ali pamwamba? Kodi zipangizo zina zimagwirizanitsidwa?
• Pulogalamu - yang'anani kawiri zomwe mwalowa mu fayilo ya supplicant
• Yambani - yesani kachiwiri, ngati mutero
