Mediatek MT6712U si Hostapd

Salut all

Incerc sa folosesc Hostapd impreuna cu Mediatek MT7612U insa primesc urmatoarea eroare:

Configuration file: /etc/hostapd/2g.conf
nl80211: Could not configure driver mode
nl80211: deinit ifname=wlx0013ef6f0af7 disabled_11b_rates=0
nl80211 driver initialization failed.
wlx0013ef6f0af7: interface state UNINITIALIZED->DISABLED
wlx0013ef6f0af7: AP-DISABLED
wlx0013ef6f0af7: CTRL-EVENT-TERMINATING
hostapd_free_hapd_data: Interface wlx0013ef6f0af7 wasn't started

Cu toate acestea inainte de a incerca sa pornesc hostapd am verificat ca interfata este in monitor mode, este up si cu IP static, isc-dhcpd vede interfata fara probleme.

modulele care vin cu kernel 4.19 sunt incarcate
mac80211   835584  4 mt76,mt76_usb,mt76x2u,mt76x2_common
cfg80211   774144  4 mac80211,mt76x2u,mt76x2_common,88XXau

Aceiasi configuratie hostapd functioneaza fara probleme cu RTL88XXau (alt adaptor).

Sa inteleg ca nu suporta driverele nl80211 ?

Sugestii ?

Mersi.

Ai rulat

airmon-ng check kill

?
Poate sunt procese care folosesc încă interfața.

Am rulat insa cu acelasi rezultat.

A pus pe debug:

Am gasit problema... insa nu si rezolvarea... inca...

Problema:
Am gasit in comparatie cu alt adaptor wifi care functioneaza cu hostapd
Cel care functioneaza are:
Supported interface modes:
   * IBSS
   * managed
   * AP
   * monitor
   * P2P-client
   * P2P-GO

Cel care nu functioneaza are:
Supported interface modes:
   * managed
   * monitor

Cand initializeaza hostapd incearca sa treaca interfata in mod ap si evident ca apare eroare pentru ca nu suporta modul respectiv.
Partea nostima este daca incerc sa setez manual in mod ap primesc mesajul ca sa folosesc un soft precum hostapd
/etc/hostapd# iw wlx0013ef6f0af7 set type ap
You need to run a management daemon, e.g. hostapd,
see http://wireless.kern...ntation/hostapd
for more information on how to do that.
Adica ma sfatuieste sa folosesc un soft ca hostapd insa driverul nu suporta modul ap

Sugestii ?

Da, e de la driver atunci.
Încearcă cu ăsta: https://github.com/openwrt/mt76

Nu are documentatie... nici macar un readme.

~/mediatek/mt76# make
make: *** No targets.  Stop.

E prima data cand compilezi ad-labam un soft sub GNU/Linux?

Ca sa compilezi ad-labam rahatul ala pentru GNU/Linux nu e asa simplu cum te astepti. Ca ai niste modificari de facut inainte de a il compila.

LE: Sigur e MT6712U sau e MT7612U? Ca e o mica diferenta intre 67 si 76.

@Kagaroth
Din cate stiu eu asta intra la documentatie... macar un readme... sau se presupune ca trebuie sa stiu ce gandesc programatorii ?
Daca stii cum te rog precizeaza.
Ai dreptate am trecut gresit... este vorba de MT7612U.

Intre timp am gasit o informatie care ar lamurii problema insa nu stiu daca este si reala:
https://archlinuxarm...hp?f=65&t=14058
Eu folosesc kernel 4.19

Link-ul de  mai sus, postul #5, are un Makefile asociat dar acolo se presupune ca se compileaza modulul ala la pachet cu openwrt. din acest motiv lipseste sectiunea necesara din acel Makefile. Gasesti modulul pe site-ul Mediatek, pentru 7612U, la fel gasesti si prin kernel modulul inclusiv un link pentru a se descarca firmware-ul. Sub Arch in AUR vad doar 7610U si un 7630e, banuiesc ca e vorba de 7610U. Nu stiu pentru ce distro vrei tu pachetul sau pe ce distro vrei sa il compilezi.

https://d86o2zu8ugzlg.cloudfront.net/mediatek-craft/drivers/MT7612U_DPO_LinuxSTA_3.0.0.1_20140718.tar.bz2

Nu m-am chinuit foarte tare sa il compilez. Oricum nu am jucarie x86 cu chipset mediatek ca sa am nevoie de modulul ala. Banuiesc ca e versiune pe 32 de biti si e nevoie de multilib ca sa il compilezi. Eu nu tin repo-ul multilib activ asa ca nu am bilbliotecile necesare compilarii lui (probabil). Vezi daca ii dai de cap.
