Po čisté instalaci nejde wifi

[Levin]

Ahoj,

nově jsem si udělal čistou instalaci a nejde mi wifi. Wifi se normálně připojí na mou síť, ale poté se již nelze připojit k internetu, hází to chybu k načtení stránky.
Internet mi funguje pokud jsem připojený kabelem a WIFI mám zaplou, nechápu vůbec proč. Kabel navíc při tomto stavu hlásí stav Nespárováno. Níže dávám výpis.

A v jakém to je stavu? Tohle vypadá, že je to připojené zároveň drátem i Wi-Fi a hlavně že to zrovna funguje. Potřebujeme vidět nefunkční stav při připojení na Wi-Fi.

JJ, bylo zapnuto obojí.

Tady dávám výpis jen se zaplou WiFi.

Ak môžem poprosiť hod tu výpis.

Kód [Vybrat] Rozbalit

cat /etc/network/interfaces

cat /etc/NetworkManager/NetworkManager.conf

[Levin]

Výpis předchozích dvou příkazů jen při zaplé wifi.

Kód [Vybrat] Rozbalit

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[Brano Dohoda]

na začiatok riadkov daj znak #

Kód [Vybrat] Rozbalit

sudo nano /etc/network/interfaces

Kód [Vybrat] Rozbalit

# allow-hotplug eth0
# iface eth0 inet dhcp

a v tomto druhom zmeň false na true.

Kód [Vybrat] Rozbalit

sudo nano /etc/NetworkManager/NetworkManager.conf

Kód [Vybrat] Rozbalit

managed=true

V termináli potom dáš uložiť CTRL+X a potom písmenko Y ako yes. Reštart PC a skus potom budeš mohol managovat siete vypínať a zapínať.

[Levin]

Díky, tímto se to vyřešilo.
