OpenWrt - tryby pracy sterownika ath9k
wariacje na temat konfiguracji sieci w OpenWrt
Ostatnia zmiana: 2011-03-05 16:04

1. Tryb AP
 1.1. /etc/config/network
 1.2. /etc/config/wireless
2. Tryb APClient (WISP)
 2.1. /etc/config/network
 2.2. /etc/config/wireless
3. Tryb AP + APClient
 3.1. /etc/config/network
 3.2. /etc/config/wireless
4. Tryb AP + VAP
 4.1. /etc/config/network
 4.2. /etc/config/wireless
5. Tryb WDS
 5.1. AP
 5.2. Klient
6. Bridged Client

W przedstawionych konfiguracjach brakuje sekcji lo, switch oraz kompletnej zawartości sekcji wifi-device. Należy je uzupełnić stosowanie do posiadanego sprzętu. Bridged mode nie działa sterowniku ath9k.

Założenia:
- lan: eth1
- wan: eth0
- wlan: kanał 5, kodowanie wpa2/aes
            dla trybu AP: hasło 1234567890, ssid: eko_one_pl
            dla trybu APClient: hasło 0987654321, ssid: ISP

Komputery podłączone kablem do klienta uzyskają adres 192.168.1.x, czyli z serwera dhcp na AP. Adres na kliencie ustawiony jest z innej puli tylko żeby można było się do niego podłączyć w razie potrzeby.
