Configurando repetidores Wi-Fi com vários SSIDs

--- a humbly committed student 2019/01/19 10:31

O objetivo deste artigo é mostrar aos usuários como configurar um roteador principal e vários pontos de acesso para repetir vários SSIDs por meio do uso de comutadores VLAN marcados.

Este exemplo contém um roteador principal que fornecerá os SSIDs Wi-Fi e o serviço DHCP e dois roteadores configurados como pontos de acesso. Neste exemplo, o roteador Linksys WRT 3200acm com OpenWrt 18.01 foi usado para todos os dispositivos.

Esses procedimentos podem ser realizados principalmente na GUI LuCi, mas, como não consigo anexar capturas de tela, eu fiz a configuração através dos arquivos de configuração dos roteadores localizados em /etc/config durante uma sessão SSH em cada roteador.

Recomenda-se familiarizar-se com os seguintes artigos do wiki para executar esta tarefa.

Esta é uma topologia de rede para este exemplo:

Exemplo de topologia de rede

Os SSIDs foram criados e conectados à respectiva interface de rede. Cada interface de rede foi adicionada ao seu próprio ID de VLAN específico.

Os dois pontos de acesso foram configurados para usar a porta WAN para receber a conexão de uplink marcada da porta de interface marcada do roteador/hop anterior. Fiz isso para me permitir utilizar as 4 portas da LAN, o que me deu mais portas para conectar dispositivos.

Torna-se um jogo compatível para garantir que o número de ID da VLAN anexado a cada uma das interfaces Wi-Fi seja consistente em todos os dispositivos, ou seja, privado na VLAN1 (eth0.1), convidado na VLAN3 (eth0.3), ou seja, na VLAN4 (eth0.4) etc. para que cada roteador saiba a existência das VLANs.

Lista de SSIDs de Wi-Fi:

Privado: SSID = Magick Mushroom, Jogos
Convidado: SSID = Escravo
Tor: SSID = tor

Detalhes do Switch

VLAN ID	Upstream side:HW switch ↔ eth1 driver		Downstream side:HW switch↔physical ports
	CPU (eth0)	cpu (eth1)	LAN1	LAN2	LAN3	LAN4	WAN
1	tagged	off	untagged	untagged	untagged	tagged	off
2	off	tagged	off	off	off	off	untagged
3	tagged	off	off	off	off	tagged	off
4	tagged	off	off	off	off	tagged	off

*Dica: Para determinar a CPU da WAN dos roteadores quando houver várias CPUs listadas, use a GUI Luci e navegue até Rede > Switch e veja qual linha tem a CPU marcada e a WAN sem marcação, juntas, por padrão. Outra maneira é usar a GUI Luci para navegar em Rede > Interfaces e ver qual interface é usada nas Configurações físicas da WAN

1. Crie VLANs extras para corresponder à tabela acima. A interface LAN4 foi configurada para ser identificada com números de ID da VLAN. A LAN4 está retransmitindo o uplink para o próximo roteador (o roteador de médio porte).
