@At Work Obrigada pela resposta, não esta ainda a funcionar mas o problema não era esse porque eu mal aplicava o router morria, nem por cabo, nem por wireless, nem por nada. Mas era mesmo problema de firmware (ate pode ser do router) porque basicamente mal voltei a meter o firmware de origem e depois voltei a meter OpenWRT tudo funcionou.
Por funcionar entenda-se o router não morrer, já criei as VLAN já atribui IPs diferentes em cada porta, configurei Internet em duas delas e funcionam mas continuo a poder aceder a todas as redes.
Neste momento estou na porta 2 com IP por ex 192.168.3.10 e consigo pingar as outras rede e aceder ao router em todas as gamas se meter 192.168.1.1 ele dá à mesma.
