lol configuring an openwrt router is tricky... i got my dual essid setup replicated from the old router (one wpa2, another unsecured with mac whitelist for older devices that can't use wpa2) talking fine to my fiber modem and i can connect to the internet from it now
buuuuut ...... i can't access the router config itself from wifi now hahah
aha i think i did it :P just disable wan from wifi, because what was happening was wifi devices would actually get patched through to the wan zone instead of lan, which is odd but caused lan and wan devices not to talk to eachother
now wifi devices are going to lan and getting internet access properly :3 hopefully that solved everything
