Hello, I live in a shared house with many roomies. Recently I've been having problems with others messing with my chromecast connection while casting content to my tv. I set the guest mode off but still seems people can try and cast stuff to my chromecast which results in me ending up logged out and having to reconnect the streaming service and start the show again. It's a real pain. So I heard creating a VLAN will address just that. I installed OpenWRT 22.03 on my old Asus RT-N56U that's been unused for quite some time. I've spent hours and hours on youtube watching tutorials on how to create a VLAN with no luck. The main problem seems that I can't manage to make it broadcast internet effectively as access point. However it looks like under some configuration, among the hundreds I've tried, it started broadcasting a working internet signal overnight. Went to bed with it not working and in the morning it was giving a working internet connection.
In escence what I need to create is a simple VLAN for my handful of devices: a chromecast, a smartphone, my PC, my tablet and it'd be cool to attach a hardrive to the router to create a Plex media server. My first hundred tries focused on configuring the router as an access point but then I understood making it a switch was the correct option but the few tries at that have not worked either.
Can someone please point me to the right direction? I'm about to give up. Thanks in advance.
I'm past the scan/wan creation phase. I'm attaching my wan configuration screen and my firewall screen.
Since I'm a newbie, the system would let me attach only one image. I decided to attach the firewall screen.
