No I did do the thing with the mac addresses the first time but I didn't know how to secure it but this time I looked up the master routers security settings and matched them with that so all I had to do was those to things.

It's weird now I don't have local internet connection via ethernet from the wireless router or from the master router
and I just tried connecting in my sleepout now and I can't connect only getting limited access or no internet access tried diagnostics reseting wireless adapter nothing it's odd that it was working around lunchtime but now it isn't btw connected to the main router at the moment still in sleepout
