I've got an ASUS RT-N66U running Tomato Firmware 1.28.0000 MIPSR2-115 K26 USB AIO-64K. This thing has been rock solid for me for several years. I only use the 2.4Ghz radio. I have a main VLAN bridged to our main wifi that my wife and I use. I have a second VLAN bridged to a second virtual SSID for our son, which gives me some control over his internet access and keeps him and his friends off of our network. I am trying to create a third virtual SSID as a segregated network for our growing internet of things. I followed the exact same process that I followed when I created the VLAN and virtual SSID for our son's wifi. I can see the SSID, but both my phone (Galaxy S7) and Windows 7 laptop won't connect to it. I don't get any errors. My phone just says "connecting" for a bit, then stops, then says "connecting" again, then stops and connects back to our primary wifi. My laptop just tells me that it is unable to connect to the SSID. The troubleshooter offers no information. I've spent a good chunk of time googling and searching these forums. The most likely explanation is that I'm just completely missing something obvious. Though I'm starting to wonder if there is a Tomato bug. I did find one older post that said there is (was?) a known VLAN bug if you did not have the Virtual Wireless interfaces in the right numerical order; but, from what I can tell mine or in the correct order. Here are some relevant screenshots: Basic>>Network>>LAN: https://snag.gy/5Sbnev.jpg Advanced>>VLAN: https://snag.gy/0e4hYz.jpg Advanced>>Virtual Wireless: https://snag.gy/Rr62Ws.jpg I've tried entering an incorrect password but I still don't get an error, so I'm not even getting to the step of authenticating. I'd appreciate any suggestions. Like I said, I am probably missing something obvious.
