I recently installed AdvancedTomato Version 3.5-140 on a Netgear R6300v2. Ever since, I keep seeing this open, hidden-SSID network show up (such as on Windows or Android devices). It's on the same channel as my 2.4 GHz wifi, and if I change channels, it moves with it. If I turn my router off, it goes away. So I conclude it is being generated by my router. I was trying to configure a VLAN, and thought it might be related to this. I deleted all the VLANs, but it was still there. I went so far as to wipe the NVRAM and reconfigure manually. As soon as I enable wireless, the hidden network shows up. The network shows up with no security, although since the SSID is hidden I can't connect to it. Any idea what's going on?
