If you're using our Network Box, and haven't already done so, you could change your 5 Ghz SSID to split your bands, which technically would create a second SSID you can connect to (although it's still the same LAN). If you're looking to add an entirely separate secondary Network (which could potentially cause double NAT issues), you'd need to set up a second router. Do note that having multiple routers broadcasting wireless at the same time can also cause interference.
