If you are unable to see the broadcasted wifi network from your TDC wifi router with some or no devices, then check the following setting on your router:
Router navigation: use 'menu' to scroll down, and 'power' to accept.
1. Hit the 'menu' button on top of your router
2. Scroll down and open '5G/2.4G'
3. Make sure the option '2.4G' is marked - if its not, scroll down and mark it.
Your router will briefly apply the changes, and you should then be able to see the network on your device.
