Your TP-Link router broadcasts a 2.4GHz and a 5GHz Wi-Fi network. These can be separated to allow you to assign your devices to the network that best suits them or merged into a single network so your devices automatically select the best band to use. Follow this guide to separate or merge your Wi-Fi bands.
1. Connect your computer, phone, or tablet to the TP-Link router via wireless (FlashRouter24 / FlashRouter50) or via ethernet cable to one of the LAN ports on the router.
The FlashRouter WiFi password is printed on the sheet that came with the router and is set to Wireless#[First 5 characters of your router MAC]. The router MAC can be found on the bottom of your router if you cannot locate the sheet. For e.g. if your MAC is 1459C07E70A8 then your WiFi password is Wireless#1459C
Be sure to capitalize the W.
2. Once connected via wireless or ethernet on your device open your browser and go to the TP-Link firmware settings.
3. Enter tp-link as the admin password to access the TP-Link firmware settings.
4. Click Wireless.
5. Check the Smart Connect checkbox to merge the two Wi-Fi bands. Uncheck the Smart Connect checkbox to separate the two Wi-Fi bands. If you have the two Wi-Fi bands separated make sure the Network Name (SSID) fields have different names for 2.4GHz and 5GHz bands. Click Save.
6. Connect your devices to the new wireless network.
