Generally, whenever the multiple devices (bands) broadcast their wireless network with the same name (SSID). In that case, you can only see one network name in the wireless list of your end-devices.
For example, if we take an example of a Network name of your router is 'TP-Link_Router', and you also configure your Range extender with the same SSID, you will only see 1 wireless name in the list of your mobile device, though your router and extender have 2 wireless signals in total. And then, if you connect your phone to this network, you may not know which front device your phone is connecting to.
How to check?
After your extender has already been connected to the router, and also the signal/RE Light is lit: If you haven’t manually change the SSID of the extender, the default SSID will be the same to the main router, of adding the “_EXT” at the end of the router’s SSID. For example, if the SSID of your router is “TP-Link_Router”, the default SSID of the extender would be “TP-Link_Router” or “TP-Link_Router_EXT”. So, you can check out the wireless settings of your phone and you need to check if you can find the specific SSID of your Range Extender.
If you have manually changed the SSID of the extender, it's what you simple setup.
How to configure the SSID of the extender again?
You can log in the webpage of the extender to configure it again, or just reset it and follow the quick setup wizard to set it up again.
Steps to follow:
- Log in the web management page of the range extender RE450.
NOTE: If you want to configure the settings after Quick Setup, you can open up a web browser and type “http://tplinkrepeater.net” and log in with the login password that you set for the extender. This article is only applied to the situation to configure the range extender from scratch.
Follow the steps below for RE450
Plug the extender into a wall jack near your main router, and then wait until the Power LED is solid on.
Connect your computer to the extender's wireless network.
TIPS: Before this connection, check out the SSID (network name) on the label of the extender.
