Is something not right with your GL iNet GL MT300N v2 setup? Check the hardware connections first of all. Start with the power adapter: Ensure it is firmly connected to your router and a good source of power. Next, look for damage or looseness in the Ethernet cable that connects your router to your modem or an existing network. If you are configuring it over Wi-Fi, please ensure to place your device attached to the network and close enough to a router's Wi-Fi signal. In case all of this does not work for you, use a factory reset of the router and then continue trying your luck on configuring the GL iNet GL MT300N V2.
