Hi  @HoldingA 

Below is a guide on how to access the EAP's web management page:

How do I login to the web management page of the EAP Series products (Standalone mode)?

The EAP is usually plug-and-play. If you can't get Internet access when connecting to the EAP's wifi network,  please firstly confirm the main Router is working fine. Then check the points below and see if it helps:
    1. Ensure the EAP is hardwired to the router via an Ethernet LAN cable, use a standard CAT5 above cable for the connection. Usually, we can see a corresponding LED light up on the Router.
    2. Test the EAP's SSID with other wireless clients, eliminate the issue is from a specific client.
    3. Check the IP info on the wireless clients. To access the Internet, the clients need to get Default Gateway (Router) and DNS Server from your network through the EAP.
    4. Unplug the EAP, and connect a PC instead to the Router with the same Ethernet cable, check the IP info obtained on the PC and confirm it can get internet access.
    5. Reset the EAP: with the EAP powered on, use a pin to press and hold the reset hole for about 8 seconds until the LED flashes green-red-yellow to factory default settings.
    6. Repeat step 1)-4) if you still get no Internet access from the EAP, this is a detailed FAQ for more troubleshooting tips:
