Hey all,

 

I have a GL Inet Flint 3 WiFi Router, which is connected to a data point in my home.
From another data point, I have a switch connected.
And I have a connection from Switch to TP Link EAP 773 Access Point.
 

ie: Router -> Data Point -> Data Point -> Switch -> TP Link AP


When powering on the AP, I cannot connect to the default AP WiFi network on it, in order to configure it in the app.
I am trying for standalone mode. I just get "Could not assign an IP Address" on my device when connecting to the default AP WiFi.
 

I've reset the AP multiple times, tried it also with no LAN cable plugged in -- all to no avail. I keep getting "Could not assign an IP Address" when connecting to the default AP WiFi. I haven't been able to see anything on the app.
 

Lights on the device are solid blue, and every 5 seconds or so, it blinks once, and then goes solid blue again for the next 5 seconds.
 

I have 2 new Access Points, they're both doing the same thing.

I have tried powering with Unify PoE++ Adaptor, and 2 different DC power adaptors. Also tried different ethernet cables that are confirmed working with other devices.
 

Could anyone please help. Im not sure what I'm missing here.

Hi  @sierra117 

 

Thanks for posting here:

The EAP is usually plug-and-play, if you get no internet access from the EAP, 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: https://www.tp-link.com/support/faq/3083/

 

For your situation, please focus on step4 and let us know the results.

 

BTW, what do you mean by data point? What kind of devices are they?
