Hi,

Are all three LED indicator lights on both TL-PA717 devices solidly lit?

  @woozle 

Yes, all three LED indicator lights on both of my TL-PA717 devices are solidly lit, indicating that they are properly connected and powered on. The core issue seems to be related to WiFi connectivity, even though the powerline network appears to be functioning correctly based on the indicator lights.

To provide more details:

• The Power LED is on, showing the device is powered up.
• The Powerline LED is solid, indicating a good connection to the network.
• The Ethernet LED is also solid, suggesting a successful link to the connected device.

Despite this, I'm still unable to access the internet via WiFi from the extended network. It's as if the devices are communicating well with each other but not providing internet access through the WiFi connection. I'm looking for any suggestions on how to resolve this WiFi connectivity issue. Could it be a configuration problem, or is there something else I'm missing?

Thank you for your attention to this matter!

What kind of device is providing the Wi-Fi connectivity?

Is you network topology like this? :

  @woozle 

 thank you for the diagram; it accurately represents my network setup. I am using a TP-Link Wi-Fi access point connected to the TL-PA717 at the end of the chain, and I've actually tried two different TP-Link Wi-Fi APs to rule out the possibility of a faulty unit.

Both Wi-Fi APs exhibit the same issue—they show as connected with good signal strength, but there's no internet connectivity. I have verified that the APs work correctly when connected directly to the router via Ethernet, which leads me to suspect the issue might be with the communication between the TL-PA717 and the Wi-Fi APs.

Is there a specific setting on the TL-PA717 that I need to configure for compatibility with TP-Link Wi-Fi APs, or could there be an issue with the TL-PA717 units themselves? Any guidance on this would be greatly appreciated.

So, if you plug the cable marked with the blue arrow into the Wi-Fi AP, then everything works fine, but if you plug the cable marked with the red arrow into the Wi-Fi AP, then there is no Internet, right?  That is indeed very weird. 

There are no special settings for connecting a Wi-Fi AP via Powerline. It shouldn't matter whether you connect a PC, a video game console, a TV or a Wi-Fi AP to the second TL-PA717.

But in case there is something particular about those Wi-Fi APs, do you own any other device that you could connect to the second TL-PA717 via Ethernet cable, just for a test?

By the way, apart from there being no Internet available via the Wi-Fi AP, is there any local network connection at all? For example, are you able to open the router's webpage when you are connected to the Wi-Fi AP? Or does the router see the Wi-Fi AP and any devices that are connected to the Wi-Fi AP? (you would have to log into the router to determine that)

When I connect my laptop directly to the second TL-PA717 unit using an Ethernet cable, I do indeed have an internet connection, but the speed is extremely slow at around 0.40 Mbps. However, the TP-Link app indicates a connection speed of 60 Mbps between the powerline adapters.

Interestingly, while connected directly to the TL-PA717 via Ethernet, my laptop can ping external servers and access local network resources, such as the router's configuration page. So, there is some level of connectivity being provided through the powerline network. However, this functionality doesn't extend through the Wi-Fi AP, where I encounter the issues.

Given this, could there be a quality of service (QoS) setting or another configuration on the router or powerline adapters that I need to adjust? Or is it possible that the powerline communication is experiencing interference or signal degradation that's causing this drastic drop in speed?

To confirm whether that is the reason for the problems you are experiencing I suggest you take both, the second TL-PA717 and the Wi-Fi AP, and plug them in a wall outlet that is much closer to the location of the first TL-PA717 (the one connected to the router). Then check again if things start working now and how much the connection speed shown by the TP-Link app has improved.
