@TadBR 

Thanks for the feedback.

Could you please send an email to support.forum@tp-link.com ----Subject [Forum ID 613804] XE75 V2 Capping Ethernet to 100Mbps with the following details:

1. Can I have a picture of your network topology, for example:

2. Please also save the pictures of the network map and Mesh Backhaul type on the Deco APP, such as

3. Can I have more details about the Backahul Link speed issue? or could you please help me check the following information:

• If there is more than one satellite XE75, were all the satellite XE75s capped at 100m/s?
• Did these satellite Deco XE75s stay on 100m/s all the time, or did it randomly jump between 1G and 100m/s?
• Are you able to stably reproduce this issue?
• Have you changed the Ethernet cables or confirmed all the cables are firmly connected?

Wait for your reply.

Best regards.

Hi, Thomas,

As for the UPNP settings, actually, I am a little curious. Since both satellite XE75 pros are connected to the main XE75 pro, then to BT Smart Hub2 via 2.5G port, so when you disabled "Extend UPnP Security”, is there any influence on the main XE75 pro?

 "I've since rewired by network setup to use the one fully functioning port on each satellite to then wire everything off of." I think you are trying to say now that both satellites XE75 pro are connected to the main Deco via their own 2.5G ports, right? Previously you mentioned that if the Decos are all connected via 2.5G ports, the Ethernet link speed could reach 1G/s and the iPad could also get 900m/s via speedtest via Ethernet cable, no longer capped at 100m/s. Is it still the case?

Thank you very much.

best regards.

Hi, Thanks for the message. I also got your support ticket.
The engineers are working on this issue and so far, there hasn't been a fix yet. But since the feedback is increasing, I think a fixed firmware will be ready soon.
Could you please help me check the details mentioned here? (You could update the email with the required information)

Hi, Thanks for the update. yes, There will be an official firmware.

I am also waiting for further news from the engineer on whether the beta firmware for Deco XE75 Pro is ready to be uploaded to the community for the test.

Best regards.
