  @Chris7427 Thank you very much for the update.

I couldn't figure it out either. I noticed you also submitted a support ticket, so I've forwarded it to our senior engineer for further assistance.

Please check the email later for more suggestions.

Thanks a lot.

Best regards.

  @Chris7427 

Hi, can I have the model numbers of the two Ethernet PCs?

Did it help if the PC is connected to a different Ethernet port on the main Deco XE75?

Please also try to enable QOS and set it to 1000 Mbps download/upload to see whether it makes any difference.

 

Wait for your reply.

Best regards.

  @David-TP

Thanks for getting back to me

The 2 ethernet devices are a HP Probook 450 Realtek Ethernet and an Asus V16 via USB c adaptor.

Plugged into different port same result.

Also reset the whole system and made a different node the main unit and i get the same problem.

Got my old router out (Nighthawk R8000) that was replaced with the XE75 PRO and I get 900mbps up and down using exactly the same cables setup etc.

I enabled QOS and its the same

 

I'm very happy with the speeds I'm getting via Wifi and can easily cope with just using Wifi but you cant beat a cable connection for reliablity

 

I work in IT and feel a little embarrassed that I'm having to resort to asking on a forum but I'm lost for ideas now.
