I started my initial Meraki Go installation yesterday with initially a GX20 gateway. I will add three GR10 access points once my wired network is up and running. I have a 350/20 Mpbs Virgin Media Business Broadband connection. There won't be FTTP in this part of London for several years yet 😞 When my two computers are directly connected to my old router, I see speeds of about 400/20 Mbps on both. One is a decade old HP Z600 running Windows 10 Pro and the other is a newly built Intel NUC11TNBi7 motherboard installed in a fanless Akasa case running Windows 11 Pro. When I connect them to the GX20, The Z600 shows a speed of about 300/20, which is a bit better than I expected. However, I only see a speed of just under 10/10 Mbps with the NUC, no matter which port on the GX20 or Cat 6 cable I use. On closer inspection of the properties of my network card (Intel I225-LM), I see the speed is displayed as only being 10 Mbps instead of the 1.0 Gbps I was seeing when connected to my old router. When I check the link speed of the port on the GX20 in the Meraki Go app, this is also showing as only 10 Mbps. I have switched around cables with the same result. I also carefully cleaned each GX20 port with a clean soft brush, but there was no debris whatsoever as it is brand new. The NUC bios and its network card driver is up to date. I also tried changing the "Speed & Duplex" manually from Auto-Negotiation to 1.0 Gbps Full Duplex and then 2.5 Gbps Full Duplex, but the speed did not change. So, it seems the speed that is being negotiated between the GX20 and NUC is only 10 Mbps. Does anyone have any idea how to resolve this?
