I have a fun issue if I connect my PC to the KPN router via LAN I get 920mb/s but if I connect that same cable via a second router or a LAN splitter the PC the speed drops to 90mb/s on LAN.

The wifi is running at 700-800mb/s on the same LAN but the best I can get the PC is to 90mb/s.  I tried to adjust the Ethernet connections (speed & duplex) from Auto but I can only set it to 100 mbs not 1.0G as a value.  

The link speed receive/transmit seems to be defaulting to 100/100 mbps if I run the LAN cable into any other device such as LAN/Splitter.

Hi @David Iwanow, what happens if you connect the PC directly to the modem?  So without a switch etc in between.


Greetings, so directly connecting PC to Lan gives full speed 1Gig link speed which makes it all very weird. 


Then there is something in your network that has a maximum speed of 100 mbits. The switch, or something else for example. Because it’s not the PC, the modem or the Ethernet port
