DHCP connection does not work at 1 GBit/s but at 100Mbit/s it does?
Good morning.
I wanted to change my Ethernet to 1 Gbit/s because I have a 400 Mbps connection. However, when I set the duplex to 1 Gbit/s, the diagnostics tell me that the DHCP server cannot be reached. At 100 Mbps, the connection works fine. I have an Asus RT-AX57 router and a CAT 7 cable, so that can't be the problem. I've also connected another PC to the same port, and 1 Gbit/s works perfectly there. I have a Gigabyte B550 gaming x v2 motherboard, and the LAN adapter is a Realtek PCIe GbE Family Controller. Can anyone help me?

Select Motherboard Revision -> Select Support -> LAN Driver update
How do you know? Technical data of a device or cable do not prove its operability.
With the same CAT-7 cable or another?
Ever swapped the cable on the first PC?
I’ve already changed the cable on my main PC, didn’t work. On the other same cable and there it works.
Then the network connection in the PC has a problem. Sounds like “a” faulty contact and already only goes max. 100 Mbit/sec.
Try to set the network card statically to 1gbit/s/full.
About the device manager, right click on the network card and properties, then under “speed&duplex”.
Probably there are duplex mismatches
I have tried nothing
So this is certainly not a LAN socket that can only be 100Mbit/s?
Driver update on the client?
Does the cable possibly have a Macke?
Notification
the socket can gigabit, I have already tried to update any driver and the cable also has no macks. What is notting?
Which meter did you measure that? With another computer?
You see my username upstairs, right? What then the question?!
Notification
Oh, yeah. I thought notting was some program or something. I didn’t see your username. Sorry. Yes with another PC it works perfectly with the same cable. Could the bush be broken?
