computer wakes up from sleep mode

[Maddl]

Hello,

My system:

Desktop PC, Intel Core i7-14700, Killer E3100G 2.5 Gigabit Ethernet Controller, BIOS version Dell Inc. 2.11.0, Windows 11

My problem:

The PC wakes up from sleep mode by itself (the hibernate mode works, here the PC does not wake up). The peripheral devices that are connected via USB are definitely not the problem. My assumption is that the network adapter is the cause. If I deactivate it in the device manager, the problem disappears.

What I have tried so far:

1. device manager > network adapter Killer E3100 > power management > allow this device to wake the computer > disabled
2. device manager > Network Adapter Killer E3100 > Advanced > Wake on Magic Packet > disabled
3. device manager > Network Adapter Killer E3100 > Advanced > Wake on pattern match > disabled
4. device manager > Network adapter Killer E3100 > Advanced > Shut down Wake-On-Lan > disabled

None of these measures were successful. There are also no options in the BIOS power options that could help me (see attachment). I don't know what else I can try. This is annoying. Can you please help me?

Many thanks in advance
