Hello JorgeB, Thank you very much for your prompt response.

Hello! I have detected that the download speed of my network card has been limited to 20MB/s, when normally it should be 100MB/s. I detected it when I had Unraid 6.12.5 and decided to upgrade to Unraid 6.12.6, however I detected this in patch note: Release-notes/6.12.6 "Problems due to Realtek network cards Stock Realtek drivers in the latest Linux kernels are causing network and stability issues. If you are having issues and Tools > System Devices shows that you have a Realtek ethernet controller, grab the part number shown and search Community Apps to see if there is a Realtek driver plugin for that device. For more information, see the support page for Realtek driver plugins." Things I've done to try to fix the problem: I have updated the version of Unraid from 6.12.5 to 6.12.6 I have changed the network cable with a new one. I have installed the "RTL8168(B)/RTL8111(B) PCI Drivers" (RTL8168 Drivers) plugin, as recommended in the patch notes. I have restarted my router, in case it is a related problem. My others computers can download at 100MB/s without problems. Unraid Version: 6.12.6 2023-12-01 NIC: root@Tower:~# lspci | grep -i Realtek 07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15) Driver version: root@Tower:~# ethtool -i eth0 driver: r8168 version: 8.052.01-NAPI firmware-version: expansion-rom-version: bus-info: 0000:07:00.0 supports-statistics: yes supports-test: no supports-eeprom-access: no supports-register-dump: yes supports-priv-flags: no Network interface information: root@Tower:~# ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Link partner advertised pause frame use: No Link partner advertised auto-negotiation: Yes Link partner advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Auto-negotiation: on Port: Twisted Pair PHYAD: 0 Transceiver: internal MDI-X: Unknown Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) drv probe ifdown ifup Link detected: yes Conclusion and hypothesis: I think we will all agree that it is a problem with the NIC driver. As I have checked on the official Realtek website, the latest published version is the one I already have installed: Unix (Linux) Description: GBE Ethernet LINUX driver r8168 for kernel up to 5.19 Version: 8.052.01 Update Time: 2023/09/28 Realtek PCIe FE / GBE / 2.5G / 5G Ethernet Family Controller Software My hypothesis is that there is a problem with the driver and they have not yet published a fix for it. Does it fit you? Anyone else in my situation? Thank you and best regards, ZanoX
