SER5 Linux Network Card Has "Pause" Issues At 2500 Mbps

Hi, I have 2 of your SER5 computers

Model: SER5 MAX-L-321TBEJ0W64PRO-DP/XA

I have installed Debian 13.3 on both and the WIFI works PERFECTLY!

BUT… the 2.5GB port is not recognized by Debian so I have to install the “realtek-r8125-dkms” from GitHub:

git clone https://github.com/awesometic/realtek-r8125-dkms.git
./dkms-install.sh

AND… then I find it has “traffic pause” issues at 2500 Mbps.

If I use “/usr/sbin/ethtool -s eno1 speed 1000 duplex full autoneg on” then there are no “pauses” and all SSH and DIR/SAMBA and HTTPS traffic runs smoothly.

I was going to see if you had a BIOS update but when I try to surf to:

https://dr.bee-link.cn/?dir=uploads%2FSER

I get an error:

Secure Connection Failed
An error occurred during a connection to dr.bee-link.cn. SSL received a record that exceeded the maximum permissible length.
Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Do you have another website with SER5 BIOS ???

Oh, I see that it is using the r8169 driver instead:

lspci -k

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 0c)
DeviceName: Onboard LAN Brodcom
Subsystem: Realtek Semiconductor Co., Ltd. Device 0123
Kernel driver in use: r8169
Kernel modules: r8169

Ok, I will find the Realtek driver, and blacklist the r8169…

You can close this ticket.
