I run Debian 10 on a dell Optiplex 3060 and I have a problem wiith a very slow download speed from network drives. downloading a 2 GB file take about 30 minutes while uploading take only 2 minutes
I tried switching the driver (r8169 -> r8168) without improvement. I have a dual-boot with Manjaro Linux and this slow download speed is a problem only in Debian.
Here is how I mount the drive
Code: Select all
sudo mount -t cifs //nas.ads.mwn.de/ab12cde /mnt/ab12cde -o username=ab12cde,pass="my_pw",dir_mode=0777,file_mode=0777
Code: Select all
lspci |grep -i ethernet
