I installed Ubuntu 22.10 after 22.04.
In version 22.04 I had an awful experience with the internet connection.
The problem may be caused by the Kernel version used by 22.04, and I had to upgrade the Kernel version from 5.15 to 5.17(there are many recommendations about it in forums). But, I decided to install ubuntu 22.10, which uses kernel 5.19. The problem has remained.
For example, I got OpenJDK through the terminal by 6 kB/s! I even used my mobile internet, but I got the same result. I had to download Eclipse IDE on my mobile and transfer it to my computer to avoid waiting for 23 hours to download! There is nothing left that I have not done.
Please help me!
The things I have done until now :
- manipulating /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and change wifi.powersave from 3 to 2
- upgrading the kernel version from 5.15 to 5.19
- manipulating /etc/sysctl.conf and add following commands to the end of file :
net.core.rmem_default = 32768
net.core.rmem_max = 32768
net.core.wmem_default = 32768
net.core.wmem_max = 32768
net.ipv4.tcp_wmem = 4096 32768 32768
net.ipv4.tcp_rmem = 4096 32768 32768
net.ipv4.tcp_mem = 32768 32768 32768
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_ecn = 0
net.ipv4.route.flush = 1
