Hello everyone, I have been using CachyOS on my laptop for quite some time and everything works very well. The only thing I can’t explain is why with kernel 6.9.3 my speed tests seem “throttled” and on average they give a result of 750 Mbps while with the LTS 6.6.32 kernel the speed tests return average values of 1.4 Gbps. I also noticed that the broadcom modules are also loaded while I have a “Killer AX1650i” detected as “Intel® Wi-Fi 6 AX203” and the bluetooth as “Intel Corp. AX201 Bluetooth”. With the LTS 6.6.32 the firmware that is loaded is 83 while with the 6.9.3 it is 89…

Waiting for some suggestions, I thank you for your attention.

We have in the latest Kernel BBR3 patched.
Hi Ptr,
So, if I understand correct, this is also present on the default kernel?
Yes, I apologize but only now I thought of trying the default version as well. To be precise, I tried:
cachyos-v3/linux-cachyos 6.9.3-2
cachyos-v3/linux-cachyos-lts 6.6.32-1
Damn. I’ve got the same problem, i guess, and didn’t even notice.

Does changing to the cubic algorithm help?
Otherwise I think you need to create an issue at https://bugzilla.kernel.org so that the intel guys take a look on this wifi thing.
ptr1337:
algorithm “cubic”
do i have to create /etc/sysctl.conf file and edit it with:net.ipv4.tcp_available_congestion_control = cubic
or changes should work real time with:
sysctl net.ipv4.tcp_congestion_control=cubic
sudo sysctl net.ipv4.tcp_congestion_control=cubic
and then retest.
Hello,
As suggested, I reported the issue on bugzilla.kernel.org where they advised me to perform a bisect to find the offending commit. I had difficulties with Archlinux, so I had to use Debian 12 directly. I’m not sure if I did everything correctly and if I was taken into consideration.sudo iw dev.
Best regards.
