Hey, welcome to NixOS discourse!

Did you check whether your network speed independent of your internet connection is okay?

you mean, in router one device connected? then yes.
please tell me if its different

I mean if you transfer data over wifi internally between systems on the same network, what speed do you get? A controlled way to check is iperf but that requires some setup. An easy way would be just to copy a big file from your wifi machine to another machine.

I’m sorry i dont know how to use this.

No problem :slight_smile: basically in your situation you have to make a checklist and try to eliminate all potential causes of your problem. The thing that remains is most likely the cause. So the cause could be

  • some software config on your system using the wifi
  • your hardware wifi card / wifi adapter / wifi antenna
  • your router’s wifi
  • your router’s connection to the internet
  • something on the end of your internet service provider

basically you have to trail and error your way through it.

Do you have another device with 5Ghz wifi? Did you run an internet speedtest on that one?

  1. not sure which config is effecting.
  2. wifi antenna is correct.
  3. router also works with different device.
  4. able to access internet from different device with proper speed
  5. no issues from provider.

i checked with my work laptop ubuntu, 5ghz and works fine.

That’s interesting. So that would point to some potential issue with NixOS.

To confirm that, the next thing I would try is boot your NixOS machine into Fedora 39 from a USB drive and test how the wifi behaves. So same machine that has the problem, just boot into the most recent Fedora via USB flash drive and try it out.

I’m trying with nixos graphical iso latest gnome.

the comparison between NixOS and some other distro would be the key thing here. Let us know what the results are. But I might not respond today, due to time constraints.

I found the issue, but no solution for this.
My router, My PC and My Mobile are not cooperating with each other.

tested with this conditions and doesn’t work:
my router to my pc speed slow.
my router to my mobile speed slow.
That is my router to my mobile to my pc speed slow.

when it works is:
my router to any of my families mobile to my pc good speed.

I’m not sure what is causing it, but this is only way it works.
My mobile and my PC is the problem, how else can i narrow down the problem to potential fix?

12

that is strange, yes. It might be an issue with the router. Because the signal quality is good, right?

If you have that available, you might try setting up a second wireless access point and connect that to the router via RJ45 and then use that for your devices.

13

That might also works.
But can’t buy additional device, I’m thinking to get lan cable instead.
I will also switch the internet provider, stuck with 5 more months plan.
Thank you

You’re welcome! :smile: Hope you find a solution.

There was a new Linux kernel release recently to help deal with WiFi issues in 6.6.5. This caused someone I know to have really slow WiFi. I don’t know how to help beyond that but it may be somewhere to start looking. Linux 6.6.6 Released Due To WiFi Regression - Phoronix
