Wifi speed problem and connection imac 8.1

Hello there i im new in linux world , i have an old imac 2009 8.1 and i want to experiment with linux . I have install manjaro xfce in my imac , but i have speed connection problem , i have fiber up to 100mbps in my house but in speed test through this machine gives me 19mdps . I dont know whats the problem . Can anyone help me ?

@demotapa
hello
please post the output of

inxi --admin --verbosity=7 --filter --no-host --width 

first. please use the preformatted option and insert it there.

That would be for a wired (Ethernet) connection. Your wireless connection will vary depending upon factors such as the distance from the router, wifi channel, etc.

@demotapa first of all, welcome to the forum :+1:

That said before anyone can guess what the problem is, if there is any, you need to provide more info about your computer… :woman_shrugging:

So please provide the info @Olli asked for before others can break their minds over your topic. :wink:

I get 13.81 Mbps on my 2009 mbp 15m from a fiber-connected router through a single plasterboard wall, seems decent for the hardware.

Mine is:

    driver: wl

There are 2 drivers for those cards, both work. Your b43 is included. You could try installing the broadcom-wl-dkms package but I’d only do this if you have problems connecting, the connection speed will not improve, you have currently 19Mps, I have 14Mps. Be warned that installing broadcom-wl-dkms will mean clunkier updates since any kernel update will take longer because of the required dkms install. Also keep in mind that going back may not be so easy since B43 may have been blacklisted.

Not related but I’d allocate some swap with only 5.79GB ram.

According to en:users:drivers:b43 [Linux Wireless] :

PCI-ID      Supported?  Chip ID  Modes  PHY version 	Alternative 
14e4:4321   partially   BCM4321  ?      N (r2) 	

So i would also suggest you to try the broadcom-wl-dkms driver…
What does the output of the below command give you?

Good that shows you need to install the broadcom-wl proprietary drivers :+1:

Before we start to install any dkms package, we need to check if you have the needed header files for your kernel(s):

  • pamac search -i linux kernel modules
    linux60-headers                                                 6.0.8-1    core 
     Header files and scripts for building modules for Linux60
     kernel
    linux60                                                         6.0.8-1    core 
     The Linux60 kernel and modules
    linux515-headers                                                5.15.78-1  core 
     Header files and scripts for building modules for Linux515
     kernel
    linux515                                                        5.15.78-1  core 
     The Linux515 kernel and modules
    

If you get the same as on my machine, except the headers:
Then you need to install the header packages also, else you can leave out the headers.
pamac install -d linux515-headers linux60-headers dkms broadcom-wl-dkms
This will perform a “dry-run” to show you what will be installed, when you remove the “-d” it will actually install them…
After you finish installing you should reboot.

I’d stay with the LTS kernels 5.10 or 5.15 on this 2009 machine.

Try paying attention to the conversations to understand why something is suggested :wink:
(Hint, check what he already runs)

I understand your suggestion but you should make that towards his post with kernel, not my reply :wink:
