Low wifi speed with opensuse leap 16

English Network/Internet
1

Good afternoon,

i have noted that my internet connexion speed is very low when i use openSUSE leap 16. My suspicion is that the wifi configuration is not optimal.
Here attached a screen shoot of a speed test.

Could you please tell me what to check and what can i do to increase my internet speed?

Thank you in advance for your help.

Regards,

Juan Pablo

Apparently that is a comparison. But you give us nothing to compare with. Do you have other speeds on other openSUSE versions, on other operating systems in the same network?
Neither do we know what type of connection, with what nominal speeds, your IP offers you.

As it is now you can not expect many useful comments.

Sorry, you are rigth.
Using mac os, i have a connexion speed of 120Mb (download) for example in wifi. Same with an old iphone.

Let me know if i need to provide more information.

Thanks

Show us the output from nmcli device wifi list and perhaps the hardware details from inxi -Nnaz as well.

Ok, so you’re using a 2.4GHz channel which is subject to interference, and contention from too many clients could also be a factor.

From the information you’ve shared, your Wi-Fi adapter is a Broadcom BCM4331, and it is currently using the bcma-based open driver. This driver generally works, but for older Broadcom chips.

Run

/usr/sbin/iw dev wlan0 link

here the output:

Ok, thanks for confirming. I don’t own such hardware, but the broadcom-wl driver (Packman repo) might be a suitable alternative for your hardware. @Sauerland Are you able to confirm this?

I have installed your proposal and the speed connection it is 10x faster. You’re absolutely right.
Thank you very much for your help.
