Slow wifi and ethernet on manjaro kde

Support Network
1

I’m running manjaro KDE on linux 5.15.25 and both my wifi and ethernet connections are rather slow. I have a 70 MB/s connection and my top speed is just 10 MB/s. I have tried this suggestions without any luck.

Here’s my inxi -v7azy output:

I have problems disabling mac addres randomization, since the boot promtI get an NetworkManager error and I have to delete wifi.scan-rand-mac-address=no. Here’s the log and the service status

I fixed it now, I forgot to add the [device] part (heh), but I am still getting 10 MB/s speeds.

Posting a single word or useless message (bumping) to attract attention to your thread is not allowed. Do your own research, continue to troubleshoot, post the results, and be patient with the community. If people are reading your thread without answering or offering help, you may try supplying more details, or ask to be pointed in the right direction. Often, the reason for posts remaining unanswered is due in large part to the sparse details in the original post itself, or, the obvious availability of solutions in the wiki, on the forum or on the web, and the community’s unwillingness to point out the obvious.
