I am having difficulty with my internet speed. It worked fine until four days ago. Now my average speed is ~75KiB/s. It is a hotspot connected through my phone. The phones' speed is fine.



There are many posts, however I have not been able to convert their suggestions to resolving my issue. So far I have succeeded in collecting a list of various CLI outputs.



If anyone is willing to help I would be appreciative.

    Please issue the following command: echo "blacklist ideapad_wlan" | sudo tee -a /etc/modprobe.d/blacklist.conf and reboot your computer. Issuesudo systemctl restart systemd-modules-load.service. Now connect your Wi-Fi to internet and conduct some speed tests. Please report the result.

  • Thanks for the response. I ran the first command, shut down, ran the second command, and got: Latency Test Error Could not connect to the test server. A firewall could be blocking the connection or the server might be having some issues. It is still sitting at ~75.

  • Please edit /etc/modprobe.d/blacklist.conf and change ideapad_wlan toideapad_laptop and save the file. Now reboot your computer. Issue sudo systemctl restart systemd-modules-load.service and observe the output. If no output, then the blacklisting was successful. Now connect your Wi-Fi to internet and conduct some speed tests. Please report the result. Please post the output of the command rfkill.

  • The blacklisting was successful: blacklist ideapad_wlan. At least to that degree. Should I follow your current suggestion minus the file edit? To note, I did the first suggestion twice to attempt to connect before running systemctl and it did connect to the internet. So, maybe the blacklist did not work?

    – DMon
    Apr 17 at 15:29












  • Let me understand you. Now you are referring to my first comment. What was the output of the command sudo systemctl restart systemd-modules-load.service after blacklisting ideapad_wlan? Can you use Bluetooth now? Is it working?

I am having difficulty with my internet speed. It worked fine until four days ago. Now my average speed is ~75KiB/s. It is a hotspot connected through my phone. The phones' speed is fine.



There are many posts, however I have not been able to convert their suggestions to resolving my issue. So far I have succeeded in collecting a list of various CLI outputs.



If anyone is willing to help I would be appreciative.

    Please issue the following command: echo "blacklist ideapad_wlan" | sudo tee -a /etc/modprobe.d/blacklist.conf and reboot your computer. Issuesudo systemctl restart systemd-modules-load.service. Now connect your Wi-Fi to internet and conduct some speed tests. Please report the result.

  • Thanks for the response. I ran the first command, shut down, ran the second command, and got: Latency Test Error Could not connect to the test server. A firewall could be blocking the connection or the server might be having some issues. It is still sitting at ~75.

    Apr 17 at 14:08












  • Please edit /etc/modprobe.d/blacklist.conf and change ideapad_wlan toideapad_laptop and save the file. Now reboot your computer. Issue sudo systemctl restart systemd-modules-load.service and observe the output. If no output, then the blacklisting was successful. Now connect your Wi-Fi to internet and conduct some speed tests. Please report the result. Please post the output of the command rfkill.

    Apr 17 at 15:23












  • The blacklisting was successful: blacklist ideapad_wlan. At least to that degree. Should I follow your current suggestion minus the file edit? To note, I did the first suggestion twice to attempt to connect before running systemctl and it did connect to the internet. So, maybe the blacklist did not work?

  • Let me understand you. Now you are referring to my first comment. What was the output of the command sudo systemctl restart systemd-modules-load.service after blacklisting ideapad_wlan? Can you use Bluetooth now? Is it working?
