    New Install Packet Loss On Home Network

    Hello,

    I recently installed Ubuntu 16.04 on a old HP 2000 notebook.

    Unfortunately, now the wifi does not work on the laptop, but only over my home network. I used it over wifi at my library and it worked fine. (0% packet loss when pinging google, web browsing worked fine.) But on my home network I get 50-80% packet loss when pinging google or the router.

    I don't think the issue is my router because my windows computer and android phone both connect fine (0% packet loss to google over windows). Another thing that complicates my trouble shooting is that I don't have easy access to the physical router, since I get my wifi from a guy in the dorm next to mine.

    I also am super new to linux, this computer is the first one I've downloaded it on. So I apologize in advance if anything I've said is unclear or I've made obvious mistakes.

    Lets try
    Code:
    echo "options rt2800pci nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800pci.conf
    sudo modprobe -rfv rt2800pci
    sudo modprobe -v rt2800pci
    sudo iwconfig wlo1 power off

    Now it get's 100% packet loss and says destination host unreachable. It still claims to be connected to my wifi network though.

    Thank you for the continued help
    (EDIT) misspelled a word

    Re: New Install Packet Loss On Home Network

    I installed ubuntu 18.04 from usb, this fixed whatever issue was occurring in ubuntu 16.08 on the device. It is now connecting just fine to the wifi with 0% packet loss.
