    Re: Have NO internet! Can not get new wifi adapter [supposedly Linux-friendly] to wor

    I'm sorry to have to report a BIG NEW problem. Everything was working well for several days. Today it was working and on all day....I took a nap and then came back to the computer [not having been turned off] and noticed there was NO internet. I ran some of the diagnostics and some of the 'fixes' and 'repair' methods listed in this thread. Nothing worked. The computer said my wifi device was down. I rebooted and remembered that a new kernel was installed this morning, so I tried two older kernels. Nothing helped. Now all of my hardware-based network devices are UNCLAIMED. Please help! I'm really confused at how it went from just fine to all messed up again. Today, I was doing mostly word-processing while also sometimes doing internet searches and connecting to various sites.....somewhere in the later part of the day, something went terribly wrong. I was NOT using terminal until AFTER I noticed my wifi device was down.

    Code:
     $ sudo lshw -C network; lsb_release -a; uname -a; sudo iwlist scan | egrep 'chan | sid'

    Re: Have NO internet! Can not get new wifi adapter [supposedly Linux-friendly] to wor

    OK, I ran

    Code:
    sudo sed -i 's/blacklist r8169/#blacklist r8169/' /etc/modprobe.d/blacklist.conf
    again, rebooted [had forgotten that was necessary when I panicked], and all are claimed again and I have internet again.
    My question, however, is why did that happen and if it was the addition of a new kernel? They come regularly. Will I have to do this each time I get and install a new one?...and I still have to go to terminal each time
    and tell the computer to look for the repeater's SSID to connect [sometimes more than just at the beginning of a session] - as I have NO network manager. It is shown as installed, but I can not find it nor get it to open using terminal..... So, I have a 'solution', but not a good nor easy one. Thanks.

    I am not familiar with that DE you are using so I cannot help much with network manager. The blacklist was the result of commands you ran back early in this topic and somehow the replacement driver disappeared and the kernel module was still blacklisted resulting in unclaimed status
