Topic: SOLVED: Can't connect to wireless or Ethernet
I installed Hyperbola on a Lenovo laptap five or six days ago.
I had to install a wifi driver (which I got here https://github.com/FreedomBen/rtl8188ce-linux-driver), but I was able to connect to both wifi and Ethernet. My wifi adaptor is a Realtek RTL8188CE. The Ethernet adaptor is a Lenovo RTL8111/8168/8411 PCI.
A few days ago, wifi stopped connecting, and ethernet stopped connecting today. I've tried connecting with both the GUI and cli versions of NetworkManager. I've been following the Arch Networking article (https://wiki.archlinux.org/index.php/Networking) but I still don't know what is wrong.
The interfaces are up, both have kernel drivers and modules in use, power saving is not enabled. The wifi adapter is always in dormant mode after I start the laptop, but nothing changes when I put it in default mode. I tried connecting with dhclient instead of dhcpcd, but nothing happened. sudo dhcpcd inteface shows "sending commands to master dhcpcd process".
I tried changing the wifi channel to auto, nothing happened (actually the Ethernet stopped connecting after I did that). The regulatory domain is set to global.
dmesg shows a lot of entries that the wifi interface "link is not ready" then a few that say "link becomes ready". The are the same entries for the Ethernet interface, but much fewer. It also shows that my wifi connection is repeatedly authenticating and then being deauthenticated "by local choice (Reason: 3=DEAUTH_LEAVING)". According to this list: https://aboutcher.co.uk/2012/07/linux-w … son-codes/
reason 3 means that means the access point went offline, which is false because I'm connecting to the same wifi network on a different laptop. There is more information about this deauth reason given here https://wiki.archlinux.org/index.php/Ne … ving_Logs, but the linked flowchart isn't loading for me, so I have not read that.
Any ideas? My wifi connection is most important right now. The wifi at least attempts to connect and then fails with error "Could not activate connection: Activation failed." For Ethernet, NetworkManager shows "Could not activate connection: Connection 'Wired connection 1' is not available on the device enp3s0 at this time" and does not try to connect.
