Can't connect to ethernet connection on Realtek RTL8111/8168/8411

ca flag

This morning I woke up and my pc wasn't using the nvidia driver, (usually this happens after a kernel update, I'm not sure whether the update actually happened). Since the nvidia driver were already broke, I decided to run all the updates. I also tried to switch to nvidia drivers again, so I went into software & updates, additional drivers and selected the nvidia ones. After getting an error I decided to reboot anyway because the update required it.

After rebooting, my Ethernet connection wasn't working anymore. I tried to run the pc with the previous kernel, but the system doesn't boot up and shows:

rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100)
rtl_rxtx_empty_cond == 0 (loop: 42, delay: 100)
...

some log that may be useful:

Thank you and let me know if something else may be useful. I tried all the standard stuff like rebooting both pc and modem, deleting connection etc

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
