    Please clarify your question, and provide more detail. There is no 2018.January or 18.1 release of Ubuntu, so do you mean Ubuntu 18.10? (2018.October release). Do you mean Xubuntu with ubuntu X? And providing your networking hardware details (eg. sudo lshw -C network to list-hardware of class networking) would be helpful (please don't reply in comments, edit your question & add the command & output there; using ethernet or copying text to another device where you access internet)
