Hello, I don't have even any network connection with the latest kernel (4.*15*.0-24-generic) . So what I am doing >> logging in the older kernel (4.*13*.0-45-generic) and booting the Ubuntu 16.04 then only it is working. I have tried several time the "Software and updates" from the menu but the same situation. Do someone have any software that I can download from the older kernel and then login with the new kernel to install it. Because the on-line method won't work from the new kernel system as because there is not Internet connectivity (meaning neither wired LAN or WIFI ).. For reference here is the device details of *my *HP laptop n109tu red model ------------------------------------ *-network description: Wireless interface product: *BCM43142 802.11b/g/n* *-network description: Ethernet interface product: RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller vendor: Realtek Semiconductor Co., Ltd. ---------------------------------------- Thanks for your help, Rajdeep Majumder On Sun, Jul 22, 2018 at 1:12 PM, luislay
