sorry in advance because not sure its an easy problem to explain and I am not a Linux expert at all[/FONT] I built few weeks ago a new rig, dual OS with Ubuntu 16.4LTS.Mobo is an ASROCK B350 PRO4 and comes with a Realtek RTL8111GR Lan. some time ago, I bought a USB Wifi dongle to connect my PC to my Chromecast devices, the dongle uses also a REALTEK chipset but wasn't recognized so I followed this tutorial to get the drivers to work and card to be recognized, it was quite painful but it worked in the end How do I get a Realtek RTL8723BE wireless card to work? now since some recent Ubuntu software update, after a normal boot, there is no LAN and Wifi access anymore on my desktop, networking as a whole just dont work I have to launch a session from a generic image in the bootloader, one at the time I had installed the Wifi dongle, and both LAN and Wifi work as they should now Ubuntu is creating generic images since then and those also exhibit the same problem as the normal boot, no Networking at all any idea about what would have happened and how to troubleshoot this? thanks so much

Hi, welcome to the fora. We get many posts from people running old software on new hardware, like yours. As a first step to prevent trouble in general I suggest that you begin with a fresh install of 17.10. From 18.04 onwards you can probably take the LTS track.

thank you, I appreciate the welcome and reply but what puzzles me is that network connection both lan and wifi works on a previous image of my 16.04LTS so considering I have installed quite few apps, media streaming softwares and all that on top of desktop customization,I would like to avoid ditching all that all that whenever possible
What is the newest kernel you have? Post results from terminal for Code: ls /lib/modules

4.10.0-37-generic 4.10.0-40-generic 4.4.0-97-generic 4.10.0-38-generic 4.4.0-101-generic 4.4.0-98-generic currently logged in from 4.10.0-37-generic image where lan&wifi work anything above network doesnt work
I have to correct myself, both 4.4.0-101-generic 4.4.0-98-generic dont have network working either, same as recent ones any idea how I could troubleshoot this issue? any command to verify networking feature is active or not for example? reinstall lan card and wifi usb dongle drivers entirely maybe? Its set "enabled"in network settings but as I mentioned, no lan or wifi access whatsoever why only this particular image 4.10.0-37-generic is working is really puzzling me. thanks in advance

Post results for Code: lsusb; dkms status I am still puzzled on how that RTL8723BE answer helped any as that is a PCI wifi not USB
lsusb; dkms status
to avoid a confusion, the link I sent about this RTL8723BE was a method I used to install my USB wifi dongle nothing else this is what returns from both commands you asked me to run Bus 004 Device 001:ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 003:ID 05e3:0608 Genesys Logic, Inc.

thank you again for your help. just a sanity check before I proceed. It seems my ASROCK PRO4 Mobo LAN chipset is RTL8111GR and my WIFI USB one is as listed below RTl8811AU(sorry about Japanese language, I live in Japan so I bought it here) but you are mentioning RTL8812AU. Does that mean both drivers are compatible? 仕様 チップ：RTL8811AU チャンネル： 2.4GHz帯 :1~13ch 5GHz帯 : 13/36/40/44/48/149/153/157/161/165ch 設定方式：WPS (ソフト / ボタン方式) 外形寸法 (幅×高さ) 約12.5ｍｍ × 約140ｍｍ 質量：約50g
