Not able to connect to internet when both ethernet and wifi is connected in Ubuntu 16.04

I have Ubuntu 16.04 (machine 1) and Windows 10 (machine2). I have connected the ubuntu to the wifi with IP 192.168.0.110 and I can browse internet easily.

I have to do remote C++ development on ubuntu from windows using Visual studio. I have connected the Ethernet cable between ubuntu and windows. On both the side I have set the static IP i.e. ubuntu has 192.168.0.150 and windows has 192.168.0.149. I can ping windows from ubuntu and vice versa. But when I try to browse internet on Ubuntu, its not working. If I disconnect wired connection from ubuntu, I can browse the internet fine. I don’t know what I have done wrong here due to which I am not able to connect to internet on Ubuntu.

Can anyone please suggest any idea. Thanks

How can I use Yarn to download Sharepoint Framework (SPFx) dependencies, for offline use on a VM which is not connected to the internet?

I am starting to read and learn about SharePoint Framework (SPFx).

My development environment is a VM on a machine that does not have access to the internet.

How would I go collect all the dependencies using Yarn on my laptop, and then moving them to the VM? (I can install Node.js and Yarn using their installers on the VM.)

Which yarn commands would I use to save the dependencies offline?

Unable to see USB 3.0 harddrive unless connected through USB 2.0

I recently found that I am unable to see my external usb harddrive on my Ubuntu guest VM. However, I am able to view contents on my host windows 10.

Even more peculiar is that this only happens on usb 3.0. With usb 2.0, I am able to view the external harddrive on Ubuntu guest VM.

I can confirm with a different external harddrive on usb 3.0 that I can see the disk and mount it.

I have tried running chkdsk while mounted on Windows, there were no errors reported or any issues to fix.

I have tried using different cables, Ubuntu VM still can’t see the harddrive.

While using usb 3.0:

Wifi Adapter is Not Connecting to Network, unless Laptop’s Wifi is also Connected to the Same Network

My Realtek RTL8192EU Wireless Adapter is connected on my Lenovo Yoga 730 15-IKB. I cannot use it to connect to a network without my Laptop’s Wifi to be connected to it at the same time. I have dual booted Windows 10 and Ubuntu. On Windows my Laptop Wifi cannot find my network, but because my Adapter finds it, I can connect to it and to the Internet. In Ubuntu even though my Adapter finds the network, I cannot connect to it unless my Laptop’s Wifi connects to it.

Can someone please help me.

Wifi Connected But No Internet (Ubuntu 18.04)

So I have a Lenovo computer (with Ubuntu 18.04) and I just got a wifi adapter. I can connect to it just fine (it has full bars and it says “Connected”), however; when I try to go to any website, it immediately says “No internet” (with the dinosaur, as I use Google Chrome). I tried multiple things to fix it (looked up YouTube videos) but nothing worked. I tried to read other things on this forum but I’m very new to Ubuntu/Linux (used Windows 10 for my whole life) so I have no clue what to do.

If anyone can assist me in fixing this issue, it’ll be gladly appreciated. If you do have a solution, please note that I’m new to this (pictures and/or easy step-by-step guides will be helpful 🙂

Thank you again!
