Earlier, I was using multiple instances of Virtual Machines running Linux Ubuntu 14.04 on VirtualBox. They were working fine, with internet connectivity, etc. However, I then created a new Virtual Machine with the same settings, and now all of a sudden, all three of my virtual machines cannot connect to the internet. Currently, the network settings are at Bridged Adapter. The internet DOES work when I use NAT, but I need to use the Bridged Adapter setting for the project I am working on.

I have tried uninstalling and reinstalling virtualbox, as well as uninstalling and reinstalling the VirtualBox Bridged Networking Driver, as well as turning off and turning on my host computer. Now I am completely out of ideas and it has been putting my work to a standstill. If you have any ideas on how to fix this problem, it would be appreciated.

  • Why do you need to use Bridged? In the past (before the NAT option was available) I found almost randomly that Bridged would not work (or just stop working) and I've have to switch to something else. – Bernmeister Jul 29 '14 at 23:25
  • @Bernmeister yes that's exactly what's happening! I want to use Bridged because it provides me two different IP addresses on the two machines, which is what I need. If there is an alternative (more reliable) method to doing so, do you have any suggestions? – jj172 Jul 29 '14 at 23:38

    @Bernmeister yes, I was using two virtual machines to get unique ip addresses for each one. Anyways, my problem has been fixed now, it was not a fault on my end but rather on our work's network. Thanks for your help though! – jj172 Jul 30 '14 at 16:35

    Voting to close because problem was elsewhere and solved. Question has no use to others. – zwets Aug 28 '15 at 7:24

    Reviewers: the answer clearly states that this problem had a completely unreproducible cause - will not help anyone in the future. – guntbert Dec 8 '16 at 18:35

In fact, the problem was not with my computer, but with the network I was working with at work. Sorry for the confusion, but after people fixed the screwy network, it solved my issue. Thanks!
