Firefox wifi connection


I have a laptop running Windows 7 pro., I installed Oracle VM VirtualBox Version 5.0.12 and created 2 linux virtual machines (Centos 7). When I log onto my VMs and try to connect to the web via Firefox web browser I get an error message "Server Not Found". I know my wireless card is working because from my Windows OS I have no problems connect to my home wifi network and connecting to the web via Chrome wed browser. How to I correct this issue, I need my VM to connect to the web so that I can update, and install programs.

Can you post the output of "/sbin/ifconfig -a" from one of the Linux VMs? Also, you'll need to provide some details about how you set up networking in VirtualBox (i.e. are you using NAT, bridged or host only). The default is NAT, but you should confirm what you have. I've noticed with CentOS 6 at least, some minimal installs won't start up the DHCP client daemon automatically on the first Ethernet adapter. I'm not sure if that holds in 7, but it may be something to check via systemctl.

In the Settings-->Network Settings for the Virtual Machines, what type of of networking is selected: NAT, Host Only, Bridged, or something else?

In my brief experience with Windows as VBox host, network bridge is quit flaky. Just use NAT. And don't forget to tick the 'Cable connected' box.

Using a bridged connection, I've found that sometimes the default "Adapter Type" (see the "Advanced" item on the Network Adapter dialog) is not always the best choice. If the default adapter is not working, try cycling through the other available adapters. It could be that one of them will work. Admittedly, this is rare, but I have encountered it a couple of times.

To build on what c0wb0y said, test first with a NAT connection.

FWIW, I run VBox on a Windows host and using a bridged adapter (usually to wireless interface) without any issues. The image you shared shows that eth0 has 192.168.122.252 assigned. Ideally, you should show the guest addressing and routing and demonstrate that you can reach the gateway and well known internet address...

Code:
ip add
Code:
ip route
Then ping the gateway eg assuming 192.168.1.1
Code:
ping 192.168.1.1
Code:
ping 8.8.8.8
Code:
ping google.com
