Solved Internet Connectivity Issues (Default Gateway Missing)

[chev65]

In this case it's most likely that the virtual box is actually causing the issue. I've seen this happen before quite a few times although I'm not entirely sure what the virtual box Ethernet connection is being used for?

As a test I would enable DHCP on the Ethernet connection then uninstall V box and test for reliable connectivity over a time period.

It may also be worth typing the gateway IP of 192.168.0.1 into the IPv4 static settings for the Default Gateway of the Ethernet connection since it doesn't seem to be picking it up for some reason. This may be because the static IP info isn't entered correctly.

Try using a different version of Virtual box if the test proves correct.

The connectivity issues were happening before I installed VB, but I will change the IPv4 first thing and report back in a day or two.

...I'm not entirely sure what the virtual box Ethernet connection is being used for?....

Phluff might want to read this and then decide if that VirtualBox (VB) feature should ever be installed.

One can have the VB VMs be on their own network - isolated (via NAT) from the network that the host computer is using.

One can have the VB VMs join (via bridging) the network that the host computer is using.

But - the Host-Only network works when there is no real network available (e.g. on a plane). It acts like a virtual router... handing out IP addresses to the HOST computer and each VB VM. That way, you can still test various network/computer/server setups in a self contained environment - without a physical network.

I personally don't install the Host-Only feature (and one other feature):



Unfortunately, you must uninstall VB (keeping the VM files/settings) and then reinstall VB to change the features that are installed. If you have need of the Host-Only feature, then consider disabling that adapter until it is needed.



Phluff,
It looks like you had OpenDNS set at one time. After you figure out what is going on with your connectivity, I would go back to using OpenDNS.

You might want to setup a constant ping to your router, your modem and to Google...

...then when you get disconnected, you can quickly tell which leg of the network is broken.

Thanks Uni, I'm now running those .bat. If anything happens in the next day or so, I will have an account of it.

I have to ask, is there a way to have it automatically write to a .txt file with ping errors?

You can redirect the output of the ping to a text file, but then you lose the visual indication that things have gone haywire.

ping 192.168.0.1 -t > %UserProfile%\desktop\192.168.0.1.txt

You can minimize the ping windows or move them to where they are almost off screen. You only need to bring them up (from being minimized) when you lose connectivity. Or, you can wait until you lose your connection to even start them.

Thanks Uni. This will help when things go bad and I need some proof.

I can promise you that having the V Box installed will not help with any trouble shooting and it's still by far the most likely cause of the problem regardless of when it was installed so please spare the reply of it was not working before the V box was installed.

Or I should ask, why in the heck you would install a some sort of V box when you already don't have a reliable connection? You may not realize this but you are tossing the baby out with the bath water in this case.

I've seen these V box set ups cause the same problem on multiple occasions and so have helped fix the problem on those occasions where the OP didn't have a clue on what the problem might be.

Yes I know what they are for UNI, I just can't believe someone is trying to fix a networking problem where there is a VM attached to their network stack, utterly ridiculous.

It's simple, remove the V box completely from the system, run CCleaner to remove the registry entries, turn DHCP back on and reset the entire network stack using the link below. If you are still having the gateway issue then type the default gateway IP into the IPv4 settings for Default Gateway.
