WiFi problem at user logon

[Edward Yang]

Starting from version 10.0.8, I have a very weird problem with WiFi connection at logon. The connection appears good as normal, but actually it is not and no internet connections can be made.

I have to disconnect and reconnect to get network working. This happens verytime I logon my account - with one exception.

The exception is - Everyday in the morning I power on my computer, it works as normal; but after that during the day, even a cold reboot would not work.

My system is Windows 10 (build 10586).

You mean VirtualBox 5.0.8, not 10.0.8, right? When you are talking about your WiFi connection problems at logon, how does this problem interact with VirtualBox? I mean, do you logon in your VirtualBox guest? Please describe the problem a bit more in detail.

[Edward Yang]

Yes, I meant this problem started at version 5.0.8.

At user logon, I do nothing. WiFi network shows normal, but actually no internet connections can be made.

So why do you think this is a VirtualBox problem? Does it not happen if you uninstall VirtualBox? Also, did you already try VirtualBox 5.0.12?

[Edward Yang]

Yes, I am 100% sure it's caused by VB because the problem will be gone if I uninstall VB.

Still getting this problem with 5.0.14.

You still haven't described the exact scenario.

but actually it is not and no internet connections can be made.

Just to be sure, do you mean host or guest here?

I power on my computer, it works as normal; but after that

What exactly does "after that" mean? Do you suspend your computer to move to a different network and it then doesn't work when you resume it? Does it just spontaneously lose connectivity? Do you have a VirtualBox VM running when either of that happens? Does that VM uses bridged attachment to your wifi adapter? Etc, etc...

during the day, even a cold reboot would not work.

Does that mean that you reboot your computer, log on, and the wifi network has no actual connectivity so you "have to disconnect and reconnect to get network working"?

[Edward Yang]

Let me clarify.

In the morning, I power on my (physical) computer and log on my account (Windows 10 Pro). After logon, I do nothing because this problem is not related to any VM sessions. The WiFi icon in systray appears good, but it's not. I have to disconnect and then re-connect to get WiFi working as normal.

If I reboot my (physical) computer during the day, after I log on WiFi icon would appear problematic with a small yellow alert icon. Then again I have to disconnect and re-connect to get it working.

To be more clear, I have confirmed this weird problem is caused by VB installation because after I uninstall VB, WiFi works as normal (just like what it does for past many years).
