Since I've upgraded from Windows 8.1 Pro to Windows 10, my connection randomly lags. In a minute I'm receiving 13Mb by wifi, in the next I only get 1Mb or less. I've switched off the shared updates and reinstalled wifi drivers, but the problem persists. Any ideas?

Navigate to:

Control Panel > Device Manger > Networks adapter > Right click on Wireless LAN network > Proprieties > Advanced

Now make sure your options like this

• Bandwidth capability > 11b/g or 11b/g/n
• Fragmentation Threshold > 2346
• Power Output > 100%
• 802.11n > Auto 'NOT MIXED'
• Antenna Diversity > Auto
• Compatibility Mode > Higher Performance
• ARB Ofloud > Enable
• BSS > Auto

I just upgraded my laptop from Windows 7 to Windows 10 and found that I am unable to start Virtualbox VMs configured with a bridged adapter.

See the configuration below:

First of all you have to create a VirtualBox Host-Only Ethernet adapter

In Virtualbox :

• Go to File > PreferencesOn the Network tab select Host only Networks click on 'add a Host-only adapter' give it a name by default it is 'VirtualBox Host-Only Ethernet adapter'

In Windows :

• go to Network connections on Windows and highlight both the real adapter and the new virtual ethernet adapter that you just created.
• Right click and select 'Bridge Connections', it's going to create a network bridge in Windows.

Now configure your VM :

• in the Network part you can activate a new adapter and then select Attached to Host only adapter
• Choose the VirtualBox Host-Only Ethernet adapter you have just created

You can now configure your static IP Address by modifying /etc/network/interfaces :

You can now restart eth0 by doing :

Some wireless adapters don't work

My Windows 10 machine was automagically updated today. Looks like the 'Windows 10 Anniversary update' When I restarted Virtualbox my server with a bridged adapter showed same as OP. I tried rerunning the VirtualBox installer (it did a Repair) - that did not fix the issue. I tried running the installer again as Admin (it did a Repair) - that did not fix. I ran the installer and selected UnInstall, then ran it again to Install. And the Network adapter settings looked good. Server started and connected to my network as usual. Whew.Hope this helps someone.

Install the latest Virtual box 5.x and this issue will be resolved.

This is how I mananged to fix this problem:

Enable 'Windows 8' compatibility for VirtualBox executable:right-click on VirtualBox shortcut>Properties: in Properties dialog box: switch to 'Compatibility' tab, under 'Compatibility mode' section, select the check box next to: 'Run this program in compatibility mode', make sure 'Windows 8' is selected in combo box. click Ok, run VirtualBox again!(it's not needed to run as Administrator)

p.s.: It seems that VirtualBox doesn't yet fully support Windows 10, so some features might not work properly on some computers Cm2 crack tool.

Uninstall then run the setup program again but this time as Administrator. Make sure the VB bridge driver is selected during installation.

From Reddit:

I can't see the original source in this thread, although I would like to.

I am using these instructions with a laptop that upgraded from windows 8 to windows 10. I have to repeat the last instructions after rebooting.

I have test an get solution for my self and want to share my solution. - Host Only worked - Bridge Adapter worked

My Configuration is - Surface Pro 1 - Clean install Windows 10 x64 build 10130 - VirtualBox-5.0.0_RC1-100731-Win.exe

(this is my opinion but not tested on how to remove previous version by install VirtualBox-5.0.0_RC1-100731-Win.exe with select all function to install its will fault and rollback all, then its same as uninstall)

Install Step - Right Click on VirtualBox-5.0.0_RC1-100731-Win.exe and select 'Run as Administrator' - 'Unselect' option bridge network

• next until finish

• Open 'Device Manager', you can use search bar to get this, under 'Network adapters' then Right Click 'VirtualBox Host-Only Ethernet Adapter' select 'Update Driver Software' select 'Search automactic' wait until its finish

• Open 'Network Connections', you can use search bar to get this, at here you should find VirtualBox Host-Only Ethernet Adapter
• Open 'CMD', you can use search bar to get this, Right Click and Select Run as Administrator
• cd to your install path and run command 'VirtualBox-5.0.0_RC1-100731-Win.exe -extract' its will return pop-up tell where is extracted folder
• in extracted folder extract 'VirtualBox-5.0.0_RC1-r100731-MultiArch_amd64.msi' by 7-Zip or any similar
• in msi extracted folder rename all files by remove file_ in front of them
• copy 'VBoxNetFltNobj.sys' and 'VBoxNetFlt.sys' to C:WindowsSystem32
• Open 'CMD', you can use search bar to get this, Right Click and Select Run as Administrator run command 'regsvr32.exe /s VBoxNetFltNobj.sys' run command 'regsvr32.exe /s VBoxNetFlt.sys'
• Open 'Network Connections', you can use search bar to get this, Right Click on any real network adapter select Properties select Install select Service select 'Have Disk' and browse to 'VBoxDrv.inf' select 'VirtualBox NDIS6 Bridged Networking Driver' after finish install you should see its avaliable in this connection

• On Start Menu Right Click on 'Orcle VM VirtualBox' select open file location

• Right Click on Shortcut then select properties on tab 'Compatibility' checked 'Run this Program as Administrator'

!!! this very important to run application with adminstrator if not you will lose host-only network adapter

• Open 'Virtual Box' select file > preference select network then select Host On Network select edit change ip to 192.168.56.1 and netmask to 255.255.255.0
• Now you can use both host-only and bridge network on your guest

I think reason why normal installation was error is about Administrator access level when regis service and run application

Sorry for my bad english and this is so long procedure

Hope this will work for you too. ^_^!

Install 'vbox-ssl-cacertificate.crt' certificate from %userprofile%.virtualbox and then reboot. If you don't have .virtualbox folder - launch 'Oracle VM VirtualBox' once and this folder will appear.

I had this issue not only on my machine but on many hosts, and this certificate fixed the issue. I figured it out by chance, because nowhere said about this certificate -_-

I solved it with similar way to @Khalil's but I attched to 'Bridged Adapter' instead of 'Host-only Adapter'. Here is more detail with screenshots.

My very simple solution that worked: select another networkcard!

1. Make sure your guest is shut down
2. Goto the guest Settings > Network > Adavanced
3. Change the Adapter Type to another adapter.
4. Start your guest and check if you got a decent IP for your network.

If it doesn't work, repeat steps and try yet another network adapter. The very basic PCnet adapters have a high succes-rate.

Good luck.

I faced the same problem today after updating the Virtual Box.Got resolved by uninstalling Virtual Box and moving back to old version V5.2.8

Go to your net card. Go to properties and then 'Add service', which? This: VirtualBox NDIS6 Bridged Networking Driver

Reopen Virtual Box

WINDOWS FIX: Ive' Fixed it by downloading a new VMbox installer from the Official Website Here.

• Just run the installer and install it to override your current VMBox version,that should fix it.

Dont worry about your VM's they will not disappear if you override your current installation.

NOTE: If you already have the latest version, you need to export all your VM's, unninstall your current VMBox and install it from new installer.

As of now (5.2.20) bug is fixed. The only action required is to download the latest version and bridge mod should function normally.

In Case some one is looking and none of the above resolves your issue :https://forums.virtualbox.org/viewtopic.php?f=6&t=90650&p=434965#p434965

placing the WIFI as the first adapter [MTDesktop, AllowALL] and the LAN WIRED [MTServer,AllowAll] as the second adapter.In the Guest machine I disable the First Adapter in Adapter Settings. I can then ping internal, external whatever.

i had same problem.i updated to new version of VirtualBox 5.2.26and checked to make sure Bridge Adapter was enabled in the installation process now is working
