4.3.24 on Windows 7 x64 host - messed up networking

[lewekleonek]

I am currently running 4.3.20 on my machine after a quick roll-back from 4.3.24 update that messed up my networking.

4.3.20 is "rock solid". It's been a fine and stable build for me.

The minute I have upgraded to 4.3.24 the networking went out the window. The bridged network drivers installed by virtualbox seem to be messing up the whole network - the drivers cannot be loaded with code error 31 + the physical NIC driver cannot connect to network anymore.

I did try to update the driver by pointing it to the 4.3.24 install directory\drivers... to no avail.
I did try to reboot the host machine - no luck.

Nothing conclusive shows up in the Windows Event Viewer logs that would shed some light as to why the drivers are messed up.

What's worse - the networking just drops all together i.e. host is without connection.

The minute I have rolled back to 4.3.20 everything starts working again.

Some specs:
CPU: i5-4670 CPU
RAM: 32 GB
M/B: ASUS GRYPHON Z87
NIC: Intel(R) Ethernet Connection I217-V

Windows 7 x64 SP1 with the latest updates and drivers

4.3.26 is out and things are still messed up with bridged networking adapters.
What gives?

Never mind... figured this one out myself.
I've unplugged Bluetooth USB dongle and un-installed the Toshiba Bluetooth stack.

Seems like another conflict that the dev team needs to figure out.
