PC's Network connection problems after installing VB

[Giangibox]

Hi everybody, I've been digging into this forum but nobody run into this problem apparently:

since I've installed VM last day, the entire PC network stack [actual Host's, with not even VB running] seems unstable, mainly WiFi connectivity sometimes is lost then reconnects. I noticed this as frequently using VPN / Contivity client on my PC, from time to time the connection is suddenly broken as claims physical connection lost.
I assume the VM driver must do something at network driver level and those micro-interruptions may be the root cause.

Any clue out there ?

Thanks in advance and regards
Gianni

De-select the vbox bridge driver from the wifi connection on the Host.

WiFi adapter from Realtek may cause the problem with lost connection if VirtualBox has been started.
Just try to install the newest WLAN driver on the Host.
It should solve the problem.
