I have virtualbox 4.3.20 (win 7 x64) and debian 7.7 stable wheezy installed on my computer. My network settings for VB are: Attached to bridged adapter, promiscous mode deny My problems is that networking in problematic. When I start downloading (apt-get or else) it halts. Sometimes it continues and sometimes connection fails.
It works for a some seconds and then problems start. Network is idle for 5-20 sec and then it continues.
