Per your previous post on this subject
viewtopic.php?f=6&t=98012 You apparently successfully switched to NDIS5.
Switching NDIS is extremely likely not your problem. You should switch back. If I remember right, switching from NDIS 6 to 5 was only a thing at some stages between Virtualbox and some version of Windows (possibly 7, along with Virtualbox 5.0.smallnumbers, see
viewtopic.php?f=6&t=70052) due to some glitches people were getting and the downgrade fixed the problem. That issue is old and no longer needs to be implemented. You're on 8.1, switch back to NDIS6.
Next time best to ask about your problem, not your solution to the problem. We were all stuck in an
"XY problem" over this NDIS# thing.
VirtualBox-5.0.10
You're using a very old outdated version of Virtualbox, which apparently did have some NDIS problems with Windows 7. But you're on 8.1. Upgrade to at least a higher last number in 5.2.x or 6.0.x, if not go up to the latest.
802.11n USB Wireless LAN Card
Bridged may not always work with a host Wifi adapter, due to strict implementation of the Wifi protocols by either the Wifi adapter driver or the access point firmware. Technically Wifi cannot Bridge, but some combinations of Wifi adapter drivers and access point firmware implement Wifi protocols in a lax fashion so Bridged can squeeze through. If it works where you are, good. If not, you need to choose one of these solutions:
1. go to wired Ethernet
2. pick another Virtualbox network type or two (NAT and Host-Only cover most situations but not where the guest must be on the host LAN)
3. use a Virtualbox USB filter to put a USB Wifi adapter directly into the guest (see
USB basics and troubleshooting).
