hyper-v keeps disconnecting

-
Hi,
My hyper-v windows XP machine keeps disconnecting from network.
When I start the VM everything is fine I have connection to internet but every 2-4 minutes I loose connection. Sometimes the connection gets back after 30 sec and sometimes it never gets back until I disable and re-enable the network bridge from the virtual switch.
The host machine has no network issues and is connected 100 % whole time.
Environment:
Host: Dell Laptop, Windows 8.1, Wireless network card, virtual switch on wireless network card (external connection type with allow management operating system to share adapter).
Hyper-v VM windows XP.
How to fix this?
Thanks in advance.

Unfortunately not. It sounds like it may be an incompatibility betweenthe wireless NIC and Hyper-V. Wireless NIC's have always been a problembecause they don't always support everything needed for something likehyper-V. It's better in the current version of Hyper-V than before, butit's still not perfect. Changing NIC's or waiting for driver updates isabout it.

Since this is a laptop - disable all power savings setting on the wireless card.
The driver could be putting the NIC into a low power state, a sleep state, or turning it off all together when the management OS is not using the internet.
these power savings features of the NIC driver are never compatible with VMs.
