Issues with Surface Pro and the Global VPN Client

Description
Global VPN client cannot obtain virtual adapter address when MS Surface Pro wakes up from hibernation.
Resolution
This issue is caused by a high MTU size on the Surface Pro's WiFi adapter and is not a SonicWall Global VPN client issue.
A MTU size of 1420 resolves this issue but appropiate MTU size may vary from case to case.
CAUTION: This is not supported by SonicWall and all modification to the local system are done at ones own risk.
On the Surface Pro open a command prompt and follow the steps below:
- Type netsh interface ipv4 show subinterface
- Press Enter.
- You will see a list of network interfaces.
- Type netsh interface ipv4 set subinterface “Local Area Connection” mtu=1420 store=persistent
You should replace Local Area Connection with the name that appeared in the “Interface” column from steps 1-3. - Press Enter.
- Restart your computer and then test again.
