Global VPN client cannot obtain virtual adapter address when MS Surface Pro wakes up from hibernation.
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
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.
