Cisco AnyConnect VPN reconnect resulted in different configurations settings error
Quickest way is to start a Windows Command Prompt from Start > Programs > Accessories (in Win 7). Make sure you right-click and use Run As Admin.
netsh interface ipv4 set subinterface "Local Area Connection" mtu=1300 store=persistent
or use "Wireless Connection" if appropriate.
You can also type
netsh interface ipv4 show subinterfaces
to get a list of interfaces.
Or download a utility to do the job for you, c/o Cisco
Could be worth experimenting a bit to find what is the most appropriater MTU, using a higher value of 1400 might give slightly better performance.
