Method 1 -> If the computer is behind a router, remove the router and
connect the
computer directly to the internet. This may require setting up a new
connection to
the internet.

Method 2 -> If there is no router on the network you will need to adjust the
MTU
from within Windows. The following article describes the process in detail.

Method 3 -> Change the MTU in the router. This is outside of the support
boundaries but can be done through the Tird Party Vendor or if the customer
knows
how to access the relevant programming in the router. This should only be
done if
for some reason needs the router needs to stay in the network.
