Removing A Network Bridge
Many times when Windows automatically configures
network settings, it installs a device known as a
Network Bridge, which essentially merges two separate
network connections into one, so all devices connected
to one network can access the other. If this happens
between your wired and your wireless connection, it can
cause network outages. Removing the network bridge
alleviates the problem and will not cause any ill
effects to your connection.
