GPIB<->WIFI on Agilent Network Analyzer 4395A was broken.
The connection was fixed by replacing and configuring the LINKSYS bridge.
Kiwamu and I have identified that the LINKSYS bridge was guilty.
I knew that we had another one in the bathroom, I configured it.
HOW TO CONFIGURE IT
The new unit works fine.
I checked the malfunctioning unit and the configuration was the same as the others.
The bad one detected the existence of 40MARS during the configuration, but it does not establish
the connection in the actual use. I am afraid that something is broken or some setting is lost
during the power supply shutdown.
