Hi we recently bought some mobile computer vc5090, we deploy some of them in our warehouse and everything is ok, but those that we use in the factory , had problem to connect to the wireless. We use cisco AP 1200.

Try connecting each one directly to the router to set them up before using them wirelessly.

If that doesn't work, remove the security password and connect without any security.

If this works, re-enter the security keycode and they should all connect no problem.

Just ensure that the security password/keycode is the same on the router as the computers.
