InfoMover PCMCIA Card in AST Laptop Fails to Work Under WFWG

• Microsoft Windows for Workgroups versions 3.1, 3.11

SYMPTOMS

The National Semiconductor NE4100 InfoMover PCMCIA network card works correctly with most laptops. However, if you use this card in the AST Ascentia 900N laptop (portable) computer, you may be unable to log on to busier networks under Windows for Workgroups.

CAUSE

The AST Ascentia 900N uses the relatively rare VLSI PCMCIA controller chip. The AST Ascentia 900N also ships with the Cardsoft 3.1 PCMCIA card and socket services, which is the first card to support the VLSI chip. However, Windows for Workgroups runs well on the Ascentia with other PCMCIA network cards installed, runs well in most cases with Cardsoft software, and runs in other laptop computers with the NE4100 installed; therefore, Microsoft has been unable to determine which element causes the network logon problems under Windows for Workgroups.

STATUS

National Semiconductor is aware of this problem and will supply more information as it becomes available. You can contact National Semiconductor at (800) 231-6072.
