Sluggish performance when accessing a database over network with Atheros Wireless Adapter

Our application is setup to work over a network to share an MS Access Database to multiple workstaitons. We have recently noticed that workstations connecting to the server(where the database is stored) using wireless adapters with atheros hardware causes our program to function very slowly.
We are currently using DAO 3.5 with Access 97.

i am not sure i understand what you mean by "bound". In terms of what is going on, the amount of data varies depending on which form in the application is being loaded and what processes are triggered. Alot of the forms already use queries in the database. The only thing that seems to be consistent is when the wireless connection is using Atheros hardware, it works very slowly.

Bound means your application has a form that has a RecordSource, and your controls are "bound" to a table column via a ControlSource. An "unbound" application would be one where you request data from a server, then present that data to the user (i.e. you'd fill the textboxes, combos etc), and then you would update the data on the server when the user makes changes. In a "bound" application, Access takes care of all these things.

The amount of data coming across the network doesn't vary at all; when Access has to run a query, the entire table is pulled across the network, then the workstation handles the query and returns the results ... NOTHING is done on the "server", since Access/Jet is a file-based database.

Still, using Access on a wireless network is just begging for trouble. It might not happen today, or tomorrow, or next week but you will have issues with this, it's just a matter of time. Access doesn't really like wired networks either, but they are much more stable than wireless.
