On the 2 computers running Win 98SE the connection to the AP drops them randomly every 18 to 36 hours.
I have a D-Link NIC in both computers one is a DWL-G659 and the other is a DWL-G520. My AP id a D-Link DI-624. This did not happen prior to enabling security features. I have WEP on an open key.
I have to reboot the AP to resolve the problem from a wired computer.
