I have an Acer Aspire 5000 XP Home SP3 laptop before me with all MS updates installed and all manufacturer updates installed, including BIOS and all available driver updates.
The laptop has a Broadcom 802.11g Network Adapter wireless card installed. It can connect to a unsecured wireless network with no problem. In fact I removed the security from my WLAN and have been surfing with it for the past two days. The problem is that with any sort of security on the WLAN, even WEP 64 bit, it will not connect. It see the network, attempts to connect,and then reports "The wireless network is no longer available."
I have manually setup the WLAN connection under "advanced Settings" but this didn't help.It has shown the same behavior on another WLAN. I checked for the latest driver from Broadcom but could find no downloads for it there. From Acer a driver was available but it was the version already installed. I re-installed it anyway to no effect.
Any suggestions appreciated.
