Acer unable to fully connect to WLAN - cannot acquire IP address
A friend asked me to look at one of his laptops that was not working properly on his network (wired or wireless).
I brought the laptop home and sure enough I could not connect it to my own WLAN (Buffalo AirStation, WPA-PSK(AES)) so decided to do full reinstall.
I did a factory reinstall, after which it was able to connect to my own WLAN with not problems. I let Windows Update do its thing and approx 72 updates were downloaded and installed. Finally, it downloaded and installed SP3 which I let it complete overnight. The following morning, no WLAN again. The wired NIC works fine.
Main symptom is that the WNIC appears to connect to the WLAN but is unable to obtain an IP address. I've tried allocating static IP and this makes no difference so I don't think it's a DHCP issue per se.
Laptop is an Acer Aspire 5002WLMi. WLAN chipset is Broadcom 4318. Driver is latest available from Acer website (188.8.131.52) dated 21-Dec-2004.
I have now tried connecting to a nearby unsecured WLAN and this works.
Tried re-entering the WLAN key to no avail.
Tried switching between Windows and Broadcom utilities - no change.
EDIT - I may have been wrong about WLAN working OK following factory reset. I tried this again and WLAN will now not connect to WPA AP.
