A client of mine has an Asus R1F tablet running Windows XP Tablet SP3. It has an Intel 3945ABG wireless card; wired Ethernet is a Realtek something-or-other. In the past few days, it's developed an odd problem:
- WiFi authenticates, but can't get an address via DHCP.
- plug in wired Ethernet - both interfaces get good addresses
- unplug cable, WiFi continues to work until shutdown.
- Next morning, repeat process.
I've tried:
- turning WiFi off/on (there's a slider switch)
- disabling/re-enabling via Device Mangler
- uninstalling and reinstalling the driver for the 3945ABG...
- changing from Intel Pro/SET to Windows Wireless Zero Config (and back)
- restarting the router
- changing the static DHCP assignments at the router
- upgrading the router firmware, just on general principles
The router/access point is pfSense 1.2.3RC1 (was 1.2.2); wireless card is Atheros-based. None of the 12 other users (5 with tablets) are having problems.
