Wireless DHCP doesn't work until wired Ethernet plugged in
- by MT_Head
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.
