Thanks. II did get an error about depleted entropy at some point when starting hostapd but I went ahead and installed haveged and it still doesn't work. It doesn't even work when configured as an open AP. I checked the kernel config and I had VLAN support disabled. I've rebuilt it but can't reboot right now. Maybe it's required even though I'm not using VLANs? -- Fernando Rodriguez
