Visited my Dad's network with my new ral(4) driver and had no luck to associate with the access point. So, what different from my home AP? Both are running mixed 802.11b+g mixed mode and using WEP (yes, I know) for encryption. The only obviously different is the key length: 40 vs 104 bits.
Anyway: there's certainly more work needed, such as integrating all those 60+ patches made by the OpenBSD guys.
