Comment 18 for bug 102982

I've been having the same error message, and my Intel IPW3945 Wireless adapter would be extremely hard to get working. I would have to modprobe and other manual things, and still it wouldn't work.

I'm using a custom 2.6.23-rc3 git kernel (kernel.org). The module (ipw3945) would load, and so would the regulatory daemon (ipw3945d). It would even show what wireless connections there are, but would never be able to connect to them.

It seems like the message: "intel_rng: FWH not detected" is related to the non-working wireless because on the default ubuntu kernel (2.6.20) it doesn't give that error and wireless works perfectly! "Intel_rng is the Intel hardware Random Number Generator. FWH is the FirmWare Hub through which the RNG is accessed."

I looked at my kernel config and found out that I have build intel_rng directly into the kernel, not as a module! I'm recompiling right now and will see if that fixes the problem. Compile as a module or not at all, unless you are 100% sure your computer has a Intel_RNG!
