18.104.22.168 seems to be missing drivers usually located in the repo at (kernels dir)/drivers. Perhaps they were included in the modules, but I haven't seen word of it. I'm going to try 22.214.171.124, as the drivers are obviously there and I've seen a couple of good reports on it. I don't see how this would have been missed, and I'm most likely wrong, but perhaps the "missing" drivers (e.g. ndiswrapper) are needed by your newer machine.
This post awaits other's correction.
