Re: athn(4) WPA2-PSK software crypto CPU loading

In I asked about the CPU overhead of doing wifi WPA2 crypto on a slow CPU. I have received two very useful off-list replies, which I'll summarize here for the archives: One person has a very similar setup to the one I described (athn(4), At

athn(4) WPA2-PSK software crypto CPU loading

I'm considering setting up a wifi access point using a PC Engines ALIX board (500 MHz AMD Geode LX800 CPU, 256 MB RAM). One way of providing the wifi is via a radio card (e.g., the PC Engines DNMA92) in the ALIX box. This uses the Atheros AR9220 chipset, which has good OpenBSD support -- includin
