I was thinking of building a new wifi AP. The following is a stream
of
thoughts on the subject. Any constructive suggestions are welcome.
Requirements:
* Compatibility with Androids, Kindles, x86 Linux, OpenBSD wifi
clients
* Strong in-doors signal
* Maximum control
Nice to have:
* Combine the AP with the wired Ethernet OpenBSD router.
* Low power& noise.
Complications:
* A few wireless networks in nearby houses
* OpenBSD AP capable devices have a CAVEAT: Host AP mode doesn't
support power saving. Clients attempting to use power saving
mode
may experience significant packet loss (disabling power saving
on
the client will fix this).
Possible design:
* OpenBSD host with 2 or more wired Ethernets
* USB wifi device (free to switch host hardware)
* External Hi-Gain antenna
Detailed implementation:
* small i386 or armish machine for the host (Soekris?)
* Hawking HWUG1 (rum(4)) ( http://goo.gl/ccd6Q )
rum(4) did not like hostap mode the few times I tried.
via the man page I think this is a problem with all usb radios
so I tend to stick with pci/pcmcia cards ral(4) for my APs,
however I have not had any other problems with rum.
And fwiw I have had the worst luck picking out ath radios.
* Hawking HAI7SIP Antenna ( http://goo.gl/Axg7j )
Does anybody know if the CAVEAT above present a problem in real life
for
the clients I listed?
Thanks
Greg

I have a ral(4) in my Soekris. I tried it once, but the performance was
horrible. Maybe I did something wrong?
$ dmesg|grep ral
