ad-hoc to JoikuSpot

[David Brownlee]

JoikuSpot is software which lets a Symbian S60 3rd Edition
share its internet connection via ad-hoc Wi-Fi.

I can happily connect via a WindowsXP box, but I'm not
having any luck connecting via a NetBSD (This is the first
time I've tried using ad-hoc 802.11 networking, so its
quite possible I'm missing something basic).

I've tried on two NetBSD 4.0/i386 boxes, one with a wpi and
the other an ath wireless chipset.

# wlanctl -a reports:

Adding 'chan 1' to the initial ifconfig line doesn't seem
to affect matters

Anyone have any thoughts as to what I'm missing?

Thanks

It shouldn't be necessary to specify the BSSID. The BSSID can actually
change over time. Specifying the channel is helpful.

Are you sure that ad hoc mode is supported on wpi(4)? Also, do you have
to load a special firmware before you can use ad hoc mode?

ath(4) supports ad hoc mode very well. I am curious how it failed.

mediaopt adhoc? I would have thought it was implied by your post, but
I don't see it in the ifconfig output you pasted.

That would be it - thanks!

Amusingly enough the word 'adhoc' does not appear anywhere
in ifconfig(8) and only in an caveat in ath(4) (At least
in NetBSD 4). NetBSD may be setting the bar a little high
for someone setting up an adhoc connection here :)

I ot it to work on ath(4) - after adding adhoc (ahem). Unable
to get it to work on iwi(4) or wpi(4). Unfortunately the
laptop I want to use has a wpi built in. I'll check if its
a mini pic and can be swapped for the ath(4), but does anyone
have suggestions for usb wifi cards which work with with adhoc
under NetBSD?

Thanks again!
