Hi Eric,
I've been through your same situation, under a very stressful
circumstance: implementing my master thesis. I found out that that
most adapters really suck at implementing ad-hoc mode. However, there
are some very decent adapters that are cheap and have very stable
drivers.
* Atheros: As Simon said, it is one of the best. Most laptops come
with some sort of atheros chipset built in. I was not happy on finding
external adapters with atheros chipsets, but that was about a year
ago. Things may have changed.
* Edimax EW-7318USg (Ralink chipset): Today, it is one of the best. No
cell-splits, no hassles, no problems. Rock-solid driver, works
"plug-n-pĺay" on Ubuntu 9.04 and 9.10. In addition, it's very cheap
and supports external antennas. USB.
* Alfa Networks AWUS036H: Very, very good... but a little expensive
(at least here in Brazil). The best driver for this adapter is the one
with the Backtrack distribution (www.remote-exploit.org). Since it is
used a lot for Wardriving, etc.. monitor and ad-hoc mode is very
stable. USB.
My experience with these three adapters was awesome. They saved me :).
Hey guys, perhaps this kind of information should be on the wiki.
That may help a lot of people. I could elaborate into more details if
you guys are interested.
best regards,
