[Olsr-users] Favorite Madwifi drivers, patches and settings for Adhoc?

[Sean]

Interesting. I was having issues with nodes not coming online even 
though I specified the bssid. "iwconfig ath0 ap 02:ca:ff:ee:ba:be"

It wasn't until I started using madwifi-hal-testing did I get better 
response from nodes. This is only with three nodes in a single room.
