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

[Derek C]

Hi Sean,

I've had better luck with ahdemo mode (no network splits but no security
either...).

I've had lots of problems with diversity settings with various hardware
including WRAP x86/CM9 cards and Ubiquiti NS2 units -I still don't know
what the right settings are really and sometimes setting diversity to 0
seems to be ignored because I see the txantenna and rxantenna numbers
jumping around anyway - it eventually seemed to work so I looked the other
way :s.

I've settled on kamikaze 8.09_rc1 (rc2 and the new stable releases caused
me a nightmare and lots of lost days with not being able to make one node
ping a very nearby node so a problem with madwifi versions maybe?) - this
is weird and I should really look into it a bit more.

Derek
