I've searched around, and to my surprise it appears I'm the only person with this issue.... Every card I've got is injecting ssssllllloooowwww as heck and only injects 10% - 30% when testing injection.. The weird thing is that it's happening with every card I own:
Ubiquiti SRC
Ubiquiti SRX
A few RT73's
A few Realteks
And even my Buffalo Airstation w/ a broadcom

Even have Ubuntu w/ 2.6.27 (all drivers properly patched) and same thing, wtf? Anyone got any ideas? Could this be a problem with the newer kernel? *awaiting response and compiling older kernel*
