[ath9k-devel] TX packets dropped

[David Ehrmann <ehrmann@gmail.com>]

I guess I got the card wrong--it's a routerboard R52N.  It uses the same 
chipset, though.  Here's what's weird: I removed the the card and put it 
on a Via Mini ITX motherboard.  I used the exact same OS and 
configuration.  My problem went away.  After making sure it wasn't a 
power supply issue, I reassembled my old configuration, and now it's 
working.  Currently, I'm seeing only 1.1% TX packet drops (and 4.5ms 
jitter).

That means that the mini PCI card could have been seated wrong, there's 
a short in a pigtail, the pigtail-card connector had problems, or 10 
feet and two walls did this.  I'm going to move it back, but if that's 
not it, this problem's really worrying because it probably involves a 
bad pigtail, I don't know which one it is, and it could happen again if 
things get bumped around enough.
