Here's a wierd thing I noticed with Mint 14 (Kernel 3.5.0-17-generic). I bring up my wifi in monitor mode and don't run any user interface on it (EG: airodump, tcpdump, wireshark,...) and I get dropped frames. If I do the same thing in Mint 13 (Kernel 3.2.0-23-generic), I do not get any dropped frames (Both are using a Ralink 3070). Does anyone know what's up with Mint 14 and the dropped frames?

Mint 14:

Code: Select all

wlan0     Link encap:UNSPEC  HWaddr 00-A1-B0-21-D2-6B-00-00-00-00-00-00-00-00-00-00

As you showed it's not a Mint thing but a kernel thing. And would have to ask the kernel developers about that.
As I am starting to get tired of things breaking or lesser robustness like my wifi due to kernel upgrades.
Or buggy nm-applet that has never reached stable or problem free as was still like that in 2007.
loses connections and will not reconnect have to manual turn off wireless and then back on.

I know it's a kernel thing, I thought I would just point it out to others. So if they see the same thing, they would know it <<is>> a kernel thing. I tottaly agree with your view on how stabe the kernel is <not> and/or the system utilities such as NM.
