Comment 27 for bug 1293569

Hi Emmanuel.

Original submitter here:

Unfortunately I haven't had time to try to capture packets during failure, but I'm open to doing that (hopefully today or tomorrow).

Here are the details for my AP:

Overview: This is one of the standard ATT Uverse Modems. No specific config changes (besides password), otherwise stock standard.
Manufacturer: Pace Plc
Model: 3800HGV-B
Software Version: 6.9.1.42-plus.tm
Wireless Mode: 802.11b/g
Auth Type: WPA-PSK (TKIP) and WPA2-PSK (AES)
DTIM Period: 1
Rate: 54Mbps

Others in thread who are affected, please post an overview of your AP so that a profile can be built.

Regards,
Barry
