Hi, I have a Venue 8 Pro 5830 64GB and experience the following drop issue with wifi:

1. tends to drop in the middle of extended downloads/streaming/youtube
2. when it drops, it shows as unavailable and doesn't see my router or any of the others in the area
3. attempting to reset it by turning the wifi slider off fails and it just reverts back to on
4. each time this happens, the failure event details are logged at C:\AR6K_FW_Recovery.log
5. driver restart is required to reconnect, either by reboot or toggling advanced driver properties like the roaming aggressiveness setting 1 or 2 times (disable/enable in Device Manager usually fails to restart it, leaving it with the "yellow ! bang icon")

Reference to others who probably have the same issue (20g and jadesse):

This issue is unrelated to the Windows Update failure and unrelated to those who simply have temporary drops, limited connectivity, or sleep/wake drops. It seems to be caused by the adapter firmware/driver terminating due to a TX (transfer) hang. Could anyone who is experiencing these issues confirm they're also getting that C:\AR6K_FW_Recovery.log and paste the contents of their file?

 

Opening the log in Wordpad, it describes the failure as "Control Endpoint TX Hang":

Please list your specs in a similar way, so maybe we can find a common point of failure.

I hope Dell/MS can fix this issue soon. Thank you for reading!
