Comment 45 for bug 1269883

Same here with Asus UX32LN and Linux 3.17, the symptoms look very similar to already reported here. Under heavy file transfer, the network connection abruptly stops, and activity LED on my dongle continue blinking like mad.

Wireshark shows the adapter is sending ARP requests as it would normally do, but does not seem to receive any reply, even though the Wireshark on the other end sees the ARP replies. This seems to point to broken RX handler?

`sudo rmmod ax88179_178a && sudo modprobe ax88179_178a` helps. Nothing suspicious in dmesg at the time of failure:
