Comment 8 for bug 315438

I have this issue on a brand new Acer Aspire 5536 using 9.04 with all updates as of 17-may-2009. The issue only seems to occur when there is significant traffic such as downloading updates or transferring files from the network. the card is reported as an Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01).

Output of 'sudo lshw -C net':
