#1316: Association failure in infra mode/association lost when client is idle for
a long time(infra mode)
--------------------------------+-------------------------------------------
Reporter: swagle at marvell.com | Owner: jcardona
Type: defect | Status: new
Priority: normal | Milestone: Untriaged
Component: wireless | Keywords:
--------------------------------+-------------------------------------------
My current setup is using an Eth-USB adapter due to which eth0 is the
wired interface and eth1 is wireless.This bug is not reproducible at all
instants(to be kept under observation).Sometimes the client also looses
association when kept idle for a long time.
