Comment 19 for bug 429748

That's on a Vaio P11Z

$ lspci | grep -i Atheros
02:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

With backports-modules installed the laptop does rarely (on startup) connect to my b/g/n network,
and if it connects it is only usable for a short time (or little traffic?) although network-manager
keeps showing the connection as active - I can't even ping the router reliably.

There is no obvious difference between a/n and b/g (couldn't make a successful connection trying a few times).

Without the backports-modules I can connect to the b/g network, but not to the a/n network.

For me the network is always visible though.
