i have a slightly weird problem with 5ghz that im not sure is related to the hidden channels problem you guys have.

i have a ddwrt router with single/double/dynamic bandwidth options {20, 40, 20/40, respectively} for setting the extra channel in 5ghz.

if i choose 20, the n9 works perfectly correctly, and remembers the network.
if i choose 40, the n9 cant see it at all {makes sense}

the weird problem is if i choose 20/40.
my n9 can see the router, connect to it, and get on the internet.
however, it sees the network as a new network every time, prompting for the wpa key. it stores a copy of it each time in the list of internet connections, and no fiddling with the settings can convince it that the network is the same network, even while its still currently connected.

anyone else experience this, and/or have a workaround?

{if the networking code is available somewhere, this is probably a one-liner to fix. anyone know where the source might live?}
