Public bug reported:
I have an Intel Ultimate-N 6300 wifi card in a Dell E4310. It works
perfectly fine with an 802.11g router, but causes constant dropouts with
an 802.11n router (Linksys WRT610n).
The card connects to the access point fine and works well for a while.
Usually under load it then stops working and a bunch of errors are
printed to dmesg. After asking it to reconnect it usually works again
for a while. This only appears to occur when connecting to an 802.11n
router, and occurs using both 2.4GHz and 5GHz specra.
I have tested 2.6.35-rc4 from mainline (maverick build) and it has the
same effect.
