Ok, thanks for checking, that's good to know.

Channel 3 should be fine, we just had reports about channel 13 failing.
2.6.35 includes the QoS fix, so I'm not sure what the issue could be
here.

Typically such ancient APs have issues with the supported rates bitmap,
could you maybe try to revert 76f273640134f3eb8257179cd5b3bc6ba5fe4a96?
This is the only relevant commit I can find between .34 and .35.

However, if that doesn't help this seems like an ideal candidate for
bisection, would you be willing to try that? I'd restrict to wireless
code, i.e.

git bisect start -- net/wireless net/mac80211 drivers/net/wireless/iwlwifi
