Bug#578262: Intel 5300 wireless does not work on Acer, TravelMate6293.
Thank you for your replay.
I applied the supplied patches:
0001-mac80211-explicitly-disable-enable-QoS.patch
0002-iwlwifi-manage-QoS-by-mac-stack.patch
(in this order)
to the Debian's linux-2.6-2.6.32 kernel source, but it failed during
iwl-core.c compilation with an error message:

If I understand the patches correctly, the 0002...patch removes a "void
iwl_reset_qos(struct iwl_priv *priv)" function and unused qos_cap bits.
But the function is still used in "int iwl_init_drv(struct iwl_priv
*priv)" function in the "iwl-core.c". I removed a part of code:
---
iwl_reset_qos(priv);
priv->qos_data.qos_active = 0;
priv->qos_data.qos_cap.val = 0;
---
as it is done in "int iwl3945_init_drv(struct iwl_priv *priv)" at the
end of the 0002....patch.
With this adjustment (attached
"0002-iwlwifi-manage-QoS-by-mac-stack-adjust.patch" file) I can compile
the source and it works fine with APs with which it didn't work before.
