Thanks. I have a 4965, using kernel-2.6.29-0.197.rc7.fc11.x86_64 (Intel(R) Wireless WiFi Link AGN driver for Linux, 1.3.27kds). I can connect to 802.11n on 2.4 GHz, but it never finds the 5 GHz cell of the AP. Is 5 GHz 802.11n supported yet? For that matter, shouldn't I be seeing the 802.11a from my APs? How do I get this thing to scan the A/N 5 GHz band? Thanks. #iwlist wlan0 channel wlan0 11 channels in total; available frequencies : Channel 01 : 2.412 GHz Channel 02 : 2.417 GHz Channel 03 : 2.422 GHz Channel 04 : 2.427 GHz Channel 05 : 2.432 GHz Channel 06 : 2.437 GHz Channel 07 : 2.442 GHz Channel 08 : 2.447 GHz Channel 09 : 2.452 GHz Channel 10 : 2.457 GHz Channel 11 : 2.462 GHz Current Frequency:2.437 GHz (Channel 6) I turned on the debug flag and verified that the driver is seeing 5.2 GHz band channels as allowed: Mar 6 17:45:08 l kernel: ieee80211 phy5: U iwl_init_channel_map Initializing regulatory info from EEPROM Mar 6 17:45:08 l kernel: ieee80211 phy5: U iwl_init_channel_map Parsing data for 56 channels.
