I backup the old driver using \r\n\r\nfor file in /lib/firmware/iwlwifi-5000-*.ucode; do sudo mv $file $file.orig; done\r\n\r\n I am using iwlwifi-5000-5.ucode. After experiment, I try to switch back to the old working driver by \r\n\r\ncp iwlwifi-5000-5.ucode.orig iwlwifi-5000-5.ucode\r\n\r\nAfter restart the network manager, the WiFi does not work. I am having deauthenization problem all the time (with reason 3).\r\n\r\n  I notice that there is also iwlwifi-5000.2.ucode due to \r\n\r\nsudo ln -s iwlwifi-5000-2.ucode.sigcomm2010 /lib/firmware/iwlwifi-5000-2.ucode\r\n\r\n So I change the name to iwlwifi-5000-2.ucode. After restart the network-manager, still I cannot connect to any WiFi.\r\n\r\n Is there any procedures that I should follow to 'restore' the old working intel WiFi 5000 series driver?

I can see a lot of messages in terminal like:\r\n    received 233 bytes: id: 26 val :1 seq: 0 clen: 233\r\n\r\n    And I ping the wireless router in another terminal. However when I try to load the CSI.dat using the matlab code read_bf_file, it always return an empty cell.\r\n    Is there any suggestion on the wireless router? Should I just use another 5300 to communicate with the current one, so as to capture CSI?\r\n\r\n   Thanks!"}}
