comment Connecting to a WPA2 network
Thanks. is wext mentioned in the output of some command? I never seen it before. iwlwifi is in the output of lshw for my wifi adapter at least.

comment Connecting to a WPA2 network
Thanks. (1) if Iwtext isn't my wifi adapter's driver, what is it? Is it a device file? (2) Why -D in manpage of wpa_supplicant says it expects a driver, if lwtext isn't a driver?

2. Is wtext my wifi adapter's driver or something else? Is it at a lower or higher level than iwlwifi?

comment Connecting to a WPA2 network
1. ISSD is given to wpa_passphrase and stored in wpa.conf in the first command in the quote. Then wpa.conf is referred to in the last command wpa_supplicant -B -Wnl80211 -i wlan0 -c wpa.conf in the quote. Is it necessary to run iwconfig wlan0 essid your_network_name or sudo iwconfig wlan0 essid NETWORK ap 00:60:1D:01:23:45?

comment Connecting to a WPA2 network
thanks. 1. is BSSID same as ap? Is this step necessary, given that ISSD is given to wpa_passphrase and stored in wpa.conf? 2. why not iwlwifi, the wifi adapter driver? Is wext my wifi adapter's driver?

comment What are the concepts of “kernel ring buffer”, “user level”, “log level”?
My second question is: While dmesg prints out the current values of kernel ring buffer, the past/old values of the buffer are stored in /var/log/dmesg. So dmesg output is just a recent subset of /var/log/dmesg content, and they are different. Then are the contents of /var/log/dmesg (not dmesg as in your comment) and /var/log/kernel.log the same?

comment What are the concepts of “kernel ring buffer”, “user level”, “log level”?
Thanks. (1) Is "user level" related to "user space"? (2) From what you said, /var/log/kern.log and /var/log/dmesg should have the same content as the kernel messages? But their contents are not the same.

comment What is the backup file created by checkinstall for?
the third one is whether checkinstall needs sudo. not tar -xzvf backup-<datetime>-pre-<packagename>-<version>.tgz -C / need sudo
