wifi not working


Ive recently installed linux mint 18.3 on my lenovo thinkpad t430s,however, when i try to connect the laptop to the internet via wi-fi, it says unavailable, even though my home wifi router is right next to my laptop. also, when i try to turn on the wifi swich via the widget on the taskbar, the switch immediately flips back to the off position, any help to get my laptop connected to wifi would be greatly appreciated.


p.s. my wireless card is a Intel Corporation Centrino Ultimate-N 6300

There are many reasons why wifi might not work, and I think that the place to start is with the system log files – usually found in /var/log.

The most frequent cause of problems, in my experience, is the so-called "WPA2 Supplicant" process, which negotiates and periodically re-negotiates the cipher keys that are used to encrypt a conversation with a password-protected router. (The original "WEP" system used a single fixed session-key which never changed; "WPA2" was able to provide better security using the same hardware by periodically changing the session-key. The "supplicant" process is the engine that does this on your side.)

This is very likely because the drivers for your card are not installed natively. You will need to set up a wired connection, download them and install them.

Apparently Mint has something called Driver Manager. Run that after setting up your wired connection.

EDIT: This doesn't bode well.

EDIT2: There are workarounds should you get it working, for instance: https://www.linuxquestions.org/quest...-a-4175599455/

To be honest there is quite a lot on this issue on Google and on this very forum [and 125 - yes, 125 threads on the Ubuntu forums]. I would recommend doing some reading.
