Which security type?

[JewishBacon]

Usually I use WPA2-psk,  but my new router does not have that one. I know not to use wep, but I dont recall any of these other ones in linus's recent video....which one should I use?

The one highlighted in blue is the one that I'd recommend using.

WPA2-PSK and WPA2 Personal are the same thing. PSK just stands for Pre-Shared Key.

 

WPA2 Enterprise uses different 'Pre-Shared Keys' per user and usually requires an authentication server.

 

You can either use WPA2 Personal or WPA2/WPA. The WPA part just makes it easier for folks who don't want to mess about with router settings/keys when adding devices to the network, you usually just press a button on the router and enable WPA on the device and they connect that way.

Maximum security -  WPA2 Personal (no auto adding devices without the password).

WPA2/Enterprise doesn't use a pre-shared key, it uses 802.1x, RADIUS or another similar technology (TACACS+ as an example). It's feels just like logging into an account on a Windows domain, everyone has their own login credientials.

 

As for what the OP is asking here, WPA2 Personal is the best option. The one you have highlighted is a mixed mode which should only be used if you are trying to connect legacy devices that only support WPA and not WPA2. If you don't have any legacy devices go with pure WPA2 Personal as this is the most secure. I also suggest dissabling WPS (WiFi Protected Setup) as this is very insecure.

Woops! I mixed up WPA and WPS somehow... Thanks for pointing that out, and thanks for the info on WPA2 Enterprise, I've not delved into it myself, just briefly went over it in college a few years ago... My lecturers weren't the best apparently.

Also make sure that you change from the default SSID and don't choose something obvious. The one vulnerability of WPA is that it uses the SSID to create the key and people tend to pick the same SSIDs. If someone wants to break into your network they will, but if you're using an SSID like linksys, NETGEAR, dlink, default, internet, wireless, wifi, Home Network or even something like skynet? It makes things far easier. Because people have already done the work for those SSIDs.

I'm assuming you mean WPA/2 because WPA uses TKIP which has been known for years to be highly insecure due to having aspects of it which are strongly "not random". But yes, it is always smart to use a non default SSID (WiFi name). I like to have fun with my SSIDs that are for personal use, Bill Wi the Science Fi, It Hurts When IP, The WLAN Before time, etc. you know, the fun ones!
