[SOLVED] wifi-menu doesn't work when interface is already UP (guide)

If I follow the Beginners' guide to a letter when connecting using wifi (https://wiki.archlinux.org/index.php/be … e#Wireless) it just won't work. It works fine if I do not set interface wlp2s0 UP. It also works if I set UP the interface and run 'iwconfig wlp2s0 essid "adsl" && dhcpcd wlp2s0' (I'm connecting to open network). However it just doesn't work if I follow the guide.
I'm using laptop Lenovo X201i (Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)).

Meanwhile:

Can anyone confirm or is this some specific issue/case?

EDIT: I see that the wiki has been updated and fixed by Kynikos.
