A Trouble with Glitched Out Router.

So my router has glitched out after I changed my SSID and password. Seems that he can't handle spaces. I tried setting my SSID to Ladasno Network, but got only Ladasno and password is Cannot Know, but now I can't login to my wifi and edit settings. I'm 100% sure that password is correct since it is saved in my chrome password library so I could copy and paste it. So I'm asking how can I hack WPA2 (No WPS hacking, No Handshake Hacking) encrypted wifi.
