Make, model of all etc?

I have a virginmedia SuperHub and I went went to my router settings to try and improve my wifi's performance but I ended up making my laptop incompatible with my router. My phone and my dads tablet are fine but my laptop is the only PC in my house so I can't use another to change the router settings back. I've tried using an Ethernet lead but it wouldn't work. Is there anything I can try?
