wlan router?

Hola,

since my ex-bf decided to steal my deep loved wlan router I'm searchin for a new one but I must admit I got absolute no knowledge about that stuff so guess, I still didn't buy a new one (still hoping for a miracle that someone tells me which one I should buy and gonna install it xD).

So guys, maybe u got any proposals for a good adsl wlan router or at least some knowledge about that technical stuff, otherwise I've to act girl-like and just buy the most expensive one ^^
