I had an Adsl router installed the other day. I get home and it works fine. Then I try and download Sopcast (a p2p streaming player) alarm lights up red up on my router and I can't access the internet (wireless). I turned the router off and on again. Alarm is not lit up anymore but just power and ADSL are lit up(The WLAN light isn't lit). Now I can't get a wireless connection. If I plug it in diectly I can get the internet, but just not wireless. I tried searching but it just say's it can't find any wireless networks. The router has a reset button on it. Should I just press that?

What do you think the problem could be?
