Weird problem, Lan works but not wireless?

[RestEternal]

So- i have dsl, and i was using their supplied modem/ wireless router combo. All of the sudden, The wireless stopped working, but I could still get internet access if I plugged the computer in through the regular ethernet port. I purchased a new wireless modem router combo (a decent d-link one) and made a new wireless network. It worked without a hitch for about a week, then the same problem came back. No wireless but fine through the ethernet port. None of my other wireless things work either (360, ps3, ipod touch, laptop).

Any ideas?

Do you lock down your wireless? Secure it? And change the web admin password for your router?

Yeah a Brand new password. It doesnt just use a number, like WPA, It made me make a "WPA-PSK Passphrase"
