Samsung bd-p1600 wireless connection to 2wire 1800HG router

Can't get it to connect. Settings appear correct, but when it tries to ping the gateway it fails. Any suggestions? I'm a novice at this, but I copied all the settings from the network page and can't figure it out. The same adapter works fine on the TV, but won't connect when I put it on the blu-ray. It's Samsung's wireless lan adapter that works with the 2009 blu-ray player and the 7000 series LED TV.
