Single G is good for the computer and XBox 360. PSP, however, timed out again. Gonna try in B only, then B+G.
Router's great... It's the PSP that's the problem.
*edit
Single B is good for computer and PSP. Xbox is a no go, though. B+G next.
*Edit2
B+G is good! Connection across the board!
Thanks for the help, good sir, and go D-Link!
