I presume that ComCast is Cable and not DSL? Again, do you know if your ISP modem has an internal router built in?
How about trying G mode only at 2.4GHz with out any password as a test? Will they connect then? I'm wondering if there is a problem on the mode they are using or if there is a Security mode problem. Let us know what happens with out any security set for a test.
Comcast is Cable (Fiber at the Line and Coax as it comes into the building)
I have no Idea if there is an internal Router.....
INTERNAL ROUTER INDEED WTF This Modem is different then what we had downstairs ( Before the Toilet Floods, along story for later) this one says......

I tried a connection test on one of our two Wii(s) with the the Security Disabled.... still wouldn't connect with the Nintendo Error Code 51330... "Incorrect key?"
but I have double, Triple, Quad, and so forth verified the Key's Accuracy.
ok second test round:
Inactive
Wi-Fi Protected Setup : Disabled
Guest Wi-Fi Protected Setup : Disabled
Security Mode : Disabled
With these Settings I retried the Wii's Connection and FAIL with a Slightly different error code
Nintendo Wii Error Code: 51331, I usually got Code: 51330
All our Manual IP Setting are Good....
