grrrrrrrrrr...cant connect to blk ops /mw3 servers

hi all...i have a sof modded wii, used to connect to blk ops and mw3 online with ease ,recently i've changed my ISP and now i cant connect. its a Zhone router. i made 2 AP with one open(no encryption) with a mac filter accepting the wii alone to connect. i even deleted blk ops saved data ,now i get nintendo wifi connect ,still getting "...cannot connect to server".
i tried the creating 2nd profile fix...nada. game says V 0.0.0
help anyone? i miss playing blk ops and mw3 .
i think it could be a router setting?
or the servers are down?????????????????????????
pls help anyone.

Servers are still online because i was playing it yesterday!!! Check your codes and see if your Router has blocked any links

Like Wolf said, the servers are still online. Hell, I was just playing with a poopdeck full of hacks.I can't think of what the problem might be, but I noticed that once or twice it wouldn't connect, and that only one of my 4 profiles worked - hell, I was even reset (no joke)! So, yeah, everything's working, but you may need to try a different profile to pull it off

jus wanna say thx for replying. still no luck, i guess it has to be a router problem.
