I'm also a Telenet user and I'm constantly getting Centipede errors and some other network related errors every now and then. I kept trying and managed to complete the lvl 1 and lvl 2 missions, but it almost always disconnects me with centipede errors. One time I was looking at a firesquad member and I could see him move around so his packets were reaching me without problems, but it disconnected me right after looking at him. I forwarded all ports to my ps3 already.
