I have a similar issue, at times I can run dungeons and what not, and at others I simply can't because I get whacked by serious lag. Today was a no go for me, I tried low level roulette, got DD, got hit with lag at first boss and D/Ced multiple times. Probably the worst lag I've had in the 2-3 weeks I've been randomly suffering this.

Kerberon how exactly do I understand this pathping report?

I'm assuming these are my problem points? mtl= montreal? And I think I figured out how to read it now, took a look at the beginning. Well this is the first time I've had this issue with a MMO.
