Error 90k's?

[PEANUT]

For the past 3 weeks, I have been getting constant Error 90ks, to the point where I can't do any instance content. I have no idea what it is. I have excellent internet connection my computer is saying. I have taken basic steps, clearing my DNS Cache, reseting my router, etc. nothing is working. I assume a ping is getting lost somewhere causing this?

I have had this problem months and months ago, and the result I remember was playing tag with my ISP. They kept telling me it was not on their side it was the games, then tech support told me to speak to my ISP's Tier 3 people. Tier 3 people got back to me saying same thing, it's not their fault it's the game servers. I don't know what to do.

Is anyone else having this problem? Are there any detailed ping tests I can do to see if/where my signal is getting lost?

Please, please, please help! 3.0 is right around the corner, and I don't want to continue dealing with this annoying issue! Thanks in advance... ;_;

P.S. I am using a Wireless Router to connect to my home router. I have been playing fine for the most part since the game started, and even upped my Internet speed a lot to help out. I currently live in New York, so I am not that far of a distance from the Canadian data center North America uses, and I am on Excalibur(a very populated server, so that might have something to do with it?).

I'd be glad to share any other information anyone willing to help might need.
