Need a little help with lag spikes

hey guys i know there are some tech savy people in here with networking. I had some serious rubber-banding issues all night tonight , more then I think most had at least. I was rubber banding every couple of seconds but chat was working so not sure if this is fully on their end or mine to. Anyways we decided to add two wireless 300 meg belkin usb wifi adapters instead of doing direct connect to the router . Is there any settings besides port forwarding behind the firewall to guild wars 2 that we can tweak that will help out with rubber banding and lag spikes through wireless? I know they are not the best but im sick of having wires all over the house as we have to have our blue ray for the daughter with a direct connection to the tv.

I angered the clerk in a clothing shop today. She asked me what size I was and I said actual, because I am not to scale. I like vending machines 'cause snacks are better when they fall.

We're having an issue with one of the Internet connections in our North American data center. Anyone connecting to us through that link is experiencing bad lag right now. Our network operations team is working to get it resolved.

BOOYAKA!
The lag issues tonight were not you, they posted a system wide message saying they (ArenaNet) were having internet problems with both GW and GW2.
ive tried this before a long time ago when we did this once before and it would happen in wow where one pc would get huge spikes and the other would be normal but everything else like video dsl reports etc would say my connection was perfect. We never figured that out about fixing it so we went back to wired the last couple of years. I know computers well just not networking hardly at all.
First, this kind of lag and espesically rubberbanding has not been part of any of my previous GW2 playtesting experiences. So, rest assured that this is not how the game will be after launch!
As others have said, there were network issues which produced most of the problems. I have seen this with a number of other MMOs, both live and in testing. It seems to happen more often in pre-release testing, which makes me wonder if the unusual spike in bandwidth to a single i.p. doesn't trigger a throttling reponse on some ISPs and internet hubs. Usually the solution is arrived at by the developer working with the providers who own the bottenecking points along the routing path to ensure that the traffic can move freely, sometimes by re-routing network traffic around the problematic nodes.
The last point I'd make, once again from having a lot of previous MMO beta experience, is that during stress tests, developers almost always create their own artificial bottle necks or tweak network and server settings in order to deliberately put added stress on parts of the system. This helps to identify potential problem areas and also allows them to chose the best configuration and server population limits to ensure things are smooth when the game launches.
I've seen MMOs that have had issues in every beta test and only sometimes have solved those issues for launch. However, GW2, like most MMOs, actually ran with little or no networking lag for most people for most of the BWEs and even most of the previous stress tests. Things will not be worse at launch than their best during testing and their best during previous testing was much better than the last two days' stress test events!

The asura area seems to have lots of bugs for some reason..............or at least it seems that way since most people are claiming these same issues mostly in that area
They moved Occlusion calculation off of the GPU and to the CPU, due to technical reasons that were negatively impacting performance. If they can get a fix via driver support from NVidia/AMD/Intel, they may be able to put that back on the GPU down the road. A side effect is that there are some areas of the game where the new occlusion method is improperly culling objects from the scene that it shouldn't be. (The point of occlusion is to calculate quickly which objects are not in the camera's field of view and then excluding them from being sent to the GPU to be rendered to the screen, thus saving bandwidth and processing power that would be wasted on objects you don't actually need to see).
They need to carefully comb through the world and find places where these issues are happening and make adjustments to ensure that things aren't being dropped that shouldn't be. I don't know the technical details, but this may include, in some cases, forcing some meshes to be excluded from culling all together. tyhe more they would exclude from culling, the more of a performance hit those things produce when they get calculated with out actually needing to be shown on the screen. They may also be able to adjust the calculations used for determining what should be culled, so that there is more of a buffer between only calculating meshes on screen for a given frame and over-calculating meshes near the edges of the frame.
I definitely hope there will be a fix before launch, because it's very immersion breaking to have objects and terrain disappear like this.
Arenanet had posted a command line parameter that people could use to force the old method of occlusion. "-umbra gpu" Performance will likely suffer a bit, but for some people, the trade off may be worth it. (I'm considering it myself).
Here is a more detailed explaination of occlusion culling:
