Guild Wars 2

This started happening to me too recently. I definitely don’t think it’s a problem with my computer or internet – the game ran smoothly until around last week.
I found this thread yesterday, turns out tons of players have the problem too.

^Some recently had the problem began, such as myself.

Here is what was posted that helped some people (it didn’t change anything for me though):
“1. Navigate to your Guild Wars 2 installation folder.
2. Right-click on “GW2.exe” and select “Create Shortcut.”
3. Rename this shortcut to “Guild Wars 2 Port Test.”
4. Right-click on this shortcut and select “Properties.”
5. Edit the “Target” line to include /clientport 80 at the end.
Note: Please make sure /clientport 80 is outside of the quotes
Correctly Formatted Example: “C:\Games\Guild Wars 2\GW2.exe” /clientport 80
Incorrectly Formatted Example: “C:\Games\Guild Wars 2\GW2.exe /clientport 80”
6. Once completed, click “Ok” to save your changes.
If you get an error trying to save, your target line may not have the correct format. Please try step 5 again.
7. Double click “Guild Wars 2 Port Test” and try connecting again.”

This is beyond annoying. I’ve been playing since the headstart, and I’ve never encountered this problem until recently. A few days ago when I tried playing (I hadn’t played in about two or three weeks prior to this), I started to get the error message. At first it happened every 30 minutes or so, so I was like “Aight, I can handle this. It’s no biggie”.
But now? I don’t even last 45 seconds in the game before getting disconnected.
I tried the port thing and I failed to see any improvement.
I’m super irritated now. I was looking forward to actually start playing the game once again, but I clearly can’t even do that =.=
