@EA_Aljo
Just like @baguscool I have contacted my ISP (WhizComms, Singapore, 1GB fibre), they checked the connection and there is nothing wrong. They also confirmed that they do not do any filtering or throttling of the connection.
The problem is not with the ISP. Look at the facts: in these active threads about the same problem (also see https://answers.ea.com/t5/Technical-Issues/BF2042-unable-to-connect/m-p/12280915 and https://answers.ea.com/t5/Technical-Issues/Battlefield-2042-persistence-data-problem/m-p/12280918) you see many users with the exact same problem from different countries, so it can't be an ISP problem. Mostly the users are from South East Asia (Malaysia, Indonesia, Singapore, Hong Kong).
As I have pointed out previously, it's not an either or, sometimes I am able to connect, other times I am not. Mostly when I am able to connect, there is lag, rubberbanding and package loss.
I have played this game daily for over a year and never hand any connection problems or lag/rubberbanding/package loss. Until Friday 27th January. Then it starting being like I am describing here.
All other services - games, mobile apps, web pages work with no problems. It is only BF2042 that doesn't work.
Based on all of this, you can not just blame the ISP. At the very least you need to give us more to troubleshoot than just saying ask the ISP. We have done that, and there is nothing to report. If you actually want to help us, you need to give us something we can test based on what the game requires. What actually happens when the game is trying to connect to online services? What services does it connect to? Give us server URL's and/or IPs that we or our ISP's can test for.
As I have said before, I believe the problem is related to server capacity. This could also be about connection capacity, i.e. capacity of the internet connection to the servers. We just don't know which part of the connection has the problem because it might be over many hops. But it can't be isolated to the ISP because we don't use the same ISP because we're not even in the same country. If we have more details about what services the game actually uses when establishing the connection to online services, we have a better chance of identifying the problem.
Based on the fact that users have reported not having the same problem with Battlefield titles, I believe the technology used in BF2042 to connect to online services is more sensitive and error prone than it was in previous titles.
This is not a minor problem. If EA/DICE wants future titles to be succesful, you need to solve this problem. I suggest you assign network engineers to work with us on this problem instead of just bouncing the ball back to us every time. I am happy to work directly with your engineers and do any troubleshooting you require on my side. I have the time and the skills.
