[Klonoa]

well i contacted SE and this is what i was told

Agent Jordan R: Hello and thank you for contacting SQUARE ENIX Customer Support. Just a few moments while I review your question, please.
Agent Jordan R: Hello..... it seems you are having some technical difficulties, particularly with disconnection. Would you mind if I transfer you over to a tech agent for further troubleshooting?
You: its only having problems with the login server. but yes if you need to transfer me that is fine
Agent Jordan R: Ok. Just a moment, please.
Agent Jordan R has disconnected.
Agent Adam E: Hello and thank you for contacting SQUARE ENIX Customer Support. Just a few moments while I review your question, please.
Agent Adam E: While I look over your ticket information, may I have your first name please?
You: Benjamin
Agent Adam E: Thank you Benjamin. I understand you are having trouble with the 2002 error?
You: yes. and we have 5 accounts in this house and all of them get the same error
Agent Adam E: Are you on a wired or wireless connection?
You: wireless
Agent Adam E: And are all attempts with all accounts on wireless?
You: yes. i have also tried a different router. we randomly got 90000 error and then after that 2002 every time
Agent Adam E: Is it possible to plug directly in to the modem/router?
You: not with how far away it is. i have checked all setting or router and i have reset it to the defaults to make sure.
Agent Adam E: And what type of connection do you have (DSL, Cable, Satellite, etc) and how is your Internet Service Provider?
You: DSL and we have had the same provider for years. never had any issues before
You: other than the internet is kinda slow. pretty much just fast enough to play lol
Agent Adam E: Then the best option to try right now will be as follows:
Unplug the modem/router and leave it off for 10-15 minutes
Contact your ISP, and ask them to open and forward the port ranges I am about to give you.
Agent Adam E: The port ranges are
▼TCP
54992～54994,55006～55007,55021～55040
You: so that is all you can tell me is that it has to be on my end? there are 30 plus players on the forums with the same problem
Agent Adam E: And almost every single time, it turns out to be an issue with the ports not being opened.
You: so what makes them close after a year. because it was working fine like 3 days ago
Agent Adam E: Another thing is that we do not really support wireless connections, since they are not stable enough.
Agent Adam E: If the ISP makes any changes in their system, it could close ports.
Agent Adam E: This is the first step and easiest way to fix the issue, if it does not work, contact us back and we will explore other options.
You: and wait another hour or close to it to get someone

ok i figured mine out. here is something to check. log into your modem and make sure that your firewall on you modem is set to off
