Analysis And Optimization Suggestions On The Reasons For Frequent Disconnections Of Korean Servers In Swordsman World

1.

detect network delay and packet loss (the first step, locate the problem)

operation points: open a command prompt on windows and run ping -t <server ip or domain name> to observe delay fluctuations and packet loss rates; run tracert <server ip> or pathping <server ip> to locate which hop has packet loss or high latency. mac/linux use ping, traceroute or mtr. record screenshots or copies of the data for at least 1-2 minutes as evidence for subsequent comparison and feedback.

2.

local network troubleshooting (wired/wireless and device check)

operation steps: 1) prioritize the use of wired (lan) connections to eliminate problems caused by unstable wi-fi; 2) replace network cables, switching interfaces or router ports, and test whether different ports and network cables are improved; 3) close other bandwidth-consuming download/synchronization programs (such as bt, cloud synchronization); 4) temporarily close firewall/security software for comparison (windows defender or third-party anti-virus software) to confirm whether it is interference from local software.

3.

router and isp level optimization

specific operations: 1) restart the router and update the firmware to the latest version; 2) enable qos (quality of service) in the router, prioritize bandwidth allocation for game traffic or devices, and fill in the port or device mac address of jx world; 3) contact the isp to confirm whether there is a fault or speed limit on the route to south korea, and ask to check the bgp path or intermediate packet loss; 4) if the isp route is not good, try changing the dns to 1.1.1.1 or 8.8.8.8 to try to improve the resolution speed.

4.

mtu and tcp tuning (solve fragmentation or connection reset)

practical steps: 1) test mtu: use ping -f -l 1472 <server ip> in windows and gradually reduce the value until no fragmentation occurs, mtu=size+28; 2) adjust the mtu of the router or network card to a safe value obtained by the test (such as 1500 to 1492 or 1472); 3) if using a vpn, test the mtu/fragmentation settings of the vpn at the same time; 4) enable/disable tcp offload in the advanced network adapter settings to test stability differences.

5.

try a temporary solution for a stable connection: vpn and game accelerator

operation suggestions: 1) choose a paid korean node vpn or game accelerator with a good reputation, and give priority to the lowest latency node; 2) record the ping/traceroute comparison between not using and using the vpn during the test; 3) if the vpn improves significantly, it means there is a problem with the isp or intermediate route, which can be used as a short-term solution and feedback to the isp/game side; 4) pay attention to choosing an accelerator that supports udp transparent transmission and fragmentation optimization, and turn off the cpu usage caused by over-allocating encryption.

6.

collect client and server logs and report them (communicate with officials)

operation process: 1) save the game client log when disconnected (check the log file in the game installation directory or enable debugging mode); 2) synchronously attach the text results of ping/traceroute/pathping with timestamps, isp information, and router operation records; 3) contact the game customer service to provide the above files and describe the steps to reproduce (for example: disconnected after entering copy x, disconnected at peak times during a certain time period); 4) ask customer service to report the problem to operation and maintenance or the korean computer room, and ask for the work order number for follow-up.

7.

common misunderstandings and long-term optimization plans

notes: 1) do not frequently reinstall the system or reset the router as the first choice, locate the problem first; 2) if the connection often drops during the same time period, consider it related to game peaks and isp traffic scheduling, record the disconnection time period and check with neighbors or players in the same area; 3) long-term solutions include changing to a more stable broadband operator, applying for a direct connection/dedicated line, or negotiating with the game party to add a local relay node.

q: how can i quickly determine whether it is a local network problem or a korean server problem?

q: how can i quickly determine whether it is a local network problem or a korean server problem? answer: do two things when you are offline: 1) ping/tracert the target server locally and save the results. if there is packet loss on the first hop, it may be a local or router problem; 2) use mobile phone data (4g/5g) or a friend to connect to the same server through different networks to test. if the mobile phone network is normal but the home broadband is not, it may be a local/isp problem; if multiple networks are offline, it is most likely a server-side or korean link failure.

9.

q: which should i try first, adjusting the mtu or using a vpn?

q: which should i try first, adjusting the mtu or using a vpn? answer: it is recommended to check and adjust the mtu first (it can be quickly tested locally at no cost). if the mtu adjustment is ineffective, try vpn as a temporary solution. if the vpn becomes significantly stable immediately, it indicates a problem with the intermediate routing or isp, and the results should be reported to the isp and game customer service as evidence.

10.

q: what key information is needed when submitting questions to game officials?

q: what key information is needed when submitting questions to game officials? answer: provide the disconnection time range, server name, complete client log, ping/traceroute/pathping text, used isp and local ip segment, whether to use vpn and its node, reproduction steps and screenshots/videos. complete information can greatly speed up problem location and repair.
