Disconnected from Server whilst Playing
One of the more common reasons for getting “Disconnected from Server” is due to out-of-date drivers for the network device you have installed and/or a misconfigured network component. Ensure that you have downloaded the most current drivers available from the manufacturer of your network card. More details on driver updates can be found here:battle.net/support/article/200576
Please also check the 4) Router or Firewall problems section
to ensure that those devices and software are correctly configured for the game. Account sharing
Other programs on your computer or on other computers within the network which use the same internet connection can also cause a disconnection problem.
Please disable or end all other programs within your network that increase the network traffic (e.g. file sharing software, parallel downloads, internet community programs etc.). You can do this by following the following article:battle.net/support/article/200483Problems with only one character
Should a problem occur only with one single character, and normal gameplay is possible with other characters, it is possible that there is a corruption in the game’s cache files. In this case please exit the game, then delete the folders WTF
in your World of Warcraft installation folder, and then restart the game.
If the issue continues, please also log into the same realm with another character and use the red question mark on the toolbar to contact a Game Master about the problem to ask them to investigate if that particular character has become stuck in some way.
Note: In some cases, powering down your router/modem completely for an hour has fixed some single character connection issues. Satellite DSL
Due to the architecture of the connection via satellite, you should expect high latencies and to be routed over foreign countries, which can cause lags and disconnection problems. Furthermore some providers of Satellite DSL block ports used by World of Warcraft. Due to the fact that Satellite DSL software changes hosts and imhosts registrations, you should uninstall this software when temporarily using another internet connection.Advanced Network Options
As World of Warcraft has been updated, more options have been added to tailor the game's network architecture to suit more modern network types. However these options may cause issues with older or less stable network connections.
If you are experiencing disconnections, go to the System options in World of Warcraft, then the Network tab and disable both the Optimize Network for Speed
and Enable IPv6
