 +====== Disconnects using Windows ======
 +If using Windows, disconnects might occur every few minutes. These are caused by third party firewalls and anti virus software, which might be incompatible to the used PPTP VPN because they disconnect the needed control connection (TCP port 1723) after a short period of time.
 +To resolve this issue, you have to **completely uninstall** the third party firewall or the anti virus software. A deactivation **is not sufficient**. As firewall you can simply use the windows internal firewall. Compatible anti virus software are **AVG Anti-Virus Free** and **AntiVir - Avira Free Antivirus**. If this does not help, only a clean reinstallation of the operating system will get rid of all left over software.
 +As an alternative,​ you can use OpenVPN which is using a different connection approach. An installation guide is available at [[en:​support:​internet:​win:​openvpn|OpenVPN for Windows]]. When using OpenVPN you are free to choose firewall and antivirus software. This protocol might not be as stable as PPTP VPN and the throughput is not as good. You will find a list of advantages and disadvantages on [[en:​support:​internet:​protokoll|OpenVPN and PPTP VPN comparision]].
 +As another option you can also use a [[en:​support:​internet:​wlan_basic|wifi router]]. The router will connect to the login servers and provide Internet connection for all attached devices.
 +Thus you have the following options:
 +  * deinstallation of firewall/​anti virus software (this might not fix the issue)
 +  * clean reinstallation of your computer
 +  * installation of [[en:​support:​internet:​win:​openvpn|OpenVPN]] as VPN protocol
 +  * usage of a [[en:​support:​internet:​wlan_basic|wifi router]]
