To begin with,
restart your PC and your router. Make sure you wait 10 seconds before you turn the router back on. Also, you will need to assure that your internet connection has a good ping. The lower the better. Take a
ping test. 100ms is an excellent ping but 10ms which is a hundredth of a second is almost instantaneous. If you are getting anything higher than 100ms it can be noticeable in Minecraft and if you are constantly getting anything higher than 1000ms then you should consider contacting your internet provider. If you are getting kicked from servers resulting in timeout errors then it’s most likely your ping.
If your ping is fine, take a look at these suggestions:
- Is your Minecraft client the same as the server?
- Is your network interface card driver up-to-date? A simple update may fix the most ambiguous problems. If you aren’t familiar with this you can visit this page which will guide you through the process of updating your NIC driver.
- Disable unneeded network interfaces. If you don’t need Hamachi and Virtual Box you should disable them. They can slow down or interfere with your connection.
- Try disabling your firewall and any antivirus software as they could interfere with the connection as well. However, you should firstly consider the risks in doing this.
- Reinstall a fresh version of Minecraft if you haven’t yet. Make sure you save all your worlds first.
- Is java up-to-date? This is essential for Minecraft and can fix a wide range of problems - non multiplayer related as well.
- Allocate more RAM to Minecraft. This solution has been deemed to fix socket exceptions. This tutorial will explain how to do it.
- If the problem started to appear right after an automatic or manual system update you should be able to revert it to a previous restore point.
As for LAN multiplayer, you have to assure that all the users in the network have a different local IP address. Usually DHCP solves the problem of assigning each device with a unique address in a network. In Windows, DHCP should be enabled by default. If the computer has a static IP assigned to it inside a DHCP based network, it’s best enabling DHCP to avoid any conflicts. However, in some cases, a DHCP server may mistakenly create IP conflicts. To fix an IP conflict with DHCP enabled you can reset your computer or in Windows type
ipconfig /release then
ipconfog /renew through the command prompt.
You can also avoid conflicts and DHCP by assigning each computer a unique static IP address. It’s painstakingly time consuming but you only have to do it once.
