Minecraft – Connectivity Issues in Minecraft – Desyncing Often and Constant Spikes

minecraft-java-edition

On any server I play on I am constantly experiencing lag related issues such as:

  • Desyncing from server (server world not in sync with player)
  • Lag related spikes every minute at least (spikes can last from 1 second all the way to 15)

I have had no problems on my previous laptop I used to play Minecraft on, and my brother can be on the exact server using the exact same internet and does not have these issues. This has been an issue ever since I built a new gaming computer. Currently I'm using an old USB wireless adapter to allow me to connect via WIFI to my internet. I'm not even sure if this device is to blame, though it could be.

I performed 100 ping requests to Google.ca to see if I had any packet loss, and there was none. I also did a speed test and it reported the usual speed I'd get from other computers on my network.

I don't have any of these issues in any other games, so I'm really confused at howto go about trouble shooting this issue, and how I should resolve it. Any help would be appreciated!

Edit: I just tested doing 1000 pings to google.ca instead of only 100 like I did before and here are the results:

Ping statistics for 173.194.43.87:
    Packets: Sent = 1000, Received = 967, Lost = 33 (3% loss),
Approximate round trip times in milli-seconds:
    Minimum = 10ms, Maximum = 328ms, Average = 15ms

The "ever since I built my new gaming computer" is cluing me to issues with your wifi adapter. Old adapters don't particularly have (good) drivers that work well in newer versions of Windows.

Depending on the game you play, you could potentially experience the same issue as well. Minecraft is very sensitive to latency. Other games compensate by things like motion prediction and other things. Minecraft is just Java + UDP ...that's it.

A test would be to ping /t minecraft.server.ip and connect to the server and attempt to play. If you see drops/spikes, then it's your adapter not able to keep up. However, it's also possible that pinging won't do much since it's a different protocol.
