WotLK Disconnections problems on WOTLK

[Spaceman974]

Hi, i have a problem with my game (or my computer..)

I came back after 2 years (I played on another server before and I had no problem)
When i am playing WOTLK i get disconected around 15 or 30 minutes after i log in, then i get kicked to login screen.
I dont know what exactly the problem so i try delete cache, redownload client.....but i still have the same problem..
A friend of mine has no problem, so..

Someone can help me? :/

Maybe you lose your wifi connection??

if you have connection issues personally such as bad connection with your internet or wifi etc and it drops out just a single time, then that can be enough to disconnect you. The thing is also you cant compare two servers connection due to the providers can variate alot that means wherever the servers are hosted is usually very different from eachother causing very different results.

In general I have a good conexion, but I have this problem for the first time and only on WOW. On other games PC or PS4 I do not have this problem.
Maybe you're right, but how can I fix this problem?
