Nostalrius Begins - Quality wow vanilla realm (1.12)

Like the title says, I will randomly get disconnected from the server for a few seconds every couple hours. I am always able to immediately log back in after waiting a few seconds. I have disabled my firewall, I am using a wired connection, and my graphics card has up to date drivers. I am using a GeForce GTX 670MX with DirectX 11. I am running WoW as an administrator.

Normally this isn't to much of an issue, but it becomes annoying in instances, and a large inconvenience in Battlegrounds, where a 10 second disconnect kicks me from the BG and gives me a 15 min Deserter debuff.

Does anyone know how to fix this

If you are using any Addons, please remove the folder or backup that folder on another location and try to play again. Also please be sure that your wow folder is clean, might be a problem with anti-cheat detection tool which finds something wrong with your installation.

Try disabling the wireless on your router or switching it to bridge mode. It will make your connection less secure, but might work.

Found a way to make this reproducible. If I buy Essence of Agony too quickly from the poison vendor, I will get a similar "Disconnected from server" crash.

But it can also happen if I'm doing absolutely nothing.

I don't think it's my addons. I was getting these crashes before I used any

Same problem here.

I'm French (Free Telecom) and have this issue each hours. Each time i got a small rollback this is really annoying

I have 15ms latency, i don't understand how i can be disconnected like that with my good connection.
