The full WoW 1.12.1 client weighs 5–6 GB, and on a slow connection the download can drag on. Let's look at why the speed is low and how to raise it.

Common causes of slow downloads

Cause	Symptom	Fix
Few seeds	Speed jumps, stalls near zero	Download during active hours, wait for seeds
Torrent cap	Speed stuck at a flat number	Remove the limit in settings
Closed port	"No incoming", slow	Open the port in firewall and router
ISP throttling	Direct link faster than torrent	Use a mirror
Weak Wi-Fi	Unstable speed	Connect via cable

Method 1. Tune your torrent client

Remove the download speed limit in settings (set "unlimited").
Increase the number of connections and slots.
Allow the program through Windows Firewall and, if possible, open its port on the router (port forwarding).
Don't run many other downloads at once.

See the download via torrent guide for details.

Method 2. Change the source

If the torrent stays slow, try a direct link or another mirror from the download page. Some ISPs throttle torrent traffic while direct HTTP downloads run at full speed.

Method 3. Check your environment

Temporarily stop other downloads, streaming and system updates.
Connect to the router by cable instead of Wi-Fi for steadier speed.
Make sure the antivirus isn't scanning every chunk on the fly (you can pause it briefly).

After downloading

Once the client is downloaded, be sure to verify file integrity, then move on to installation. If in-game latency is high after install, that's a different topic — see high latency and lag.

FAQ

Why is the WoW client downloading so slowly?

Most often it's few seeds in the torrent, a speed cap in the program's settings, a closed port, or the ISP throttling torrent traffic. Each cause can be fixed.

How do I speed up a torrent download?

Remove speed limits in the client, open the port in your firewall and router, and download during active hours when there are more seeds. Switching to qBittorrent sometimes helps.

What if the torrent won't download at all?

Check whether an antivirus or ISP is blocking the traffic, try a different torrent client, or use a direct mirror link from the download page.
