For those of you who already know the technical issues surrounding port forwarding this will be old hat.  But we recently had a guy comment that his 1.5 Mb connection was taking days to download patches.  So for you folks who are having serious downloading issues we thought it would be good to cover some basics and give you links to resources that will help you get your download speeds up to par with your connection.

Unless you are on dial-up, you should be able to grab patches and even full downloads in under and hour or two if you have your network ports properly configured.  In other words, if you are on any sort of DSL or Cable connection, problems with your download speed in relation to WoW stuff is not a matter of your connection, but something on your machine.

Now, we’re not going to be able to tell you exactly how to do this for Mac machines since I don’t currently have one to test with, but I may have to grab one and do an update for those later.

The first thing you need to do is figure out what you’re trying to fix.  Most people will get the message “Your computer appears to be behind a firewall.”  If you are getting any other message, just check out the link below to find the specific message you are getting from the Blizz Technical Support FAQ page.

If you are getting this next specific message, you can use the link below for slow download speeds.  Most of the time slow speeds will be due to two factors that you can fix pretty easily once you know what to do.

In both of the scenarios we will deal with below, the problem is normally that the Blizz servers are having trouble talking to your system because something is in the way.  The two problem areas are in firewalls and routers.  In order to give Blizzard clean access to your computer you will need to make a path for them by opening some specific ports so that communication between your machine and Blizz doesn’t have something clogging up the process.

A big portion of the time, you windows users will be able to just open up ports on the internal Windows Firewall and that should do the trick.  Now, if you get the message about “it appears you are behind a firewall” don’t make the mistake of thinking that turning the firewall OFF will fix this.  Actually, turning the firewall off will usually make it worse, since it puts your entire internal network into the internet equivalent of safe mode.  Instead of only restricting certain things the way the firewall was designed to do, it will just restrict everything.  So turning it off won’t do you any good.

It’s really simple to open ports for WoW and anything else, you can check out the article at Blizzard here:

The other place you can get all gummed up is in your router if you are using one.  Routers can be particularly tricky because they are all different, there are thousands of them and some have internal firewalls that will also need to be dealt with.  Even though Blizzard has a little bit about working with routers to get ports open, there is a much better place to get the instructions you need.

Portforward.com is a massive database of highly specific information and guides on opening ports in almost any situation.  They have virtually every router ever made in their list, and if you can follow the links like breadcrumbs they will lead you to a pictorial walk-through of opening ports on YOUR router for WoW (and hundreds of other applications).  Talk about highly specific!  They also will help you deal with firewalls and their list of firewalls includes a much longer list than the Blizz page if you can’t find yours there.

By using the tools above you should be able to get the proper ports and port ranges open to allow your downloads to flow much faster.  For those of you who may get Beta invites it’s going to take your downloads from several days to just a few hours.  If you lose your WoW file or something this will save you a ton of download time.  you can see from my download screen I was on pace to be able to download the entire up-to-date game client in about 4 hours (it would probably be less than that, but not bad).

We know this doesn’t have anything to do with playing the game, but you’ll understand why we wanted to cover this in a day or two.  And for everyone who has been living with those 9000 hour downloads this will certainly help you get your patches a ton faster.  The portforward site is a terrific resource - and YES this research site is completly up to date!
