There are currently about 2 dozen threads on this network connectivity/R0/Lag/Connection refused issue.
Square-Enix stated that it most likely is a networking issue, so in the best interest of giving people good, clean information, here's some steps to recycle your network WITHOUT being uber-tech-savvy about it.
Step 1: Verifying your IP.
If the IP reset is what clears this issue, let's find out what that is, shall we?
-In Windows XP, click Start, then run.
*In Vista, just type cmd in the Search box
-Type in cmd
-Hit Ok
-In the command prompt window (That black thing that just camp up) type in ipconfig
Copy down the IP address and the Default Gateway. The Gateway is the IP address of what actually hooks you into the internet (The router's IP, modem's IP or server's IP it uses for you). Keep these numbers for reference.
Step 2: Determining your network
This is the easiest part. How are you connecting? That can be broken down into two neat categories:
- High Speed aka Broadband
- Dial-up
If you're on Dial-up, your journey ends here. Your IP address should be dynamically assigned unless you're one of the very few that actually uses a dial-up router (Yes, they do exist, and in wireless versions too). If you're one of those... check out the router section later. If you cannot connect via Dial-up, call your ISP or call Square-Enix to verify there's nothing unique about your situation.
Now, all you high speed types, time to determine HOW you connect.
- Through Telephone lines
- Through Cable
- Through Satellite
- Through Fibre Optic
Next, verify your "Network Topology", or "Where the heck all these wires go?!?"
- Do you have a modem inside your home for the connection or do you jack directly into a wall?
- Do you have more than one computer sharing this connnection via a router?
Once you have determined this, we can move on. I'll start with routers and networking first.
If you have a router, remove it from the system. Connect your system directly to modem/walljack and see if it resolves your issues. If it does, your issue is your router. As was previously stated, changing the MAC address, or the physical network identification of your device, can fix this. Call your router company on how to do this, or check out their website. The why behind this is that your ISP is holding an IP Address that is associated with that MAC address. Everytime you connect it, it will try to give you that address. Calling your ISP to release any MAC addresses they have will also clear this.

Ok, if your issue is resovled, Congratulations! Otherwise, slog onwards with me.
Right, so we've gotten the direct connect to the modem, but what gives! We still cannot connect. Now we have to look at the modem. These days, a lot of modems are in and of themselves routers! But you can't disconnect it, or you have no internet connection. And likely you don't exactly have one to spare lying around.
So there are two ways to go about this:
- Contact your ISP for an IP reset
- Power cycle the modem
Since I can't tell you how to argue your way through the ISP...
Remove the power plug from the modem. Go have lunch. I'm totally serious. Leave it unplugged for an extended period of time so that your ISP releases your IP address on its own. A great way is to do this when you go to bed, and replug it in the morning. If you have fibre to your door or a modem you can't unplug... Call your ISP. No other choice.
So, how did it go? Still nothing? Onto the dreaded Step 3.
Step 3: Fooling with your software
Ok, so the first thing to do at this step, get your IP addy again.
-In Windows XP, click Start, then run.
*In Vista, just type cmd in the Search box
-Type in cmd
-Hit Ok
-In the command prompt window (That black thing that just camp up) type in ipconfig
Is it the same? No? Good. It shouldn't be by this time. So now it's a farked up setting on your system. Time to start resetting stuff. NONONONO!!! Put your OS CD down... we aren't formatting. Just set it down and back away slowly...
Ok, here's the series of commands you need to enter:
At the command prompt (see above if you forgot how to get there) enter this:
winver
Check the window that comes up. If it says that you are running Service Pack 2(SP2), enter this command:
netsh int ip reset ffxilog.txt
Service Pack 1(SP1), follow this:
EDIT: PRINT THESE INSTRUCTIONS OR WRITE THEM DOWN! This will temporarily sever your internet connection!
Click Start and then click Run.
The Run window appears.
Type regedit and click OK.
The Registry Editor window appears.
Click the "+" to the left of the following keys:
HKEY_LOCAL_MACHINE
SYSTEM
CurrentControlSet
Services
Here we will delete the keys associated with your Winsock
-Scroll down to locate the Winsock folder.
-Right-click the Winsock folder and then click Export.
-The Export Registry File appears.
-Save the file in the Desktop as Winsock.reg. This backs up the key.
-Right-click Winsock and click Delete.
-The Confirm Key Delete window appears.
-Click Yes.
-Right-click Winsock2 and then click Export.
-The Export Registry File appears.
-Save the file in Desktop as Winsock2.reg. This backs up the key.
-Right-click Winsock2 and then click Delete.
-The Confirm Key Delete window appears.
-Click Yes.
Now, for either of these, restart your computer.
Service Pack 2(SP2): You're done for now.
Service Pack 1(SP1): Follow this:
-Click Start, and then Control Panel.
-The Control Panel window appears.
-Double-click the Network Connections icon.
-The list of available connections is displayed.
-Right-click Local Area Connection and left-click Properties.
-The Network Connection Properties window appears.
-On the General tab, click Install.
-The Select Network Component Type window appears.
-Click Protocol, then click Add.
-The Select Network Protocol window appears.
-Click Have Disk.
-The Install From Disk window appears.
-Type C:\Windows\INF and then click OK.
-Click Microsoft, then click Internet Protocol (TCP/IP) and click OK.
-The Network Connection Properties window appears.
-Click Close.
-Restart the system.
-Click Start, then click Run.
-Type netsh int ip reset ffxilog.txt in the Run line and click OK
WHEW! Now go update to SP2 so you never have to do THAT again.
Try now. Still no good? Let's get back into command, and we'll give her one more go:
Enter in:
ipconfig /flushDNS
ipconfig /release
ipconfig /renew
ipconfig /registerDNS
I know some of that might be overkill, but that's everything internet related I can even THINK might be related.
Try now. no go?
Well, that's when you call your ISP/SE again or the vendor of your computer and hope you get someone nice to try something more.
