Suggestions we have
===================
1 a. Check to make sure you have properly configured or turned off any of the following:
Firewall software, Antivirus Software, Parental-Controls, pop-up blocker software, Routers, Proxy Servers, NAT Servers, Internet Connection Sharing services.

1 b. If you are using any kind of software/hardware Internet Sharing service/device the following ports need INCOMING access to your PC. TCP 25, 80, 110, 443 and 50000 - 65535, UDP 53, and 50000 - 65535, also check to make sure that the ports mentioned are not blocked by your ISP for INCOMING access. Proper configuration of any of the above items mentioned should be done by following the instructions in the software /hardware manual or calling the manufacturer's technical support.

2. We recommend turning off any background programs, this should be done using msconfig startup tab:
How-To: Turn off background programs using msconfig.
(Win 98/ME) - Open the start menu and select run, type msconfig and press ok. Select the startup tab and
uncheck everything except for SYSTRAY and scan registry.
(Win 2K/XP) - Open the start menu and select run, type msconfig and press ok. Select the startup tab and choose Disable All.

3. If you are receiving the error FFXI - 3113 - Protocol Timeout Error, ensure that Client for Microsoft Networks is installed in your Windows network properties. If it is installed, you may want to try uninstalling and reinstalling it.

4. If you have had a software firewall program called Zone Alarm by Zone Labs installed on your computer at any point in time - even if it is uninstalled now, you need to reinstall it, turn it on, configure it to allow PlayOnline to access the internet, and leave it active.

Please take note of the following FAQs
======================================
* Proxy servers, and satellite connections do not work correctly with FINAL FANTASY XI.

* You may need to set up a web browser for your PC if you are having trouble accessing PlayOnline.com.
For more information, please refer to the appropriate vendor's instruction manual.

* Your router may require that you use a PC to configure your network settings.
For more information about how to configure your network settings, please refer to the instruction manual that came with your router or contact the manufacturer directly.

* If your Internet Service Provider (ISP) specifies a DNS server, you need to make sure to configure your settings to allow packets to pass through UDP Port 53 as well.
For more information, please refer to the instruction manual for your router or the information provided by your ISP.
