Frequent R0 in-game

[Eyn]

Details & Steps:
It begins on 28th September 2012. For a week, occasionally I faced R0 in-game. After a week, R0 becomes very frequent. R0 is very obvious during JP peak hours, especially when joining raids and crafting.

At first, I called my ISP regarding this R0 issue. Technicians were sent twice to my home. They checked on the condition and quality of my internet cable, and changed port. Nothing is solved.

By the third time technician was sent to my home, I am advised to install a freeware to trace and monitor my ping. Therefore, I begin my ping to 202.67.51.114. My results are as follows:


(Time is based on GMT+8)

From screenshot above, it is known that ping is lost frequently. In order to detect where actually goes wrong, further test is done and the result is as follows:


(Time is based on GMT+8; Red vertical rectangles at bottom indicates 100% packet loss)

From the screenshot above, packet losses occur at IP 219.117.X.X.

By searching at http://tools.whois.net/whoisbyip/, it is found that something is happening at Square Enix's network?

I have port-forwarded and enabled UPnP at router.
Ports enabled are:
TCP 54992 to 55551
UDP 443, 55296 to 55551
(Ports are re-confirmed open by using a freeware.)

I notice R0 starts at the end of the official subscription dateline.
Servers have no maintenance for quite a while now, too.

In need of assistance regarding this issue. Thanks.

I'm having the same issue though i'm over in Texas, what server are you on? edit: didn't notice the world next to your name. Is this happening in all zones or any in particular? Its been happening pretty bad when i try farming hats.

I just started having this issue as well. Have not been able to play more than 10-20 mins at a time for last 3 days. Nothing has changed on my System. I have done no updates in last 3 days. Drivers are up to date. My internet seems to be working very well for everything else Netflix etc.

Issue resolved for me and many others. I had DC occurring from 10 minutes to 1 hour after each login. Seemingly on some days and not others, making it difficult to find the cause. After a month of researching amongst trial and error this is the solution that has kept me online indefinitely.

The Culprit: "The Simple Service Discovery Protocol (SSDP) is a network protocol based on the Internet Protocol Suite for advertisement and discovery of network services and presence information."

Solution: Start > search: services.msc > SSDP Discovery: properties > startup type: disabled. Reboot.

This service is not necessary for UPnP operations and will randomly start up, completely maxing out your bandwith and latency until FFXIV begins to lose packets and inevitably disconnects.

I solved my problem by having the right IP address (provided by my ISP).
How does IP addresses affect packet loss at Japan siide? I guess Japan blocks/throttles the IP addresses?
