Details:

During normal gameplay, throughout multiple times in a day, and in various settings in Eorzea such as in town or out alone in the field, I will randomly get a red R0 at the top right of my screen. This is accompanied by everything in my screen coming to a stop, both PCs and NPCs.

This has occurred with multiple computers at my home, including my desktop and two different laptops. I suspect it's a connectivity issue but have no idea how to attempt to correct it as this is the only game where I seem to have R0 lag spikes. I don't recall ever getting R0 on FFXI, don't disconnect or freeze on World of Warcraft, Diablo 2, or from playing League of Legends.

On additional testing with Pingtest and Speedtest, I have noted that my download speed and upload speeds average 15 mbps and 1 mbps respectively, with 0% packet loss on several trials.

I cannot replicate the connectivity issues with my home connection on any other application or game besides FFXIV.

Steps:

1. Log in, play FFXIV, and for most of the time everything is going fine. I get smooth FPS and green connection for probably 90% of the game experience.

2. Randomly, while in town, or out in field areas such as Camp Horizon, Cassieopeia Hollow, or Coerthas, the green S & R icon at the top right of my screen will turn red and say R0. This occurs while soloing, or in small or large parties, or in town.

3. The above occurs frequently throughout the day at seemingly random intervals and last for 15-30 seconds or longer. Afterwards, the game will come back to life and I will see a green connection again. R0 spikes can occur again soon after or be delayed between occurances.

Date & Time: October 6 2011 till current day 10/14/11

Frequency: 3 or 4 occurences every 15 minutes. Last for about 15-30 seconds then everything is good again until the next incidence. Sometimes can go for long periods without a R0 spike.

Platform: PC

PC Manufacturer & Model Number: Incident has occurred on multiple systems. Will list my primary system specs.

Cyberpower Custom Desktop

OS: Windows 7
Graphics Card: Nvidia GeForce 560 Ti 2Gb
ISP: Cox
Type of Internet Connection: Cable

Additional Notes:
*During an R0 lag spike, I can still move my character
*I get very good FPS at all times, even in crowded cities. While R0'ing I maintain good FPS when I move around and spin the camera around, it's just that everything else in the world stops moving until I get a green connection back.
*Windows firewall is disabled and I'm on a netgear router that was purchased 2 years ago.

Thank you for any assistance or advice you can provide. =)
