Those with periodic error 90000: do you have a Realtek network adapter?

FIXED:

After disconnecting with error 90k on an hourly basis and trying everything else, it looks like the culprit was automatic updates setting on Windows Update (which I now have scheduled for a certain time) or the automatic updates / running at startup of Easy Tune 6, my motherboard's chipset program. One or the other, but probably ET6. Since changing the Windows Update setting and changing the ET6 setting and closing it, I've had the game connected for about 10 hours straight with no disconnects while testing the connection.

I'm trying to narrow down the cause of frequent disconnects. I typically disconnect once about every hour or two. I see people disconnecting in instances and other areas all the time, so I know that it's not just me having this problem. There is no lag involved in my disconnections. I'm playing fine and then I instantly disconnect. No warning, just disconnect instantly.

What I've noticed is that people are reporting that one PC / laptop in their house has issues and another does not. Based on anecdotal evidence from people and my own testing, I think this might be a hardware issue. The PC I have that's disconnecting has a Realtek network adapter while my old PC which can barely run the game thus far hasn't disconnected, and it uses an Nvidia network adapter. This seems to be the only notable difference that I can discern between the two computers that would affect the game. I also have the PS3 version of the game and do not recall having error 90k / disconnect problems before playing the PC version on my gaming computer.

I'm thinking a possible workaround would be to buy an USB ethernet adapter, which I'll try tomorrow. The drivers and such on my Realtek are up to date.

If you're having error 90000 / disconnections, what network adapter are you using?

Here are things that I've tried:

• Swapped out ethernet cables
• Power cycled modem and router
• changed which port in the back of router ethernet cable plugged into
• bypassed router entirely and connected directly to modem
• opened necessary ports
• made sure firewall allowed FF14
• disable firewall (the same one that works with FF14 on the other PC) and tried default Windows firewall
• changed large send offload settings
• tried VPN / tunneling services
• changed account password out of paranoia that someone was attempting to log on my account, thus kicking me from the game
• verified with my local ISP that there is no throttling (I know the owner real well, so I'm not getting lied to here)
• etc.

I'm not sure what else that I could try, and the only difference that I can see between the PS3 and old PC vs. the gaming PC would be the network adapter. It could be that it's faulty (but it works fine for everything else and for every other game), or it could just be that Realtek adapters have an issue with this game. Anyway, I will buy an USB ethernet adapter tomorrow and test if that resolves the issue for me.
