This post is regarding an NIC controller issue on new motherboard utilizing Nvidia nForce4 and 4 Ultra. I have also seen this affect some of the nForce3 chipsets as well. I've been trying desperately to solve the issue and have been reading posts and tech forums for hours. Hopefully this might shine some light onto the problem if any of you are experiencing the same issue as I am.
Basically here is my current config:
----------------------------------------
Asus A8N-E nForce4 Ultra mobo
AMD64 3700+
2GB DDR PC3200
GeForce 6800GS 256MB - (PCI Express)
The problem seems to be originating from the motherboard, mainly the chipset. I know some guild members have had some issues, and as I've done some research, I found enormous amounts of people have been experiencing the same issues that I have involving disconnecting and the wonderful Error #132.
Pre 1.9, the crit erroring was irregular so I paid no attention to it really, as some days I wouldn't error once, and other days it would a few times.
Now that 1.9 is live, I am experiencing huge issues where I am disconnecting consistantly every 30 seconds, to 5 minutes. Most of the motherboards experiencing the problem is due to the NIC. On my particular motherboard as is the case with many others of this family, it comes with the nForce4 NIC Driver as well as the Marvell NIC driver. If you are using the nForce4 driver, basically there is a huge application problem with the Nvidia Firewall that will install itself unless you manually tell it not to when you are loading all the drivers on to your computer at install. I'm not sure the exact application error, but it seems to the cause of the disconnects and critical errors. Apparently disabling the Nvidia Firewall is not sufficient, it must be completely uninstalled to remedy the problem. The Marvell driver one is supposabley more stable so trying that one might be a good idea.
This won't fix every single case, but its something I found interesting and am hoping will fix my problem. Unfortunately, the Nvidia Firewall program doesn't install a standalone uninstall program with the setup, you must use the cd you installed the drivers originally from to get rid of it. My problem is that I don't have access to my cd at the current time

so I am trying to find another way around it without having to go get it (Left it at my school apartment). I'm kinda noob with this stuff, but hopefully this might shed some light onto your disconnect problems, this was one of the threads I found that I got a lot of the information from if you want to check it out.

Edit:
Like I said I'm a bit of a noob, and I missed an uninstall option. If any of you guys are trying to uninstall your Nvidia Firewall...
Go to Control Panel -> Add/Remove Programs -> Nvidia Forceware Network Access Manager
Choose Modify and uncheck Firewall, restart and hopefully that will solve the problem.
