频繁掉线的试一下
言归正传，其实一开始我也碰到过这问题，看到了iamaperson的帖子其实也是将信将疑的，毕竟暴雪的名头太大，网络兼容性不会这么差吧？其实按照TCP协议来说（前几天我专门分析了魔兽的所有服务器的IP和端口，工作需要，发现走的全是TCP协议，端口3724，现在我有上海和北京96组服务器的所有IP和部分验证服务器IP，估计每个地区有5-10台的验证服务器，不过9C请放心，我的工作不是做外挂，也没去分析魔兽协议里的内容，我的工作对你完全没影响），网卡的一些设置确实可能会产生影响，还是那句话，感觉暴雪不应该会出现网络兼容性的问题（其实我对TCP不是非常精通，至少没到对每个TCP的OPTION都能背出来的地步，本人对UDP还是比较熟悉的，视、音频打包、拆包，穿NAT、防火墙--我的工作之一），所以觉得可能性不大，但确实觉得iamaperson的精神是需要发扬的。
直到昨天，我一个朋友碰到这个问题，被搞得非常头痛，所以我帮他去找相关的资料,在暴雪的Support上就写明了相关的问题[ http://forums.worldofwarcraft.com/thread.aspx?fn=wow-tech-support&t=274985&p=1&tmp=1#post274985 ]
里面很明确有段话
Network card related - Some network adapters may require a driver update or duplex change to stabilize connectivity. Some models include; Realtek RTL 8139/69 series, Intel Pro series, Broadcom 440 series, Marvell Yukon Series, Via Rhine series, and the nVidia nForce series. Please visit the link below for assistance in making these changes.
如果你的网卡是Realtek RTL 8139/69系列、Intel Pro系列、Broadcom 440系列、Marvell Yukon系列、Via Rhine系列、nVidia nForce系列，那么恭喜你，你很有可能出这种问题。当然这也和你的网络情况有关，我两个朋友的笔记本一抹一样，都Intel Pro 100的网卡，但其中一个有问题，一个没问题，究其原应应该就是和网络有关（一个网通、一个ADSL）。也有人说服务人多地时候容易出，这也有可能，毕竟服务器忙得时候出错的几率大（看下面的checksum offload选项），但到底是什么原因，不要问我，TCP开了那些Option，我光抓包不是那么容易能分析出来的（至少会很累），暴雪，就这点来说，你太让大家失望了，这么多游戏没问题，就你出问题，这几块可是主流网卡阿？
解决方法也说了
There are several drivers that, if out-of-date, could cause issues for broadband users. If you need more help in locating drivers for your hardware or finding the settings listed, please contact the hardware manufacturer or a qualified technician. If you access the internet through an external broadband modem, be sure you have the latest firmware and drivers available for your modem. If your computer connects to the modem via USB, be sure you have the latest drivers for your motherboard or your USB PCI card. If your computer onnects to the modem via Ethernet, be sure that your network card has the latest drivers installed. if you have a power management tab in our network card properties, click it and unselect the "allow the computer to turn off this device to save power" if selected. Checksum offloading. To turn the checksum offloading off go to start > control panel > click network connections > right click on your active etwork connection profile and select properties > then click the configure utton at the top > under 'CHECKSUM OFFLOAD' (if listed) change it to 'DISABLED'. This will disconnect you from the internet for a brief moment. You should automatically reconnect, if not restart your machine.
You can also try changing the Speed/Duplex to Force 100 Full Duplex. This has shown to fix these types of issues as well. To
do this, go into your computer properties, and then into your device manager. Locate your network card, and go into the
properties for it. click on the advanced tab, and you should see a list of items. One of them should be Speed/duplex settings.
Change this to Force base 100 Full duplex. If you have an older router or hub you may need to use base 10 full duplex.
