3G Internet access

Today, I have completed 3G Internet access services, plugged the network adapter into t400, and changed 3 USB ports. After n times of installation, I still encountered a problem with wireless routing at home, which is a mess, I cannot find any information, but I still need to fix the wireless route first, then uninstall the client, and reinstall the driver and client. I am very skeptical about the 3.1mbps speed displayed on the client, the buffer for using PPLIVE to watch movies is much longer than that for wireless routing (iron's wired network access). It seems that it is enough to watch webpages and listen to songs, after all, 3G is only used to prevent wireless route strikes :).
