 * **Disable autotuning to improve wireless connectivity**

If you're having problems with wireless networking, it may be because the router or WAP is an older one that is compatible with the tuning feature inVista. That happens a lot with public hotspots. If you disable the autotuning feature, you may get better connectivity. Luckily, it's an easy fix: You have to restart Windows to apply the change.
 * 1) Open the command prompt with administrative privileges by right clicking its icon in the Accessories menu and selecting Run As Administrator, or by typing cmd in the Search box and hitting Ctrl+Shift+Enter and responding to the User Account Control dialog box.
 * 2) Type: netsh int tcp set global autotuninglevel=disable
 * 3) Press ENTER
 * 4) You should get a message saying "OK"

Those devices get their address spaces first, and whatever's left over goes to your RAM. For a much more detailed discussion of this problem, see
