  2. Locate and then click the following registry subkey:
    HKLM\SYSTEM\CurrentControlSet\Control\usbstor\VVVVPPPP

Improve Windows 7 networking

leave a comment »

Here’s a set of quick tweaks to adjust Windows 7 networking.  Always backup your computer before performing any tweak.

Open a command prompt as an administrator and type the following -

netsh int tcp set global congestionprovider=ctcp
netsh int tcp set global ecncapability=default
netsh int tcp set global chimney=enabled
netsh int tcp set global dca=enabled
netsh int tcp set global netdma=enabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set heuristics disabled

CTCP or Compound TCP – Improves throughput
ECN-provides routers with an alternate method of communicating network congestion
TCP Chimney Offload – Offloads all TCP processing for a connection to your network adapter
Direct Cache Access (DCA) – or direct cache access allows a network controller to deliever data directly to your cpu cache
NetDMA – enables support for advanced direct memory access.
TCP Autotuning – RWIN auto tuning behavior
Heuristics – Windows 7 has the ability to automatically change its own TCP Window auto-tuning behavior

 

To return to your default settings, go to a command prompt as an administrator and type -

netsh int tcp set heuristics default
netsh int tcp set global chimney=default
netsh int tcp set global autotuninglevel=normal
netsh int tcp set global congestionprovider=default
netsh int tcp set global ecncapability=default
netsh int tcp set global netdma=disable
netsh int tcp set global dca=auto

If you have trouble navigating to sites and time out to Facebook or Microsoft for example, or you want to improve your download speeds -you may need to set your MTU settings -

So what do you set your MTU to?  Normally your MTU is set to 1500.   Every connection is different.  First log into your router if you have one and set it to 1492.  Retry the sites that are timing out.  If this did not work, you may need to set the MTU on your network card.

Use TCPOptimizer for Windows XP, Vista or Windows 7 (easy) -

or you can go to a command prompt (as an administrator with elevated privileges) and type -

netsh interface ipv4 show subinterface

(to see the name of your network Interface – it is important to write down the MTU settings and network interface name at this time)

To set the MTU value to 1492, type the following command at a a command prompt (Note: You MUST substitute the name of your network connection  -

netsh interface ipv4 set subinterface “The Name of Your Connection” mtu=1492 store=persistent

Many users have reported an increase in download and internet speeds after adjusting their MTU to 1492.  This setting may not be the optimal setting everyone.

Broadcom 943xx wireless drivers

leave a comment »

Many laptops and usb wireless devices have the 943xx chipset and drivers are often not written well or are not very good.  Here’s an excellent link to these drivers.   These drivers may say a vendor’s name in the description but this may work.  Always have a backup of your computer.   There is never a guarantee that alternate drivers will work.

Note:   The setup may say no compatible hardware is found.  Manually install the drivers.
