Solving Vista can't connect to network problems

Vista system can adjust its network settings to make the most of available network bandwidth. However, in some cases, Vista will fail to connect to the network, usually because some older routers are not always strictly following standards. On the Microsoft website, there is a good white paper "Windows Vista TCP/IP Networking and IPv6 Migration", which explains in detail how Vista adjusts its performance, explains the basic principles behind the default settings, and the impact and implications of the changes. You can download it and read it.

If you find yourself unable to access a network, you can log in as a superuser, enter the command line mode, and use the method described in this article.

There is a little trick here: an easy way to run the command line tool is to create a shortcut to “cmd.exe” and right click on this shortcut (of course you must be superuser) Log in), select “Run as administrator from the pop-up menu.

To view the current TCP optimization settings, type the following command at the command line:

C:\\Windows\\system32>netsh interface tcp show global

You should Received an output similar to the following:

(Query Activity Status …) Querying active state……

(TCP Global Parameters) TCP Global Parameters

----------------------------------------------
< Receive-Side Scaling State : enabled

Chimney Offload State : enabled

Receive Window Auto-Tuning Level : normal

Add-On Congestion Control Provider : none

ECN Capability : disabled

RFC 1323 Timestamps : disabled

To disable these settings, execute the following command from the command line:

C:\\Windows\\ System32>netsh interface tcp set global rss=disabled

autotuninglevel=disabled

If the input is correct, you will receive: Ok.

Ok, now try connecting again Look at the network. However, if you are using a wired network, you may need to "fix" your network connection or plug in the network cable; for wireless networks, just disconnect the network and then connect to the network.

To set the network stack back to its normal state, just type the following command at the command line:

C:\\Windows\\system32>netsh interface tcp set global rss=enabled

autotuninglevel=normal

Note: The autotuninglevel here is set to “normal” instead of <;enabled”.

I hope this little trick will help you solve the problem.
