win7?
For the concept of bandwidth, a metaphor for comparing images is highway. The amount of data that can be transmitted on the line per unit time is commonly used in bps (bit per second).
So, how to modify its value?
1, point"start”——point"run"——enter>Gpedit.msc” (note that there is no input when it is entered; ”, lose Gpedit.msc), then click "OK" (or enter), it will open the system "group policy", "
2, we began to adjust "group policy": In the left column of Group Policy, open “Computer Configuration"——“Administrative Templates”——“Network”——“Qos Packet Scheduler”. At this time, there will be a “restricted bandwidth reserved” on the right side. Double click on the “Right to retain bandwidth” in the right window, and select “In the Restricted Bandwidth Properties” window in the “Restricted Retained Bandwidth Properties” window. Enable ”, then set the value in “Bandwidth Limit" to “0”, click “OK" This will be fine
The second method is more dangerous to change the registry to unfamiliar The player in the registry should not try it. If it is wrong, it is dangerous!!
Run “regedit” to open the "Registry Manager"; then, find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters by the following path.

& ldquo; DWORD value & rdquo ;, and change its value (if the value of two, the former is hexadecimal, which is decimal):
& ldquo; EnablePMTUBHDetect & rdquo; = & ldquo; 0 & rdquo;
& ldquo; EnablePMTUDiscovery & rdquo; = & ldquo; 1 & rdquo;
& ldquo; GlobalMaxTcpWindowSize & rdquo; = & ldquo; 7FFF & rdquo; or & ldquo; 32767 & rdquo;
& ldquo; TcpMaxDupAcks & rdquo; = & ldquo; 2 & rdquo;
& ldquo; SackOpts & rdquo; = & ldquo ; 1 & rdquo;
& ldquo; Tcp1323Opts & rdquo; = & ldquo; 1 & rdquo;
& ldquo; TcpWindowSize & rdquo; = & ldquo; 7FFF & rdquo; or & ldquo; 32767 & rdquo; (93440, or 186,880, or 372,300, depending on network conditions)
