Internet speed suddenly becomes very slow, and web pages can't be opened.

How about trying to increase the internet speed

Magic Optimizer , the internet speed will be increased to your highest point.

Principle: If the MTU of the local machine is larger than that of the gateway, large packets will be split and transmitted, which will generate a lot of packet fragments, increase the packet loss rate, and reduce network speed. Setting the local MTU to be smaller than or the same as the gateway's MTU will reduce packet loss. The transmission unit buffer is filled in: 262080. there is no effect on the system. it is a matter of validity or invalidity.

Optimize the computer's receive buffer and change the network's maximum transmission unit (MTU) by setting. More plainly understood is the maximum packets (in bytes) accepted for transmission over the network.

The steps are as follows:

I. Reservable bandwidth change: (release the reserved 20% bandwidth)

Remember to type gpedit.msc in Run to go to Admin touch screen-Network-QOS-Limit Reservable Bandwidth Change the value from 20 to 0.

Two.

1. Open Optimizer and select System Optimization

2. Select Network System Optimization in Optimizer

3. Fill in Maximum Transmission Unit Size: 1492, Maximum Data Segment Length: 1452, and Transmission Unit Buffer: 262080

E.g. PPPoE (ADSL) is optimal as follows: 1492. EtherNet: 1500, Dial-up (modem): 576

4, click Optimize

5, restart the machine

The real meaning of the increase in network speed! (Experience sharing, the effect is obvious) used a lot of other netizen's method, compared to see only this method can really speed up the web page open speed! Especially when you open a web page with a lot of pictures, the speed of the web page before and after using this method is completely different! But to make it clear: only the beginning of the speed much faster, a few minutes later, the speed will drop, in fact, this is enough! Just like you get on a crowded bus, if you stand in a good position, you will be very easy to get on the bus, while others will be difficult, or even on the bus! If you have a slow Internet connection, you may have encountered some web pages that don't even show the add-on codes, but if you use this method, you'll see immediate results!

Try it, you'll be pleasantly surprised! The method is as follows: (If you do not believe that you can first backup registry, my personal experience many times, I do not think this is necessary!)

1, run "regedit" to open the "Registry Manager"; then, according to the following path to find HKEY_LOCAL_MACHINE＼SYSTEM＼CurrentControlSet CurrentControlSet＼Services＼Tcpip＼Parameters.

2. Right-click on the space to the right of the "Parameters" subkey and select "New". "→"DWORD值", name it "DefaultTTL", then, right-click the mouse and select "Modify", and modify its value to "DefaultTTL" in the pop-up window. In the pop-up window, modify the value to "80" (hexadecimal) or 128 (decimal).

3, and then in turn, the following new "DWORD value", and modify its value (if there are two values, the former hexadecimal, the latter decimal): "EnablePMTUBHDetect"="0"

"EnablePMTUDiscovery"="1"" GlobalMaxTcpWindowSize"="7FFF" or "32767" (I am modifying it to 372300, same setting later)

"TcpMaxDupAcks"="2"

"SackOpts"="1 "

"Tcp1323Opts"="1"

"TcpWindowSize " = "7FFF" or "32767" (93440 or 186880 or 372300, depending on the network)

Ways to increase Internet speed

Go to execute hit regedit to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

New DWORD

Named GlobalMaxTcpWindowSize Value changed to 360000 Select Decimal

New DWORD

Name TcpWindowSize Value changed to 360000 Select Decimal

New DWORD

Name Tcp1323Opts Value changed to 1 Select Decimal <

New DWORD

Name DefaultTTL Value changed to 64 Selected Decimal

New DWORD

Name EnablePMTUDiscovery Value changed to 1 Selected Decimal

New DWORD

Name EnablePMTUBHDetect Value changed to 0 Select Decimal

New DWORD

Named SackOpts Value changed to 1 Select Decimal

New DWORD

Named TcpMaxDupAcks Value changed to 2 Select Decimal

After that go to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\

interface (this interface should be added by yourself) point to the interface to add a new code. (name interface)

New DWORD

Name MTU Value changed to 8000 (if use 10M)

1500 (if use 1.5M)

2000 (if use 3M) Select decimal

After that, go to the DEFAULT section of the HKEY_USERS\\DEFAULT\Software\DEFAULT\Software\DEFAULT\Software. DEFAULT\Software\Microsoft\Windows\CurrentVersion\InternetSettings

New DWORD

Name MaxConnectionsPerServer Value changed to 00000100 Select decimal

New DWORD

Name MaxConnectionsPer1_0Server Value changed to 00000100 Select Decimal

After that, we go to
