There are many aspects for system optimization, and the improvement of Internet speed is one of a kind of optimization, which is also the more important reasons for optimization, we introduce several acceleration methods in the following:
<b> </b>
1. Modify the registry
Note: Please back up your registry files before changes.
a, start the Registry Editor and complete the following settings. HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ Class \ NetTrans \ 0000, key name: MaxMT, change the value to 1500.MaxMTU is the largest TCP / IP transmission unit, in the standard TCP / IP protocol, the data to be transferred is divided into smaller groups for transmission, and the size of each group is 576 bytes. Default bytes in Windows are 1500 bytes, which is <span>the Ethernet packet standards. Many broadband users set the value to 576 to optimize the system while originally surfing the internet through dial-up, and now we have to change it back to the default values. Although in theory the value of PPPoE in ADSL we use is smaller than this value, but in general we are satisfied with this value. This is the most critical part of ADSL optimization for many users.
</span>
<span>b, In the HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ VxD \ MSTCP, modify the following string value.
DefaultRcvWindow = 32768
DefaultTTL = 64
Where defaultRcvWindo transmission unit is the size of the buffer. It will result in packet blocking to reduce transmission efficiency if the Buffer is too small. If the buffer is too large and a packet is error, it will cause all the partitions in the buffer discarded and resent, and also reduce efficiency. The size of the value is related to the speed of the Modem, preferably 32768. Default TTL is the TCP / IP packet's life, if the transmittion time of the packet in the Internet is longer than the life of the packet, the packet will be discarded. Change Default TTL to be larger is useful to transmit the information to be further. Some friends may feel too much trouble about above optimization, perhaps there is still some doubt about the final result. We can use Advanced SystemCare PRO 3 to modify the registry and improve system performance. </span>
2. Change the operating system to Windows XP
After changing to Windows XP, Many friends found markedly improved Internet speed and the stability of the network has improved a lot, stop and Shock basically do not exist. So it is a better way to solve the problem by changing to Windows XP.
3, let start more quickly
After installed ADSL, each time the starting speed of your system slows down significantly, it will take up to 2 to 3 minutes sometimes. Actually, ADSL don't affect PC, but rather the network card, the reason is very simple: the installation of network card is installed in the network card TCP / IP protocol and not set TCP / IP, the system defaults to "obtain IP automatically address ", so every time it will constantly searches the network DHCP server to obtain their dynamic IP addresses when you start the system, the computer will search repeatedly if the DHCP server don't be searched, so the starting speed will be significantly slower.
Solution: set a fixed IP address for the system.
a, open the "Control Panel” → “Network” , select TCP / IP protocol of your network card in the" Configuration ", and then click " attribute. "
b, select "IP address→ IP address of the specified input,IP address and subnet mask, at last, click " OK. "
c, restart the computer, the speed is faster.
But for some extern7al ADSL Modem, you can't surf the internet if it don't set to “obtain IP address automatically How to do it? Above the versions of Windows Me, it has been optimization for the search time, it doesn't matter whether you set or not.
In addition, you also can find junk files and remove junk files to improve the speed of surf internet.
