The campus network is extremely slow, ask for a solution

1. All-round detection computer

If you use your computer for a long time, you may have too many unwanted programs, Trojan viruses, or corrupted network cards. These issues may cause your internet speed to slow down. You need to use antivirus software to check the overall situation, check them one by one, and finally restart the computer to check whether the network speed is normal.

In addition, the piracy system itself has many system vulnerabilities, which may also affect normal use.

2. Turn off the firewall

The firewall is the guarantee of the entire AMB network, so this method is not recommended for everyone, but you can test whether the firewall causes network speed problems.

Click on the Start menu, find Control Panel - Windows Firewall, click on the left side to enable or disable the firewall, and turn it off. Don't forget to open it again after the test.

3. The bandwidth limit of the Baxter network of the computer itself.

By default, the computer limits the system bandwidth to 20%. If this setting is not configured or disabled, the computer will use the default value of 20%. Click on Winr, enter, and then find Computer Configuration - Management Templates - Network - QoS Packet Scheduler - Limit Reserved Bandwidth.

We enable this configuration and change the bandwidth limit to 0 so that we can use 100% of the bandwidth.

4. Reset the network

Press the Win X key combination, select Command Prompt (Admin) or Windows PowerShell (Admin) mode, type [Netsh Winsock Reset] and enter, you will be prompted to reset the Winsock directory successfully. Restart your computer and try again to see if there is any improvement.

5. Change DNS

Usually when we visit **, we usually access the domain name, and the computer needs to convert the domain name into an IP address to access normally, which is also the main function of DNS. Due to the widespread use of CDNs, different IP addresses can be resolved when different DNS are used, which affects the resolution speed.

1. Reasonable and economical use of the net

Use on-campus resources as much as possible for large traffic uses such as live TV broadcasts and **learning, and choose IPv6 as much as possible for large files (log out of the gateway account first). As much as possible, it should be used for essential purposes such as studying, and less for non-essential purposes such as games.

2. Avoid the peak hours of the dormitory

It is not excluded that there will be short-term peak congestion, at this time, suspend the use of the Internet, digest and absorb the information that has been used, or go to the teaching area to surf the Internet, avoid crowding more and more slowly, and improve the efficiency of Internet access.

3. The dormitory area uses wired network

The dormitory's white panels are directly connected to the campus network and can use IPv6 network and on-campus multicast TV (Oriental Channel). Before the wireless renovation of the Nanyuan dormitory, try to use NJAU-WLAN wireless Internet access as much as possible, or use NJAU wireless signal in the teaching area.

4. Log out of the gateway login in time

Regardless of timing or traffic metering, try to actively log out of the gateway login. If it is troublesome to log in and log out repeatedly, it is recommended to change the traffic mode, and there will be no traffic loss if you do not use it.

Reason:

1. Surf the Internet through a router sharing account, and multiple people sharing an account will cause slow Internet access.

To solve this phenomenon, you only need to change the upper connection of the router from its WLAN port to the network port (LAN port) of another computer. Second, small routers or switches used for tapping are prone to aging resulting in degraded or unstable performance, which is also a common cause of slow network speeds and needs to be updated in a timely manner.

2. The demand for Internet bandwidth is growing.

As a unit user, the school has a high bandwidth rental fee, and the bandwidth utilization should be considered. The school's funds are relatively tight and need to be arranged as a whole, and it also takes a long period from application to implementation, so it can only increase the export bandwidth in a stepwise way.

3. Some foreign ** visits are slow.

This is a common phenomenon in China due to factors such as sharing international exports and international management. To this end, the school applied for the 50m international boutique line of telecommunications at the beginning of this year, which solved the problem of slow Internet access in some foreign countries, but some of them still could not solve the problem of slow access under domestic conditions.
