I help with a friend of a router or the switch

I'm also a 4-household ADSL. I often have a headache when someone gets something to watch a movie.

I've also worked on a lot of software. But now with a firewall, it's basically useless.

I don't believe there will be any software like this that can solve the root cause in the future.

So the best thing to do is to use a hardware upgrade to allocate the speed of each port.

He may also use the software to limit your speed, and if the limit is not very large, you will not be very stuck. Estimated to be the reason above.

Estimate he's a**something,Because the general router can't allocate traffic unless it's to limit you with software,According to what you said, I guess he's in**Movies and the like,The network bandwidth is occupied.,If you use software, it's a bit despicable.,It's recommended not to share it with others.,I used to too.,Someone else is under something, my game is not good.,Finally, I play 1 line by myself!

No, there is a virus on his computer that is taking up bandwidth. It's also possible that P2P is installed that limits your internet speed.

You can use ARP firewall, Kingsoft has a good one.

Routers can also be set up.

Throttle your internet speed.

You need to use the router connected under the switch as a switch with wireless function, how to set it:

1. Windows key + R, pop up the running interface, enter cmd enter.

<>3. Open the browser, enter the gateway address, and log in.

4. Enter the main interface, because modifying the LAN port IP may be restarted, so here first turn off the DHCP service of the router, of course, if you don't feel troublesome to restart, you don't need to do this step, as shown in the figure, click "DHCP server" "DHCP server settings" "Do not enable" "Save".

<>6. After the DHCP service is closed and the IP address is modified, it means that the computer cannot automatically obtain the IP address when connected to the router, and a fixed IP address must be set to log in to the router. In addition, if the LAN port of the computer is set, the IP address of the computer must be set to this range before you can log in to the router.

7. Using the router as a switch will not affect the wireless function of the router and can still be used normally.

The switch and router can be used together, and the switch can be connected to multiple routers, and the two methods can be set up (multiple routers are set like this):

The first method: dynamic IP mode.

1. Plug in the router, don't connect the switch first, reset the router (restore the factory);

2. Connect the computer to any LAN port of the router and enter the setting page;

3. Set according to the dynamic IP;

4. Then set the SSID, encryption method and password;

5. Save and restart;

6. After setting, connect the network cable from the switch to the WAN port of the router.

The second method: wireless AP mode.

1. Connect the computer to the LAN port of the router and change the IP address of the router. For example, most router addresses are, we just need to change the router IP address;

2. Turn off the DHCP function of the router in the settings;

3. Finally, connect the network cable from the switch to the LAN port of the router (any one is fine), note that it cannot be the WAN port.

You can use a network cable to connect the WAN port of the router, and the LAN port of the router can be connected to any interface of the switch.

However, using the router for the first time requires a bit of setup

Plug the network cable into the WAN port of the router first, and then connect the LAN port of the router to the computer.

Then enter the account name and password (there is also a hint of raw data on the back of the router) OK.

After entering the settings interface, follow the setup wizard and you can surf the Internet normally.

If it is abnormal, you may wish to click the reset button of the router and set the router again.

If you don't need to connect to the Internet, you don't need to connect to a router, set a fixed IP address for multiple computers (the first three digits of the IP address must be the same), and the same workgroup can form the same LAN.
