D link Router Problem I have 2 computers at home and find that the network speed is slow.

The cable separated by the cat is connected to the WAN port of the router and the LAN port of the computer, and the MAC address cloning function is enabled after setting the user name and password for automatic dialing.

If you still can't connect, you can try to upgrade the router firmware.

Reset the IP, all changed to auto-get!! Try it.

Incoming page rows? If you can't get in, it's possible that the route is broken.

See if the crystal head is broken???

First of all, look at whether there is a difference between the connection method of your desktop and notebook, for example, the desktop is connected to the router through wire, and the laptop is wireless, so if the wireless is stable, you can consider replacing the network cable for the desktop.

If desktops and laptops are connected to the Internet with wireless network cards, then you can consider the vitality of the wireless network card drive, adjust the router antenna angle, and then whether there are household appliances around the wireless environment that use the same frequency band, such as cordless ** and microwave ovens, etc., because the wireless use of this frequency band will cause co-channel interference; You can try to modify the channel, according to past practical experience, if similar wireless networks use the same channel, it will cause signal interference.

In addition, the transmission distance of 100m refers to the indoor transmission distance in the theoretical state, but in fact, the wireless is very disturbed by the surrounding environmental factors. In the general home or office environment, there are walls or columns passing through, and the wireless signal attenuation will be more.

Only with high power is OK, and wireless routing with 2 antennas is generally fine.

There are many reasons, and the system, software, and network card are all useful, and they have to be eliminated one by one.

The location of the wireless router is changed first. Are there any interferences?

Can be connected means that the computer is connected to the router, but the route is not connected to the external network.

In general, there are two ways to do this.

1 If the line fails, dial up the Internet directly with the computer and skip the route. If the connection is normal, it should be a routing problem, and the connection is still not normal It may be a line problem, and you can directly call ** to customer service to check the problem and warranty.

2 Hardware issues. If it is a hardware problem after the interview, you can consider whether there are too many connected devices that cause the routing data to be blocked, and see if there is a heat source around the route, which causes the routing working temperature to be too high and causes feigned death.

ps: Is the route set too much, such as speed limiting, working mode and so on, many routes with speed limiting function, but the speed limit of home routes is actually a kind of soft speed limiting, through the routing console software speed limiting, if set will increase the load of the route, it is easy to cause routing problems.

Personally, I think the second case is relatively high.

Network failure, I have had this situation, you call ** to the customer service center to refresh the port for you, restart the wireless router every three or four minutes, it's OK...

If there is a fault in the line or the external network, you can contact the network operator.

This depends on what is written on the exclamation mark, which may be restricted. It may also be an IP conflict, if the IP is used, you can go to the local connection of the wireless to modify the IP, and if it is restricted, you have to go to the gateway to set it,,。

Factory reset the route to try it.

1. If the router itself has a power-saving mode to select, remove it.

2. Remove the power-saving mode of the router in the computer.

This way, your computer will always be connected as long as the router has a network signal. Therefore, as long as several commonly used networks are unconnected, you can judge that the external network signal is gone. Just find extranet customer service.
