The laptop cannot be connected, error 815

Error 815" is a broadband connection error message for the computer's operating system Windows Vista, which is equivalent to error 678 on the Windows XP system, which is the remote computer not responding.

Fault causes: ADSL modem problems, NIC faults, firewall or antivirus software configuration errors, network protocol errors caused by abnormal shutdowns, ADSL ISP server failures, etc.

Solution: 1. Check whether ** is normal. If it is normal, turn off the computer for 10 minutes and then turn it on.

2. Check whether adslmodem is normal. Restart the modem, if the external link indicator of the modem keeps flashing, check whether the devices are connected correctly, whether there is an error in connecting the ** extension, and whether there is a problem with the splitter.

3. Restore all connection defaults.

4. Reinstall the operating system Windows Vista.

Hello, I searched on the Internet, you see.

It is recommended to instruct the user to check the user terminal:

Instruct the user to check the user side:

modem normal state: the power light is always on, the synchronization light is always on, and the NIC light is always on.

Power Lamp :p ower

Common sync lights: DSL, ADSL, LINK,

Common NIC lights: PC, LAN, and Ethernet

The interface on the splitter: LINE to the incoming line, ADSL or M to the modem, phone to the **machine.

The first step is to check whether there is a centralized fault in the area where the user reports the fault (ask the user's broadband account first).

The second step is to ask the ADSL broadband user if the modem has been restarted, and if it has not been restarted, please restart the modem (turn off the power of the cat and turn it on again), and then let the user reconnect to the network again after the three lights of the cat are always on.

The third step, after restarting the cat still can not be recovered, first ask the user the status of the cat's light, the synchronization light is still not on or flashing should be recorded to send the order to the city for processing. If the NIC light is not on, please plug in the network cable (both ends) and send a ticket if it is still not connected.

Optical fiber + LAN users directly let users check whether the network cable is plugged in. If you are unable to resume accepting orders.

You should be using the wireless routing modem, I have used it before, sometimes this situation occurs, at that time I disabled the local connection, just enable it, it is estimated that you also disabled the local network card, try to enable it.

Look at the light of the network card is not on,Determine the quality of the network card,Next**up,Unplug **Determine the problem of the line,If the cat's light is determined to be good,It may be a system problem,My win7 system is difficult to pull up with a cat,Just use the route,It's a problem with the system itself。

It's not that the PC light doesn't light up, I'm pretty sure it's your network card is broken.

Reasons for this: The 813 error is generally caused by the creation of multiple dialing software.

Solution:1Remove all broadband connections;

2.If the method in the first step cannot solve the problem, please open the Control Panel --- Device Manager, and right-click the option under the network adapter to disable;

3.After restarting, right-click the option under Network Adapter to enable it;

4.Just set up a new broadband connection.

Error 815

It is not possible to establish a broadband connection on the computer.

815 errors are rare, mainly line or server problems, if these two are okay, then you can re-create a broadband connection, this will not, first you have to remember your account and password, and then the online neighbor goes in, deletes the current one, and creates a new connection on the right.

However, it is very likely that the network cable was interrupted, or the cat was broken

Broadband Internet access prompts error **815, the common cause of the fault is the line, network equipment failure and improper setting, a small number of which is caused by the conflict of network cards and other equipment. If fiber broadband is used, you can troubleshoot the problem by following the following steps:

Step 1: Observe the running status of the optical modem, under normal conditions, the power indicator P0Wer, PON, and LAN are always on, if all of them are not on, it means that there is no plugged in the power supply or the equipment is faulty, if the PON light is not on, it means that the optical fiber is not connected well or there is no signal, and the LAN light is not lit, which means that it is not connected to the computer.

Step 2: If the line connection is normal, turn off the modem, restart it after 5 minutes (check whether other connected devices are used, such as routers, disconnect related devices, and directly connect to the computer to dial), and restart the computer to try again.

Step 3: After startup, check whether the computer NIC indicator and modem status are normal.

Step 4: If the indicator is normal and both the modem and the computer are invalid when you restart, it is recommended to re-establish the broadband connection and then dial up.

Is it a vista system, the remote server is not responding.

See if this helps you (you may need to sign up) to fix the problem with error 815. Vista ADSL Internet access, limited local connection? Network not recognized? Come and solve it perfectly with me!

The reason why the router cannot connect to the network.

Restart your router and see.
