The router is set up. A notebook can access the Internet. Computers can t do it. Error 815 What s go

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!

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.

Don't worry, in the connection settings, you need to set the IP first to connect locallyAccording to the maintenance staff, if it is not set, the Vista system will not even recognize the cat, so there will be an unrecognized network with a yellow exclamation mark on the connection in the lower right corner. At this time, the dialing will prompt error 815.

Workaround: Network and Sharing Center --- manage network connections --- local connection --- properties --- IPv4 --- properties, open and select"Use the IP address below", basically in line with the cat's IP for the last this float at 2 10).

DNS that don't fill in the dot to confirm it should be OK as long as the network cable is okay This can be solved. It didn't take 10 minutes for the maintenance man to come over and solve the problem. Hope it helps.

And if it doesn't work, it means that there may be a little bit of a problem with the network cable, because sometimes the network cable connection that can be used in the XP system may not be available in the V system, and you need to consult your broadband operator, their broadband system support does not support the V system.

I hope it will help you, if you are troublesome, it is also good to change to XP SP3.

Error **815

This is the error message after connection failure in Vista, which is similar to error 678 in XP. None of them can be linked to the server.

Solution: First, make sure that the modem signal status is normal and the user NIC status is normal. Then use the PPPoE protocol that comes with the system to establish a link, @cnc with the specified user name, no need to enter a password, and log in to the test.

1) If the login is successful, but the client can not be connected, then judge that there should be no problem with the network, generally it should be an operating system problem or a system version problem, it is recommended that the user reinstall the system and try it.

2) If you still can't log in @cnc, it may be a network problem (generally a broadband port failure or a device network failure), and a few are user operating system problems, which must be defined by a notebook test.

Network issues! I often have the same problem! Just get the cat up again!
