Xiaobian computer recently appeared broadband connection error 691 (due to the invalid username or password on the domain and refused to access), I checked the Internet and found that this problem is still relatively common, the following small series Let me introduce how to solve the broadband connection error 691. (1) User name and password are incorrectly filled in. (2) If the user account password is filled in correctly, proceed to the next step to continue processing; it is recommended to rebuild the dial-up software (if you do not know the dial-up software, you can refer to the account): If you reinstall the dial-up software Normal, the reason is "Delete software lost"; If the fault persists after reinstalling the dial-up software, please call customer service 10000 Telecom (10060 Netcom/10050 Railcom) to report the obstacle. Broadband connection error 691:1: An error occurred on the domain name (user name or password was entered incorrectly). 2: The server does not reflect, (the computer user port is wrong, or the account is not activated). 3: The telephone or broadband due arrears. The reason for the error: 1. Telecom limits the number of accounts you use. For example, you can use 4 accounts for 4 people. Now 4 people are using it. Your dialing is error 6912. You are not disconnected after using it, at least the server is still there. Did not disconnect, I thought you are still using, and the above situation is similar, so the error 691 suggests: every time you turn off the right button on the broadband connection, click the disconnect error 691, do not always stalk the dial, wait a few minutes Try again, if this happens all the time, call customer service 10000 Telecom (10060 Netcom /10050 Railcom), tell the staff that your computer error 691 can not go up, then she asks "How much is your broadband number", tell She has your account, and then she sometimes asks who you are opening an account, who is answering the account, and then after a few minutes she will find someone to help you with the broadband connection error 691 solution: there is a wireless router in the factory office And the home installed a new broadband, have not bought a router, so only share an ADSL account with the brother to access the Internet, a network cable between the two portable plug and unplug. But what is depressing is that you can connect to the network when you plug it in your brother's hand, but when you plug it into my hand, it always prompts error 691: Username/password is wrong. But what is certain is that I have never entered the wrong username or password, so I have not set the dialer and the machine for a long time! ! ! Depressed... I asked 10000 to ask, Miss Telecom insisted that I made a mistake, not their problem. Later, I searched the Internet for some related articles and finally solved the problem —— the original telecom bundled my ADSL account with my brother's mentioning network card. 1. Run on the mobile phone of Big Brother (in the “Run” dialog box, enter “ cmd" can call up the command line) and enter the ipconfig/all command to view the network configuration information, find the PhysicalAddress in the local connection, and record it. 2, then enter my notebook, enter the device manager, find the network card in the network adapter, right click on the network card name to select the property, enter the "advanced" tab, select the NetwotkAddress item in the left box , select the value of the right side of the value, fill in the MAC address just recorded (not case sensitive, do not add “-” symbol). Maybe everyone will come across in the future, just study! ! ! This article comes from [System Home] www.xp85.com
