Computer. Broadband dial up failed. Broadband dial up Internet authentication failed

The possible reasons are as follows:

First, the network signal is unstable. Sometimes this kind of situation is likely to occur when broadband operators upgrade and test the network, and it will be automatically restored after a while. If it can't be recovered for a long time, then you need to call customer service ** to report for repair.

Second, it may be that the modem is broken, and at this time, it will be unable to pull out the number successfully, and it will always be retried. Just buy a new modem and you're good to go.

Third, the network cable is broken, once the network cable is broken, of course, it cannot be dialed successfully, and a network cable can be prepared again.

Fourth, there is another possibility, that is, the broadband account and password are filled in incorrectly, which will also fail to dial, re-check, if you forget, you can go to the business hall to change the password.

Summary. Hello, the reasons for the failure of broadband dial-up Internet authentication are as follows: to determine whether the password you use is entered correctly, whether it is case-sensitive, and whether the suffix is added.

Determine if the unsuccessful dialing is due to arrears, and if you are unsure, you can call the respective carrier and ask. If it is not caused by the above two reasons, then determine whether you belong to the abnormal disconnection situation (including suddenly unplugging the router, so that the router suddenly loses power, or suddenly unplugging the router's WAN interface network cable, etc., at this time, from your point of view, the connection is disconnected, but the server does not stop your connection, so you cannot dial up successfully.

Hello, the reasons for the failure of broadband dial-up Internet authentication are as follows: to determine whether the password you use is entered correctly, whether it is case-sensitive, and whether the suffix is added quietly.
