Can t get online, don t know what the reason is

First of all, let's explain a problem, not a few megabytes of bandwidth can be used on a few computers.

There are 2 situations for this question you are talking about:

1. Telecom limits the number of MAC addresses for your broadband access, and you can only go out of your port with 2 MAC addresses, so you can't go on when they can, that is to say, you can only have 2 computers at the same time.

2. China Telecom has limited the number of your broadband accounts online at the same time. The premise is that you are using the PPOE mode (that is, the ordinary ADSL mode or the fiber-to-the-cell mode, which requires dial-up. It's not the kind of way that you can access the Internet as soon as you turn on the computer and just plug in the Internet cable).

I don't know if you are using a dial-up number, if it is a dial-up number, whether the 3 of you have an account or 3 accounts. According to what you said, I guess there should be only 1 account, which means that this account is restricted to 2 people at the same time. If so, you can ask Telecom to open it for you to go online for 3 at the same time, but it is estimated that Telecom will overcharge.

In addition: If the network is not connected, QQ cannot be logged in, and it generally indicates that there is a problem with DNS.

There is no such thing.

Your wiring plug is not good, and it is falsely connected.

The activity is good.

Your modem has a lot of plugs. Ha ha.

If you are not restricted, Telecom will not limit you because you have two or three machines, and no number of users will check them one by one.

If it's a DNS problem. I think it's because of your routing issues. You can reboot your router appropriately, or you can use a fixed IP address instead.

Set a fixed IP address for each other in the LAN.

Then, make a note of the DNS address of the telecom you use. are all filled in fixed.

The problem should be solved.

This should be something wrong with your settings.

If you look at other people's DNS and gateway settings, it's a telecom problem if you can't get on it if you set it to the same.

The telecommunications bureau is limited, I used to share 1m broadband with my neighbors, and then I couldn't get on the Internet (both people couldn't get on), and I could go to the telecommunications bureau to ask the reason for a while. Later, the computer repairer was called to take a look, but they said that there was no problem with the hardware, and it was the telecommunications bureau that limited it. Later, when my family reported the Internet, I asked the waiter, and they said this:

If you are a few m broadband, you can only have m computers to access the Internet at the same time.
