Disconnect the network with adding attachments to the router email? 5

It is recommended that you test whether the type and size of attachments sent to the email have an effect. For example, attachments are divided into html txt jpg, and the size is divided into bytes, k, and m

See what kind of things will cause the network to be disconnected, or if all attachments will be disconnected.

I'm wondering if you have some security settings on your computer or network.

It may be a compatibility issue, you can try tp-link instead.

First of all, we want to eliminate the problem, first, try the same email with another mailbox, to send, if it will not be disconnected several times, it is the reason, if there is still a problem, try again** software or movie to try, if the same should be a problem with the router, replace it. Second, if the above problems can not be solved, try to reinstall the computer again, it should be able to solve, and then appear sure of the telecom operator's problem, I can say for sure, don't believe too much in the help of the 10000, those customer service are not professionals, they are just according to the training content to copy, in fact, it is not to solve the problem, in addition, you can report the fault, find a telecom professional to conduct a broadband rate test on your line, Take a look at how big your line can run to determine where the fault is.

If you get error 678 while connecting, then the network is in place.

The remote computer is unresponsive, which means that the data is sent out from the computer to the network card, including the transmission of ** line, and the data transmission problem in the process of processing the data from the port of the central terminal board to the return data to the computer will prompt 678 error, first confirm that the ADSL modem dialing is normal, because the IP automatically obtained by the network card is not cleared, so when dialing again, the network card cannot obtain a new IP address will prompt 678, the operation method is: turn off the ADSL modem, Enter the network connection in the control panel, right-click the local connection to select disable, after 5 seconds, right-click the local connection to select enable, and then turn on the adsl modem dial-up;

As long as the link light is not flashing, it means that there is no problem with the line signal, (sometimes the link light is always on, but the quality of the modem is poor and the performance is unstable) If the modem is good, then it is necessary to consider whether the modem and the network card are connected, and you will know it by ping. On the premise that all of the above is good: just start the computer again and you're good to go.

2. If the router is not set up correctly, you fill in the DNS address of the ISP in the router, select automatic connection, if the ISP is bonded to the MAC, you also have to set the MAC address clone in the router.

If you can't ping the router, it means that there is a problem with your router or the network cable connecting to the router.

First of all, you can go directly to the router to check whether the router network connection is normal

1. Whether the WAN port network has been connected and whether the DNS is normal;

2. Whether the local computer uses DHCP to obtain the IP, you can start - run, enter cmd, and enter ipconfig all in the pop-up black DOS window to check the DNS acquisition situation;

Users can try to manually enter the IP address and DNS, confirm the DNS error, and configure a manual DNS in the router.

The IP address set by the connected computer and the IP address assigned by the router conflict with each other, resulting in a disconnection.

It is recommended to change the IP address of the computer to be automatically obtained to avoid the situation that the IP address conflicts with each other and causes the connection to be dropped.

Dear users, hello:

First of all, take a look at the status of the indicator light on the router when the network is disconnected, if it is not normal, first troubleshoot the hardware problem. If you don't set it to automatically get the IP address, the manually set IP address will conflict (for example, with the router).

The router often goes down and the solution is as follows:

Cause 1: The network line is faulty.

Home Network Environment Cabling]:

1. There is a cat (modem): cat (modem) - router WAN port; The LAN port of the router --- a computer.

2. No modem: network cable --- router WAN port; The LAN port of the router --- a computer.

Cause 2: If the network cable is faulty, it is recommended to replace the finished network cable.

Cause 3: The router has an incorrect Internet setting and you need to reconfigure the router.

Solution: Reset the router and set dialing again.

Reset Router Method:

Method 1: There is a button [RESET] button on the back of the router, press and hold for 5 seconds, and the indicator light on the router panel will be off and then on, which means that the settings have been reset.

Set up router dialing:

The IP and DNS settings of the computer are automatically obtained.

1. Open the browser - enter the general router address is this or view the login information on the back of the router) Enter the route - enter the user name and password, (the default is generally admin).

2. In the [Setup Wizard], select [PPPoe Dialing] (some are ADSL Dialing), enter your Internet username and password according to the prompts, and save.

3. In [Network Parameters] --WAN Settings], select [Normal Mode], and select [PPPoe Dialing] in the three options of [Connection]. The next step is to select [Auto Connect], Save, and Exit.

4. If you want to use wireless wifi, your router must have a wireless routing function, in the settings, turn on the wireless routing function, here, the wireless signal signal is changed to one of them. The strongest anti-interference. You can also set a password for your Wi-Fi connection.

Reason 4: Router hardware is damaged.

Workaround: Replace the router with a new one.

I can tell you unequivocally that there is a problem with the router settings. In addition, you can guess that the IP of your computer's network card is automatically obtained. Solution: Choose one of the following two or both:

The place where you can access the Internet restricts you from using the router, you can enter the route management interface to find a single computer that can access the Internet and connect to the router, be careful not to connect the cat first. Then clone the MAC address of your computer into your router and you're good to go.

If the above problem is not present, it is a problem with the router itself.

You reset the router and then reset the router and try again, if it still can't be solved, try a different router!

I guess it's a router problem.

Router port.

Firewalls or something.

Is it that your router has changed the management settings after letting others rub the network, and now the router has a variety of control functions. You reset it (factory reset) and then go to the setup wizard settings, and you should have no problem.

Are you connected wirelessly? If so, change the password for the network connection to the same as for the router.
