Select "Start Programs Management Tool DHCP".

Right-click Scope Options and select Configuration Options from the shortcut menu, and the Scope Options dialog box appears. Among them, "003 router" and "006dns server" are set to check, and fill in the gateway IP address in your hotel.

Someone in your LAN is connecting to the router without permission, causing the route finding error in the network.

It should be a network problem, the IP and gateway settings are wrong, and they are no longer together, so there will be similar exceptions, 1Uninstall the client first, then open the Network and Sharing Center -->Local Connections--> properties, and find if there is a virtual adsl device in "This connection uses the following items", and if so, uninstall it.

3.Then enter "netsh int ip reset", and then press enter, prompting to restart the worldbump, and then restart the computer.

4.It is recommended that you check whether the IP address is wrong, and if not, you can update the driver.

6.Delete the network card driver from Sotudan, and then update the driver, let the system recognize the network card as another network card, and then create a dial-up link.

The phone I use.

Android or Apple.

Android. As a result, I can't even go online.

I can't log back to that ** anymore.

<> enter or see if you can enter.

Change static to automatic.

Summary. Don't plug in the router for the time being, and then connect the router to the computer and enter the settings page

1. The IP address of the router is adjusted to [LAN port settings].

2. In [WAN Port Settings], select the static IP, fill in the parameters according to your question, and change the mask to.

3. Clone your computer's Mac to the router.

After saving and restarting, plug the broadband network cable into the WAN port and see if you can access the Internet. (You'll need to use your own router later).

Setting the IP address and default gateway is always not set.

Routers only have password recognition autodialing, but you can also set up automatic logins, but the security is not very good. 1. If it is a telecom, it means that your network is not connected, check the network, find a network administrator, and check your account and password or the number to be dialed, uppercase. 2. Check your computer system, right-click on my computer, left-click on properties, then click on hardware, click on Device Manager, and see if there is a yellow question mark, whether there is a problem with the network card.

As long as the gateway is not modified, it is the default, it may be that there is a problem with your system or it conflicts with anti-virus software, I am a network technician, and I am looking for me if I can't do it.

IP and gateway are all the same, set it to 0 and try!

1. It may be that the router and the telecom are not assigned to this IP in the same network, so try it instead.

2. The subnet mask (DNS) is default.

3. If you use PPPoe to surf the Internet (that is, you need a username and password), install the Internet in the router and fill in the username and password.

4. Disable the local connection, and then enable the wireless connection.

5. The default gateway means that if a host cannot find an available gateway, it will send the packets to the default specified gateway, and the gateway will process the packets. The gateway used by the host is generally the default gateway. A computer's default gateway cannot be specified casually, it must be specified correctly, otherwise a computer will send packets to a computer that is not a gateway and will not be able to communicate with computers on other networks.

There are two ways to set the default gateway: manual setting and automatic setting.

The IP address of the PC you are talking about is the IP address of the Internet.

You'll need to tick the address of your local connection to and try again

Some route resets can only be done by pressing reset and then powering on!

Your router is not on the same network as the IP assigned to you by Telcom. Changed to the default subnet mask (DNS).

If you are using PPPoe to surf the Internet (that is, you are given a username and password), install the Internet inside the router and fill in the username and password.

Then disable the local connection, and then enable the wireless connection.
