2 laptops are connected to wifi and the second computer cannot access the Internet high score bount

"Allow Internet connection sharing" is also checked for the 3G network card of the first computer, and the Internet connection sharing of the wireless network card of the first computer itself. This option is available in the Wireless Connection Properties of the network card.

On the computer where you plugged in the 3G network card to access the Internet, click Control Panel, Network Connection, Right-click 3G Network Card Connection, Properties, Advanced, and check "Allow other network users to use this computer's Internet connection"; Then select your 3G network card connection in the drop-down box below - > OK.

Then, on your other computer, the same as above, and you're good to go.

Have you set up sharing?

Reconfigure the router settings.

Maybe it's a problem with the router.,My roommate in the dormitory has also encountered this kind of problem.,At first, you can connect with Tengda.,Later, you can't connect with the fast one.。 It really doesn't work, you can even connect the router to your girlfriend's laptop.

1 First check whether the wireless network card that cannot be connected can work normally (whether the driver hardware switch is turned on) 2 Check whether the routing settings restrict the MAC address of the network card.

That's only found a wireless router, but not connected to the Internet, enter the corresponding ** according to the brand of your router, and set up the login again.

This kind of thing of several routers in series,Sometimes it needs to be configured and connected.,It's not just plugged in and used because it's not just a switch.。。。 If it's a switch, it's okay to wiring it any way. I'm here to tell you the easiest way to do it:

First of all, you need to learn to look at the names of each network interface of the router, which are generally marked on the top of the port, such as lan and wan.

The WAN port of your original wired router is still connected to the incoming line of the network cable, the LAN port is connected to the WAN port of the wireless router, and the remaining LAN ports can be connected to the wired computer.

Under normal circumstances, there is a problem with your Internet access, but some routers of different brands cannot obtain IP after being connected in this way, because of some incompatibility problems on the DHCP protocol. If there is an incompatibility problem, then follow the following methods to get it, you need to know a certain router configuration knowledge:

After setting the name and password of the wireless network, confirm that the mobile phone can be connected to the wireless network, connect the LAN port of the wired router to the LAN port of the wireless router, and turn off the DHCP function of the wireless router (mainly to prevent DHCP conflicts).

The network cable of the computer host is connected to either LAN port of the two routers.

Be careful not to connect the network cable of the computer to the WAN port, so that you will not be able to access the network.

The wireless router is kept in factory settings, and a cable is connected from the original router to the WAN port of the wireless router.

What do you do with two routers for two computers? You can simply scrap the wired router and just use a wireless router. Two routers need to be bridged when connected. I guess you're using your router as a switch!!

What's so complicated The best thing is to just use a wireless router.

I have a wireless router with 4 computers and n mobile phones.

You need to give the address of the computer to the wireless router, then connect the two computers to the wireless router, and the address will be obtained automatically.

Replace 1 wired router with a switch.

If you are connected from someone else's house is a network cable, plug the incoming network cable into the WAN port of your wireless router, desktop LAN port, and then open the browser to enter into your wireless router, the account and password should be admin, specifically look at the router manual, after entering the router page, set it according to the manual, your situation should be dynamic IP mode, and then set the wireless security password, and finally change the gateway to your WAN port settings, save the restart route, That's it.

The number of people used on the route is limited.

1) If it is a problem with the broadband itself, first directly connect the broadband network cable to test, if it is a broadband problem, contact the broadband customer service to solve it.

2) If it's a problem with the router, if it can be used originally, it can't be used for the time being, my own practice is to roll high and disconnect the power supply of the router when plugging it in, and I'll take a look. In there is a factory reset, it can be used from the new settings (this is under the premise of the correct physical connection, sometimes caused by the router's slow or failed IP address search, not that the router is broken).

If it can't always be solved, it is recommended to call the customer service of the router, they have **** guidance, I encounter problems that I can't solve, it is very useful to consult the advice they give, and they will give correct suggestions for your settings or operations.

3) If you turn off the wireless switch, turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4) If it is caused by a system problem, it is recommended to restore the system or reinstall it.

I practice mobile phone or other computer can access the Internet, not necessarily your computer can access the Internet, the method look at the above, if you have any questions, ask me.

5) If you have any questions, please ask me.

Disconnect one, connect one.

Check the router settings to see if DHCP is enabled, if not, enable it. The other two computers need to be set up to automatically get an IP address and an automatic DNS address.

You see if the driver of the wireless network card on the computer is normal.
