Why can t my laptop connect to the Internet with limited routing

First of all, Wi-Fi won't affect your wired connection, so don't worry. If it doesn't work to plug in the line, first plug the network cable independently into the notebook, and then dial up, which is to establish a network connection, try to go up, if you can go up, it is a problem with the router settings. If you can't get up, it's your computer driver or setup problem, your computer should be new, right?

If you buy it and don't go to the Internet, it may be a problem with the network port of the notebook, or an internal problem.

It's a coincidence, I also use Y550, I bought it in June today, and the first thing to tell you is that there is no half-dime relationship between the wireless network and the local network!! If you want to turn off the wireless network, you can press the function combination key on the laptop keyboard fn+f5 will pop up a dialog box should be the wireless network card and Bluetooth switch option, directly select to turn off. Or right-click "My Computer", select "Manage", then double-click "Network Adapter" in "Device Management", and select "Don't use this device", may you succeed!

Because we all have a common choice.

Wireless and wired generally don't affect each other, are you sure that the local connection is connected and not restricted?

If you are connected, you should be able to access the Internet, and you can try it according to the network settings when you surf the Internet on your desktop.

You unplug the network cable of the online desktop and connect it directly to the laptop to try to change the IP settings according to the desktop online, if not, you can't explain the problem in detail, or directly find someone who will do it, which is more convenient.

A wireless connection must be available in an environment with a wireless network. If you are in a place where you don't have Wi-Fi coverage, you won't be able to access Wi-Fi.

Is it a driving issue? Try a different driver.

Secret 1: Enter the wireless router management interface with wire, confirm whether the wireless function of the wireless router is turned on, whether the SSID is hidden, if you choose to hide the SSID, you will not be able to search for the network name of the wireless router, so do not choose to hide the SSID if there are no special requirements. (When the wireless function of the wireless router is turned on, the wireless Wi-Fi indicator is on).

Tip 2: If you are a friend who uses a laptop, please make sure that the wireless function of your laptop is turned on, if not, please turn on the wireless function of your laptop.

Tip 3: Change the frequency band of the wireless signal to between 1 and 11, because some wireless network cards may not support the frequency band. Here's how.

Go to Device Manager == >> Network adapter (the network you are using) Right-click Properties ==> Advanced == >> Network Card Address ==> value is set to 6Then set the route wireless connection band to 6, save, and it should be ok pulled.

Tip 4: Adjust the position of the wireless router or wireless network card to avoid the situation that the wireless network card is in the signal blind area of the wireless router.

Hope it helps.

Make sure your network card is not broken, and reload the horse. If your wireless network card is broken, how to get on the signal if you can't receive it, the question is whether your wireless network card is broken, and your colt is not displayed when you plug in the network card.

See if your wireless switch is not turning on. Generally fn+f5Look at the wireless logo on your laptop on that key.

Either your wireless network card is broken, or you need to upgrade the network card driver.

The network speed may be relatively slow, and I often encounter this problem, and QQ will not be able to log in. You can also see if there are any problems with the network settings.

Mine too, ahhh

If the NIC is faulty, we recommend that you upgrade the NIC.

If your companion can use wireless but you can't, and your computer can connect to the wireless network in another place, it means that there is no problem with your wireless network card and driver, and it should be a problem with the router or your computer's IP settings.

1. Restart the router to see if it works, if not, check if your IP address is in the same network segment as the router, if not...

2. Change the manually set IP to automatically obtain the IP, and there is no problem with the computer IP setting.

3. If you still can't access the Internet, please confirm whether the router is set up with "MAC address filtering" and "IP address and MAC address binding", if so, then add your wireless network card MAC address or delete your MAC address according to the MAC address filtering rules.

4. If it still doesn't work, reset your router, PPPOE dial-up, DHCP on, wireless encryption, and no need to set MAC address filtering These security measures.

Forehead. Is it your own home? Can a companion even you can't? I haven't encountered it, is it incorrect, see for yourself whether it is the same network segment IP, and also look at the IP connected by your companion.
