The Lenovo Y485 wireless network is always limited

Sometimes it's a problem with the wireless signal, you can find the signal, but there will be an exclamation mark on the signal, saying that it is limited, in fact, the wireless signal is very poor, you can connect to the Internet, but the signal is unstable, and it is very stuck.

Dear Lenovo users, hello!

If your problem is not solved, you can complain, put forward your valuable opinions, and then transfer to manual service.

You try the following:

My Computer->> Right Click-> Manage-> Click "Device Manager"-> Network Adapter-> Double-click on the wireless network card-> Click Power Management in the pop-up window-> Check "Allow the computer to turn off this device to save power" -Confirm.

Sometimes a reboot is required.

Maybe it's a system compatibility issue. The compatibility of the Wi7 64 has always been unsuitable. Win8 will improve??? I don't know.

Dear Lenovo users, hello!

It is recommended that you update the network card to the latest version of the driver to find it, set the correct wireless network connection mode, if it still does not work, you can consult our engineer **** query.

Dear Lenovo users, hello!

The solution to the Lenovo E435 display network restriction is as follows:

1. The wifi itself is a problem, the wifi may not be connected normally, resulting in the inability to access the Internet;

2. Router problems, the router may be overheated or damaged;

3. There may be broadband arrears, resulting in inability to access the Internet;

4. The wifi name contains Chinese, resulting in some computers unable to connect to the Internet;

5. Computer system problems, there may be problems with the system, resulting in connecting to wifi but unable to access the Internet.

Suggested workaround:

1. Use other mobile phones or devices to connect to Lvsen Talk Wifi to try whether you can go to the Spring Year Network and eliminate the problem of WiFi itself;

2. Restart the router to try, or restore the router to factory settings, then dial up the Internet again, and reset the wifi according to the setup wizard, or change to a new router and dial up to connect to the Internet;

3. Contact the broadband customer service to confirm whether the broadband is abnormal, such as arrears, recharge the broadband, and then dial up the connection;

4. If the wifi name contains Chinese, it is recommended to modify it to English or a combination of English and numbers before connecting;

5. If the above reasons are ruled out, it is likely to be a computer system problem for a long time, and it is recommended to restore the factory settings. See if you can tear it down and solve the problem.

The speed of Internet access is not unrelated to the software and hardware of the computer or mobile phone, but it has little to do with it. It's like you usually only hear people complain about the bad signal, but you don't change your phone or computer because of it.

The speed of Internet access is mainly related to the following factors:

One is the transmission medium; The second is the transmission rate. At present, the medium of the backbone network is optical fiber, which is the best medium at present, and most places have realized optical fiber to the home, so the medium of the backbone network is beyond question. The problem is that the quality of the indoor line is worth it**, although it has been fiber-to-the-home, but the network speed from the indoor to the terminal is 4m.

In addition, the transmission rate is related to the service provider, fortunately, China Mobile has entered the 4G era, and other service providers have also reached 3G and are actively moving towards 4G, and are improving their network speed, which is also good news for users. But China's internet speed ranks 98th in the world, why? I think most of the reasons are:

First, the line is aging, the quality is not high, the layout is unreasonable, and the key is that the "last mile" problem has not been solved; The second is that the maintenance service can not keep up, many service providers only know the charge, but less service quality improvement; Third, from an objective point of view, China has a large number of users, and there are relatively many problems of network congestion, especially at 8-12 a.m. and 3-6 p.m. during the peak hours of Internet access. It is recommended that you avoid rush hour surfing.

Good luck!
