The i9100 signal is not very good in the first place. If you still have no signal when the signal is particularly good, it is recommended to go to the repair point to see if the signal copper sheet of wifi is not in good contact.

If someone else's signal is particularly good, you still don't have a signal, it is recommended to go to repair, if you are in Guangzhou, I can help you take a look!

Hello, according to the problem you described, it is recommended to follow these steps:

1.Select Delete the connected wireless router on your phone (tap your finger lightly on the name of the wireless router at home and select Delete). 2.

After the router is restarted, open the mobile phone WLAN settings (Settings - Wireless and Network - WLAN Settings - WLAN Tick) to automatically search for wireless signals. Check that DHCP is enabled on the wireless router to see if the phone can access the Internet normally.

3.If this phenomenon still occurs on the mobile phone after doing so, it is recommended to change the wireless Internet protocol of the router: if the wireless Internet protocol is recommended, if the wireless Internet protocol is recommended.

It may be caused by the compatibility between the wireless Internet protocol of the wireless router and the wireless Internet protocol of the mobile phone.

4.If it still cannot be used normally after operation, it is recommended to use the router more sharply.

I hope the above reply is helpful to you. Thank you.

I have the same problem with my android phone, but QQ can be on. However, I can access the Internet in other people's homes, which is more depressing.

Encountered? I thought there was something wrong with my phone! Now you know!

Someone has the same problem as me! I haven't been able to find the reason! Maybe it's what a friend on the first floor said!

I'll be reconnected after a while when I encounter this situation! Sometimes it's just a matter of getting back on! Sometimes it doesn't work for a long time!

You try it in a different place first! To the café! If not yet!

Most of them have problems with their phones!

It depends on what kind of network you are connected to, your own home is easy to do, and there are bars, coffee bars, etc., which may be better, if it is someone else's network, then it is not clear.

There are a lot of this situations, the most common is the Chinanet signal, it is PPPOE dial-up Internet access, the signal can be connected to everyone, and you can connect to it, but you can't access the Internet, of course, if you can access the Internet, the telecom people are eating dry food.

Dear users: Hello!

According to your description, if you have a similar problem, you need to check the router interface, connect to the incoming port, and restart the router. If the above does not solve your problem, please call 10000 and consult customer service staff to help you solve it.

The wifi connection only means that the wireless function of the router has been turned on, which does not mean that you can use broadband.

Wireless devices connected to the wireless LAN can only access the Internet through the router if the router is connected to the ADSL and connected to the Internet. As shown in the figure below:

The normal wifi of the mobile phone can only mean that the mobile phone has been successfully connected to the wireless LAN of the nearby hotspot, and only when the router dials up successfully, the device connected to the wireless LAN can access the Internet through the router.

Restart the routing at home and try it, that's what mine is.

Set the authentication type of the wireless router to WPA, the encryption algorithm to AES, the mode to 11BGN Mixed or 11BG Mixed, and the maximum transmission rate to 54Mbps.

Maybe you didn't turn on your phone's search wifi function.

1. All: If you are sure that your mobile phone has checked the wifi (the mobile phone system is connected to WLAN), then you pay attention to whether there is an open WLAN around
