Why does the computer on Windows not connect to the phone in Wi-Fi access mode?

Hello, I read your article and tried the repair. I have a Huawei 4G phone, I use a PC on Windows 7 through its distribution, about 4 days ago the Internet stopped turning on, in the morning and went down in the evening, I leave with the phone and back can’t connect to the network, the tel. as a modem works. I have a second 3G phone from it immediately connect to the PC, but the speed of 1-2 Mbit/s. It is very low, 4G speed is about 10 Mbit/s and it was enough for me to work.

I have a program speedtest and on the PC with 4G speed 10 and 3G less than 5. Here I also thought that 4G is from China and the signal from the tower is different? The signal from the phone 4G antenna 3-4 divisions, so that’s why it stopped connecting to Windows?

I uninstalled the network adapter twice, changed the connection passwords.
reset the hotspot settings on the smartphone.
disabled antivirus.
tried connecting in safe mode and wpa2 psk.
rebooted and removed the USB adapter itself from the PC socket.
I called Huawei and they said that I bought it in China and reset the network settings, but it didn’t help.
I haven’t yet gotten to the vinda and its realteka, because the same SIM card from another phone immediately connects to the network.

And it’s not clear why 4G joins as spontaneously, but today all evening I’m doing scientific poking and can not connect the smartphone 4G, error Windows failed to connect to the network wi-fi. Can you give a tip is the provider, vinda, or maybe the phone? Thanks in advance.

Addendum:

In general, I sat with this problem 4G does not connect to the network for a long time, and here the network connected as if spontaneously once again, I try to flip browser pages they kind of jump unnaturally but flip, turn on speedtest to measure the speed of the Internet, the Wi-Fi icon is connected, but the speed does not measure. Connects and suddenly gives an error in English. that the firewall may be blocking, etc., went to the firewall and disabled TP link in the firewall and all networks. By the way, I wonder if all the checkboxes in the security of the firewall are correct? Well, after that I measure the speed and everything is normal above 10 Mbps, so far so, maybe there will be some more surprises.

Answer

Hi. It is very difficult to read your message, I could hardly understand it a little bit. I couldn’t understand a lot of things from your description of the problem.

Do I understand correctly, that the 4G smartphone internet connection is working now? Is your computer already connected to the network normally?

Theerror “Windows failed to connect to wi-fi” can appear for various reasons. Both on the part of the computer itself and the access point.

The first thing you had to do was to start a Wi-Fi hotspot on your phone with a new name and password. In the name and password use only English letters and numbers. And on the computer to make a reset of network parameters.

Well, to find out what’s wrong, you can simply connect to this Wi-Fi network (which is distributed by the phone) another device.

Now very popular topic, when operators block the distribution of Wi-Fi from smartphones. But this is hardly your case, because there is usually a connection to Wi-Fi, the error “Windows failed to connect to wi-fi” is not present, but the Internet does not work.
