What to do if the phone distributes an access point, but it is not visible on the network?

Question

Computer networks

The bottom line is this: I have a wi-fi receiver on my computer, the Internet is distributed from the phone. At one point, the receiver stopped seeing my wi-fi from the phone. The problem was solved mechanically without my intervention. Now the problem is relevant again and causes concern, because: wi-fi from the phone cannot be seen by other devices in the house (2 laptops and the Internet works the same way, only not through my phone, phones also cannot see the dot). I tried to demolish the firewood of the receiver on the PC, tried to demolish the phone settings (twice), switched the access point hertz more than once (on my phone it is possible), demolished the phone data and downloaded the backup copy. And all to no avail. The question is not an easy one, I could not dig the material myself. Thanks in advance to everyone who does this.

Note: The Wi-Fi analyzer was able to find my point, only it fails after 3-5 seconds, and in order for it to be displayed again, it needs to be rebooted. 6 channel. There are no overloads.

Answer 1

After all the manipulations and checks, everything converges on a technical malfunction of the module. 3 days in the service will confirm or deny this information. thank you for your responses

Answer 2

To get started, check the congestion of wi-fi channels. Also see if the wi-fi module is alive on the phone.

Answer 3

Wifi scaner or inssider search
Either manually enter the name of the point and password on the devices, perhaps on the phone there is a checkmark to hide the network or something like that

Answer 4

Clearing the list of points / passwords saved on the laptop once helped me in a similar situation.

Answer 5

Try to connect manually by SSID. If even this does not work, then the problem is either in the module or in the firmware, especially if there is some kind of custom curve. And yes, what kind of phone, firmware. ?
