For several months I have had a problem with the Internet - every few or several minutes it turns itself off (a triangle with an exclamation mark appears) and after a while turns on (manual turning on and off also helps). The problem intensifies when using wifi on more than one device.
The supplier is Orange, I called them, they say that everything is fine on their part, if I want it they can replace the router for me, but unfortunately no one knows where this one has broken from them, or where the one we are using today, i.e. TP-Link TD-W8950N.
I was looking for a solution, but I did everything I could, i.e. router hard reset and it did not help. In addition, after this reset on my laptop the internet does not work at all (a yellow triangle with an exclamation mark is still displayed), and on other devices it does. The networks also display information about an unidentified network, I don't know where it came from:
Can you help me restore the connection to my laptop?
Or maybe someone knows a solution to the main problem, which is disconnecting the Internet?
I will add that I don't know much about IT, so if you have any advice, please, step by step.
