1. Restart the router
Yes, that's what they advise you to do first of all when contacting the support service. And quite correctly.A modern router is a complex device, in the operation of which software errors may appear over time. The easiest and fastest way to get rid of them is to reboot the hardware
2. Move the router
Do you keep the router in the closet? This is not a good idea. Walls, cabinets, and even bookshelves can weaken the Wi-Fi signal. There is no universal place for a router, but try not to put it in a corner, under a closet or in a desk drawer. It is necessary that gadgets that do not require such a high connection speed, for example, intelligent temperature controllers, can be pushed a little further.
3. Turn off all unused devices
Connecting multiple gadgets to a Wi-Fi network at the same time can create a lot of problems. Make sure that the really necessary devices are using it, and not the smart kettle that you have never needed. High-quality routers, for example, all of the above allow you to determine the priority of devices and services.
