One of the most common problems we wi-fi users have is the occasional speed bump. As it is going well in your first condition, after a few days it will be slow again and I will show you some of the reasons for it.
1. If there are more users, the speed will be slow
At first our wifi is connected to 2-3 mobiles but as the day goes on in the user bar. If your wifi is 1-2 mbps, you must not connect more than 4-5 devices. Then it will be slow, especially if everyone runs together. Or a lot of times when you give a password to someone, he gives it to everyone again, so the user bar keeps going, so go to the admin panel and see how many users there are and block those who have the bar.
2. If not taken directly from the company
In fact, many people start a business with a WiFi line, such as a line with different homes and if they want 4 mbps speed, then it is reduced to 2-3 mbps, so they take 4 mbps from you in the office 2-3 mbps money. Will submit. So even if the user is low, if you do not get the net speed as you go directly to the office. And tell them your username and ask how many mbps you have been given.
3. wifi signal but do not run net
Occasionally the router hangs, so open the router's charger and plug it in again. If it doesn't work,
many times someone can enter the admin panel and do everything upside down, so the net can go. Then you can reset your router and setup the router anew. If it still doesn't work, call the office or there may be a problem with the fiber or your connection.
