How to improve bad wifi in a hotel?

Question

WiFi

The hotel has 5 floors, each with two routers with the same ssid. When searching for a network, it shows a signal of 100%. After connecting, the signal drops to one division. It is extremely unstable (sometimes partially) and loads pages slowly. The operator that connects the hotel to the network provides high-quality and fast Internet, but something terrible happens through wi-fi. There are suggestions that all routers work on the same channel because of this "noise". The hotel is half empty. Thailand country. Is there a way to affect the quality of the network. Maybe some tricky settings are needed when connecting? Thank you!

Answer 1

For Windows, there is the InSSIDer program that can tell you where to dig further if you know what to look at.
Draw for yourself an approximate network coverage map, if the routers work on the same channel (it can automatically change depending on the background), force it to be set to different ones. Look at what can degrade the signal quality (material structures, overlaps). Try to calculate the optimal point locations. Check whether one DHCP server gives all addresses and the other points are configured correctly. Which of the ways to organize a wi-fi network do you use? ( can be read here ) it seems that you need WDS.
Well, collect more data to investigate the problem.
If all these measures do not help, look towards ready-made solutions for such tasks, for example, unifi points . At one time, I really liked the possibility of their configuration, control for the office with more than 100 wireless devices. But in this case, you will need a server where the web muzzle will be installed to configure and manage them.
