Where does wi-fi go?

Question

ASUS

At home there is a Wi-Fi router TP-LINK TL-WR841ND. I recently bought an Asus UX303Ln laptop, after which I noticed that the Internet was constantly falling off. Writes: connection without access to the Internet. On a stationary computer, via cable, there is Internet. And it disappears on phones and laptops. It feels like the laptop is killing Wi-Fi.
Updated router firmware. Did not help. What other options might there be?

Answer 1

Agree with Pavel. I recommend installing Wi-Fi Analyzer (for Android) on your smartphone, there will be an "Eyes" icon in the upper right corner. Select the "Rating of channels" section. You will see a list of channels from 1 to 14 and opposite the rating star. The more stars, the less customers on this channel. Those. choose the channel with the highest number of stars.
Next, on the router, Wireless mode - Wireless settings. Select the Channel section and set the appropriate number. Save the settings and reboot the router.

Answer 2

It is possible that just the communication channel on which wi-fi works is overcrowded. Try to change the communication channel, it is better to use 1, 6 and 11.
