Can two wi-fi router active at same place can disturb each other and slow the interent speed on wi-fi?

I have an Airtel ADSL+Wi-Fi Router and Mi 4C Wi-fi Router at home. Wi-fi of both devices is on. Should I disabled Wi-Fi of my Airtel Binatone modem?

I want to use my Mi Wi-Fi router as a main wi-fi hotspot.

You can put them on different channels to avoid interference

Bigger problem is cordless running on old tech.

Rajneesh is right, configure both routers to use different channels.

Routers usually pick a less crowded channel on startup unless manually configured. If you want to do it manually, there is an app named 'Wifi Analyzer', it will show all the channels in use so you can pick a less crowded channel.
