The problem is wifi keeps on connecting and disconnecting. It's always unpredictable. Whether on mobile phone hotspot or on institute's wifi, only my laptop faces this problem of intermittent connectivity. All other devices (phones, laptops) of my classmates connected to the same network (even on mobile hotspot) shows seamless connectivity. Only my Thinbook 1310 keeps on connecting and disconnecting again n again. When it would get connected n when it will disconnect is always unpredictable. That's why as per my opinion, the problem lies with the hardware n not software
Also in the settings is an option to Update Driver. Use the ethnernet connection tto let Windows wander round the Net to find the right driver.
