Hi Fatima, Welcome in Community
In first instance, if your computer MSI is new one, you should refer the problem with the retail vendor for you dirict of warranty.
Then, do you tried to reset completely the network? If not, do it in this way:
Press WIN + X and open terminal as admin, now type
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
Restart the system and let me know
