Hi my dad has old sony vaio laptop - Sony Vaio SVE151C11M, he uses it just for internet browsing. For some reason wifi stopped working, it shows all wifi around and connects without any problem but after it connects it says NO INTERNET, and it changes all the time for 5seconds it works for 30 seconds it doesnt. I have reinstalled it from win 7 64bit to win 10 32bit hoping it would help but still the same problem.
