Overheat caused problems connecting to internet?

[Rcolpo]

After a hot summer in Rio de Janeiro the wifi connection started to fail on my Samsung NP350E7C laptop. Although it was apparently connected to the router it was unable to exchange data. At the beginning it only happened once in a while but now internet rarely works. I was convinced that the summer heat created a malfunction in the wifi hardware, but I just notice that I´m also unable to connect to the internet using my cellphone to share connection with my laptop via USB. So, I´m USUALLY unable to connect to internet either via wifi and USB. Is this most likely a hardware problem? If so, changing my laptop's wifi hardware would solve it?

have you tried reinstalling laptop's software/system drivers?
also call your ISP and have them check the router/modem.

have never had high ambient temps damage a component through our 100+°F summers so i would doubt that has caused any issues on it's own
