Notebook suddenly having problems

Hello, I bought a Aspire V15 Nitro Black Edition (Model VN7-591G-74SK) last year on November.

 

First problem is that the Fn (function key) stopped working suddenly. 

I cannot change volume/brightness and other things that I used to do easily with the function key. 

I do not know if this helps looking for a solution, but the keyboard light turns back on when I press the Fn key (The lights go out when I am idle for some time). Does that mean the computer recognizes that there is a key being pressed, but does not what the key is supposed to do?

 

Secondly, I have been having problems with my wifi connections. 

I was able to smoothly connect to wifi and have no problems. I decided to stop using wifi by hooking up to my modem. A week ago, I decided to start using wifi again, but I wasn't able to connect to the connections I used to use. After numerous attempts, I can connect, but it stops working randomly, giving me the error code "dns_probe_finished_nxdomain" or "dns_probe_finished_no_internet" on Google Chrome (On firefox, it just tells me that the computer cannot connect to the internet).

 

Please feel free to ask about something if my post seems ambiguous. Thank you, and I hope to fix these two problems ASAP.
