Wi-Fi continually dropping

Hey there Dell Forum Community.

I have been having an issue with my Dell Inspiron 15 7000 Series laptop connecting to my router. I know for a fact that it is the laptop and not the router because on Dec 24th, I had a technician from my internet provider come and fix the internet. Now I am getting the 25 Mbps that I pay for. Anyways, I got this laptop as a Christmas present from my parents, and I love it very much. Unfortunately, as I have stated, it is having a terrible issue connecting to the internet. If I am anywhere in the house other than right in front of the router, the connection will disconnect less than a minute after connecting. First the wireless connection symbol shifts to the limited connection symbol, and then it goes to the no connection symbol. I then proceed to go to the network connection list, and my Internets SSID is clearly displayed there. I also have the network set to automatically connect, but it doesn't.

Also, I read on a post located in this section a few minutes ago about setting the power options for wireless to maximum performance. It does not seem to help.

Can I please get some guidance as to what I can do to fix it? Or should I just have my parents replace it with a different laptop model.
