Devices Connect to Wifi, but no Internet Connection

DISCLAIMER: This is my first post so I apologize for any mistakes I make.

Hello all,

Yesterday morning upon waking up I discovered that the Wifi in my house was no longer working. It had worked fine the day before but stopped working completely overnight. At first I thought it might have been Charter Communications (My ISP) throttling the internet due to our bandwidth (My Mom watches a TON of Netflix). But the internet works fine with our two home desktops. It is the same connection but devices such as my iPhone 4, Nexus 7, iPad 3, iPhone 5, etc. are unable to get internet access. They are able to connect to the wifi and you are able to see the bars, but when trying to connect to the internet you get a network error message.

To try to fix this problem I ran measurmentlab (test for throttling), my virus scan (McAfee), and malwarebytes. I was unable to see any noticeable change in my problem.

I am hoping someone might know what I am doing wrong, but I haven't been able to find a thread that has helped me out thus far.

Thanks for reading, Nick
