I have netgear n300 router which I had installed about 6 months back.

Here is how the setup is, I have a local internet provider by the name of "Hathway" they have this modem which is in turn connected to the router and a wire from router is connected to my desktop.

As shown in this pic below, except for the laptop I use a desktop rest all the connection is same

So with this connection and the below configuration, every thing worked fine. The desktop would work also all my laptops and mobile devices would connect and be able to access the internet without any problem.

Now suddenly since yesterday (with no changes made whatsoever to this config) all my laptops start showing the limited connection message and cannot connect to the internet.

However the desktop which is connected can access the internet.

Can someone please guide me on this.
