The problem is that your gateway and DNS have the same Ipv4 address...192.168.1.1. Each device should have a separate address. So there something wrong with the way the network is assigning those address to each device. I would try resetting the router by unplugging it from the AC outlet for one minute and plug it back in. If that doesn't work, use the reset button on the back of the router. It's a little tiny hole with the reset button inside. You will need a paper clip, insert one end of the paper clip inside the hole and hold down until the router reboots it self. This will reset the router back to factory defaults.
