Earlier today the wifi suddenly stopped working while I was online. I wasn't doing anything extensive, just browsing. The ethernet cable works just fine so I know it's not the internet itself just the wifi. Also, it's not my laptop as another laptop and kindle are unable to connect as well through the wifi but the other laptop can also connect through the ethernet. Is there anything I can do to try to get it working or is the router just burnt out and I need a new one? It's a few years old, a Cisco brand. Thanks.
