This is the first problem like this I've encountered with my console. In my room I have my modem, and I plug it into either my laptop or Xbox depending on what I'm using at the moment. I had a router set-up, but it failed and died, and I've not bothered with a new one yet.
Last night I was watching Netflix on my console when the screen suddenly froze. I restarted my system and tried to connect, but I'm receiving a "Cannot obtain IP address from your router or modem error." My XBOX has always connected with a wired connection, and has always been set to automatically configure its IP.
When I plug the ethernet cable from the modem back into my laptop, the network works fine, of course. I've tried to read the guides detailing how to find a static IP and set that manually, but they're pretty much all PC-intensive, and my computer I connect to the internet with is a Mac.
Anyone have any ideas why my console suddenly cannot connect, or how to remedy this? Could the console itself be faulty?
