WD TV Live Plus won't recognize laptop anymore

So, I’ve just moved and for some reason my WD TV will no longer recognize my computer. I have not changed any of the settings on the WD or my computer. I never had a problem before this. It is recognizing my roommate’s computer, and the two have never been connected before this. I’ve tried pretty much every troubleshoot I could find and still nothing. Any ideas?

Could you provide some more details about your network? Are you using DHCP on the router? Is the computer getting the same internal IP as it used to? Are you connecting the WD TV wired or wirelessly?
