Wired Connections Gone

[maineultraclassic]

I came from work today to my wired connections all dead. That covers my desktop, my MagicJack phone, and my DirecTV connections.

I tried unplugging the router for a minute then plugging it back in, that worked at first, then a little while later they were all dead again.

The wireless is working fine, just the wired are dead.

Router is about a year old, and it's running the most current firmware. I have noticed lately that it won't show me the attached devices, but that's the only thing weird lately until this.

Any ideas on how to fix this, or is it toast and time for a replacement?

Thanks,

Steve
