Last night we had a near lightning strike that I believe toasted my Inspiron 660 integrated 10/100/1000 Mbps ethernet adapter.  I just need some confirmation that I am correct and that the only option is to buy a new adapter.

Evidence:

1. There is no link light

2. The device manager no longer shows the wired adapter

I tried disabling and reenabling the LAN device in the BIOS Advanced devices. It had no effect.

Fortunately the wireless adapter still works but I'm a hardwired kinda guy and I like my internet by wire.
