Just some ideas on stuff to try. It is strange that the TV only seems to show a MAC while it's successfully connected.
No luck with the router, either.
I called LG and spoke to a technician. Unfortunately, they told me that I can't get the TV to display a MAC address unless I'm connected to internet. Since I can't connect without a MAC address to the campus network, this creates a "nice" chicken-egg situation.
If it was something other than a big, heavy TV, I would have taken it to my friends place and get it connected to internet, but it's just not feasible, especially since I only want this to be able to update firmware (not to use the Netcast features - I use the BD Player for that). Is there a way to update the firmware through USB connection, etc?
It's just puzzling that a "static" number such as a MAC can't be retrieved. It's not like it changes every time I'm connected to network.
