Thanks for the response, Geoff!
No, i did verify that the ethernet cable was plugged in correctly into the right socket
But whats strange is that i'm unable to get to the point where i can turn off DHCP. Is it that it automatically detects the router setting, and switches to DHCP ON and won't let users turn it off?
Also i found out another issue - no subwoofer tone
The amps look to be ok. I ran audyssey last night, and it was able to detect all the attached speakers except for the subwoofer.
Well teaches me right for buying stuff on craigslist. I'm afraid that the repair costs might be more than what i paid for the unit... labor costs are mind boggling in this country.
