Hi all, After a few recent and probably Denon AVR related network glitches on my 3310ci, I thought I'd look into replacing the NIC. MCM Electronics sells one for the 3310ci, 8r1891001200d, for $150.74. Hoverver, that NIC is not currently available and is on back order. MCM also sells the NIC for the 4311ci which is DM860 SUB ASSY AVR4310CI DM860 SUB ASSY AVR4310CI 8R1891001100D for $131.19. This one is currently available and costs a bit less. So, my question to any one in the know is are these parts interchangeable? And could I perhaps use the 4311ci NIC in place of the 3311ci NIC? Thanks for feedback.
