Sony bdp s-270

[Snarff]

I have had this playe close to 2 years now and last night I found out it no longer plays Universal titles. Upon further investigation I found out it would not play any 20th Century Fox titles also. Tested other bd's for about 30 min and found out if I disconnect the ethernet cable everything works pretty good, maybe takes a little longer to start playing Universal and 20th Century titles. I checked for update and there is none. Has anyone else experience this and know how to fix it. I watch netflix a lot and I really don't want to disconnect internet each time I watch a disc

Thanks
