I have this problem and I was hoping someone could help me. I have a wired-only Linksys router connecting my PS3 and PC to the internet. For a few days now, every 10 minutes I get this message - Ethernet cable disconnected. It lasts 3 seconds or so and it goes back to normal. But the thing is if I am playing online, I leave the game, get disconnected from the PSN, etc. and have to do everything to get back in again. Not to mention I cant play since it happens so much, Now I think it might be something about my PC and not the PS3 or router, because whenever I play online with my PS3 when my PC is off, this doesn`t happen. Or happens only 1 time. So can anyone with PC knowledge help me? Thanks in advance. PS - I should say that this message appears on the PC too. So it`s not only a PS3 online problem.
