said by BluffingJ:I have already returned that router, so that's irrelevant.As is, it would still be the same connection right?Which means no problem is fixed except the router changed.If it is a signal issue,coax cable or otherwise, wouldn't that still be there because it is infact the same signal?
physical connections maybe the same but it's the configuration / settings within the modem and router that will help you figure out if it's the router that's dropping the signal or the modem.
the SMC is a modem and router in one, so when you added that router it created a double NAT which is not desirable and may not work properly network wise. it's not as easy as just connecting a belkin wireless router to that SMC.
what I did with mine was to connect 2 wireless router acting as access points, that way I get good coverage in any corner of the house and even outside.
and that Wii console is better off on a hardwire connection...I had mine on a wireless connection before and it sucked...bought a usb/ethernet connector for wii and boom...problem fixed.
