As time moves on I find myself moving away from all in one devices.
I now keep my wireless separate from the router and just run an access point. A Dlink DAP-2660. Lots of nice advanced features to play with.
It's basically transparent to my internet connection. Though for moving gigabyte+ sized files like bluray MKVs I hard-wire everything.
If 10gig-E would come down in price if be all over it.
