I have a RT-N66U with Shibby's Firmware 1.28.0000 MIPSR2-112 K26 USB AIO-64K. I previously had a Shibby K26RT-N build 112 and had this same issue. My guess is that it is not build specific.
My setup is cable modem--->VOIP(Ooma)---->router. About once a week the internet connection drops even though the modem has a connection. My modem always says I have a connection. To get the connection back all I have to do is reboot the router and I good for about another week. For whatever reason...
