I'm specifically thinking of a router without a modem as I'm happy to leave the HG612 in place. It's my TG582 that needs replacing so if I could reduce the box count at the same time, so much the better.
Looking at Draytek - 2925 series only gives me one extra port.
Ah, I just noticed the 2925 is 5 ports plus 2 WAN, not sure if one of the WAN ports can be turned in to a LAN port also.
So that leaves the 2860 with 6 ports and modem built in that you do not need or something like D-Link DSR-250N with 8 ports but only wireless N.
There is however a new Router coming out from ASUS with 8 ports -
