Hey guys. Long time lurker, first time poster
I have BT Infinity Option 2 and I'm lucky enough to get the full 80/20. When using the BT Home Hub, all the wired computers download at around 75-80Mbit/s. When I replace the Home Hub with a Cisco/Linksys WRT320N running DD-WRT one of the computers drops to 60Mbit/s. The computer that has this problem is a newly built Hackintosh, dual booting Windows 7 and OS X 10.8. The problem is identical in both OSs. All cabling checked, as well as trying a different Ethernet port on the router. What the hell could be causing this? All I can think of is that the WRT320N doesn't like the HP NC360T Dual Port Gigabit NIC in the affected machine. But why doesn't it have a problem with the Home Hub?
tl;dr: Internet fine on all computers when using Home Hub, slower on only one computer when swapped for what should be a better router.
