Can you confirm that you have the PC's MTU set at 1430 (or lower).
FWIW I've never found any reason not to set the router's MTU at the maximum (1500) and then just adjust the PC's MTU (if the routers MTU is larger than the PC's it isn't going to stick packets back together!).

The MTU of all my PlusNet connected PCs is 1430. I can understand your puzzlement about setting the router MTU to 1430 since the PC's MTU is what matters. Whatever, the result is almost no packet fragmentation. In fact, I have never actually been aware of packet fragmentation.
