I've got a problem with my Internet modem. When I connect the modem directly to my computer and run a speed test, I got 15 mbps when it should be 25 mbps. I then set the LAN card to use "100BaseTX Full_Duplex", which increased the speed to 22 mbps, which is acceptable.
However, when I then put my Linksys WRT54G into the mix, so that the Internet goes to the modem, then my router, and then my desktop (all wired), then the speeds drop back down to 15 mbps, even though I still have "100BaseTX Full_Duplex" in use.
Do I have to enable 100 Full Duplex on the router somehow? If so, how do I do that?
