Is the cable modem plugged into a: hub, switch, directly into the PC with crossover? If the connection doesn't involve a switch of some type, I don't know that it's possible to get full duplex. I've seen hubs and crossovers do ONLY 1/2 duplex and I don't think it's possible to do "full-duplex" with a 10Mb connection, which is what most cable modems seem to have on the ethernet port. What are you considering "a high rate" of collisions, 5%, 10% more? Some collisions will always occur, even with a switch. If you have a 10/100 switch, the collisions will occur simply because the computer will try to shove 100 pounds of fries into a 10 pound bag. I really don't have a way of knowing about how the NIC is running in full-duplex or not. With the NetGear 310-TX we use, the driver suggests which "mode" it's in, 3Com gives some useful data, but no hard and fast rules. Does this help?

I was looking through the specs on the modem and noticed it is half-duplex. Is there anyway to set/check the half-duplex status on the NIC on my linux router. > > _____________________________________________________________ > Domain powered by www.iReg.com > E-mail powered by www.1FreeEmail.com > _______________________________________________ > tclug-list mailing list > tclug-list at mn-linux.org > https://mailman.mn-linux.org/mailman/listinfo/tclug-list > -- ________________________________________________________ ReadyNET Go!, Inc. - Building your Business on the net ________________________________________________________ Mark J.
