Hi Sake, Not an unreasonable suspicion - in fact, when I used: http://miranda.ctd.anl.gov:7123/ The site suspected a duplex mismatch since my download speed tends to be less than half of my upload speed. Many times the upload speed is close to the advertised rate but I have never been able to get the full download speed.
Maybe I can double check with the provider on their router - but they said they already checked everything and the service provider seems decent. Still, it's probably worth double checking. On all my equipment, there are no errors/FCS, drops, out of buffers - everything is perfect (from an Ethernet stand point anyway). The newer stuff is gigabit where the IEEE mandates auto-negotiation in the spec. The older stuff that's 100 Mbps is hard coded just like you said. I guess if it were easy there wouldn't be a whole IT profession, eh? :-) --Jim > You probably have checked this already, but I could not resist in > mentioning it, did you check the duplex settings on the uplink-router, > the firewall and the switch-ports?
