As Ben says, the default for NE is fixed speed and duplex. On MIA unless you've specifically ordered it as fixed, its auto auto on the back of the Cisco.
You need a look at your interface and see if its negotiated at 100 full or 100 half and give them a bell. I've just spoken to them on another matter and they are quiet tonight (following yesterdays debacle) and the night boys (Hugh, Jon, Steve etc) are spot on and a pleasure to deal with. If you need it locked down it will be done in a jiff. Don't forget some of the speedtest.net sites are crap by the way, even at my desk in the DC we regularly see variable results and upstream is always considerably below rated speed. Xilo in Maidenhead are pretty consistent but at my desk I still get 95ish down and 70s up. Get a multi-threaded ftp client and push a few concurrent jobs to a server to get a true indication, or if you have a colo server crack up iperf multi threaded for a true indication. Your downstream sounds particularly bad unless your choice of site was below par, but checking the physical negotiation is your first step for sure. Cheers, Peter Knapp Director C.C.S.

Hi Paul, We have a LOT of VM national Ethernet and I can confirm that the norm is to have to fix each end on 100 Full, not sure on MIA though where they provide a managed router! Regards...
