Hey there,

I can't seem to figure out mii-diag properly.

I had a 10Mbps HUB on my 100Mbps Ethernetcards, everything was =
functioning fine (at 10Mbps) FTPing from my windows to my linux went at =
almost 1MBps (byte) so that was ok. Now I got a 100/10 HUB so I hang =
that in but the card wouldn't auto notice it, so I did mii-diag -F =
100baseTx-FD (Full Duplex Mode) This seemed to function fine, I could =
download at 2.5MBps now, however when I pulled the wire and plugged it =
back in the LED on the HUB just kept flickering while the PC (IP) was =
unreachable, which made me think renegotiation about the speed went =
wrong, so I set the card to 100baseTx (no duplex), now my downloads go =
at 100kBps max which isn't really what I was looking for.

Now I don't want to restart my linux and the card is compiled into the =
kernel (no modules), still I wanna be able to use the full speed, can I =
set the card to auto detect and just pull the wire and put it back in? =
This didn't work when it was at 10Mbps but for some reason it does mess =
with the Full-Duplex settings... Any ideas as to what I can put the card =
so I can have max performance? The box of the HUB doesn't mention =
whether or not it's Half-Duplex or Full-Duplex or anything else for that =
matter. Just 10/100 is all it says....

Kind regards,

Ferry van Steen
