Re: netgear router locks up ONLY when downloading fedora?

It would appear that on Jun 4, T. 'Nifty New Hat' Mitchell did say:
Netgear hardware seems to have some issues when you are moving
large piles of bits.
You did not say what physical layer connection you are making to your
netgear box.
What does mii-tool return?
I have found that my OLD netgear box likes half duplex
with my network adapter. I do not know if my little bug is
in the netgear box, mother board or driver.
For me my little bug is easy to work around by
turning off full duplex.
# mii-tool
eth0: negotiated 100baseTx-HD, link OK
You can change it...
# mii-tool -A 100baseTx-HD
or
# mii-tool -A 100baseTx-FD
This bug was obvious when I was doing an rsync between two
boxes behind the NAT box.
You may wish to go as far as forcing 10BaseT on the connection
as a test or connect to the net directly.
Check with netgear for a firmware update.
Same for the cable modem vendor.
Thanks for the clue.

OK I'm definately out of my depth here... It may be that a
# mii-tool -A 100baseTx-HD
would solve the problem like it did for you.
However when I look at "man mii-tool" the text seems to assume a deeper
understanding than I have of the process...
I gather that this
# mii-tool -A 100baseTx-HD
can be done while the internet connection is running? (should I ifdown
first and ifup afterwards?) And is it something that needs to be redone
every time I reboot the PC or more likely every time the router's power
is interupted?
Also, I notice that the man page said of the -A option
"Multiple technologies should be separated by commas. Valid media
are 100baseT4, 100baseTx-FD, 100baseTx-HD, 10baseT-FD, and 10baseT-HD."
So I figured that the only thing I wanted to subtract from the default
"advertiseing" was the "100baseTx-FD" so using the above -v -v output
as a guide I tried:
# mii-tool -A 100baseTx-HD, 10baseT-FD, 10baseT-HD, flow-control
SIOCGMIIPHY on '10baseT-FD,' failed: No such device
SIOCGMIIPHY on '10baseT-HD,' failed: No such device
SIOCGMIIPHY on 'flow-control' failed: No such device
If the default setting can advertise those media, why can't I include
them in my list of advertised media??
In any case since my router is connected to comcast via a motorola
surfboard, I'm guessing this is all I need to advertize...
# mii-tool -A 100baseTx-HD
restarting autonegotiation...
# mii-tool -v -v
