Re: netgear router locks up ONLY when downloading fedora?

It would appear that on Jun 4, T. 'Nifty New Hat' Mitchell did say:

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

But if I actually knew everything, then I'd know I was an idiot...
