I know this is a bit off, but as I never had CAT6 stuff to deal with here it goes. is there any problems in using CAT6 cabling and not 1000baseTX capable switch ? I plan to install cat6 cables and just use 1000baseTX in future. this will be my new home network and all I have now is 100baseTX and two 1000baseT cards. thanks, matheus -- We will call you cygnus, The God of balance you shall be A: Because it messes up the order in which people normally read text.
