A cat 5e cable is GigE capable. Cat 6 certainly should be.

5e most certainly is not; 6 most certainly is. You have a very
consistently-observed habit in Usenet of shooting your mouth off about
things of which you know very little, if anything.

Lets see, I have about 20m of cat 5e cable connecting my machine to the
main switch and then 20m m connecting the main switch to another
computers both with Gigabit ethernet cards. I get 80MB/s between the two
(dominated by disk time) ( which is about 600Mb/s) I would say cat 5e is
capable. And the user had Cat 6 wired directly

If I go to Wikipedia on the Gigabit Ethernet page, we get
(http://en.wikipedia.org/wiki/Gigabit_Ethernet)

"1000BASE-T (also known as IEEE 802.3ab) is a standard for gigabit
Ethernet over copper wiring. It requires, at a minimum, Category 5 cable
(the same as 100BASE-TX), but Category 5e ("Category 5 enhanced") and
Category 6 cable may also be used and are often recommended. 1000BASE-T
requires all four pairs to be present and is far less tolerant of poorly
installed wiring than 100BASE-TX."

Now, do you have any other comments to enlighten us with?

isn't there a limit on how long the cable can be (in the case of cat5e)
?
