I'm scrolling thru Newegg for crossover cables to hook up my 360 to my laptop for wifi.

I thought Cat6 cables were better, thus they would cost more, but from the ones I see they're a little cheaper than Cat5e's, so naturally I wouldn't mind saving some money.

I'm pretty sure it'll work, but why not just get second opinions;

Cat6 crossover cable will work to connect to laptop, to connect to wifi?

No need for cross over with CAT6.

The standard of the new NICS includes sensitivity to the type of connection.

If you have old NICS that are Not sensitive to type of the connection use CAT5e crossover.

Hmm, how can I find out if my laptop's NIC is new enough?

It's a Toshiba satellite A215.

If the wire card is GB card, then by default it is Auto Sensing.

If it is 100Mb/sec. card then YMMV, look at the Data Sheet if it say Auto Sensing or MDX.

If you have a relative newer Route,r then look at the data sheet if its ports are MDX.

Only one side of the connection need to be MDX (Auto Sensing), and then you can use CAT6.


:cool:

Auto-sensing was introduced with 100 Mbps Ethernet. According to
http://en.wikipedia.org/wiki/Ethernet_crossover_cable#Automatic_crossover
that was in 1998.

1998 was a loooong time ago. I'd be surprised if any device younger than 8 years will actually not support auto-sensing.

Also, as JackMDX said, only 1 side of the 2 needs to support auto-sensing. So both your laptop and your router need to be very old to experience a problem. Basically, the days of worrying about cross- and straight-cables are over. Hooray !

Auto MDI/MDI-X is optional to implement for gigabit gear, it is NOT required by the standard. That said, I've never seen any gigabit gear that doesn't. But FYI that it's not required and assuming that it's there without testing that will someday find you the one device that doesn't.
