rtcvb32: Had to look it up.
Crossover cable (
for ethernet), and that's wrong, they are needed if you want to connect one device directly to another device without using a hub or something in between. The networking between the two usually uses static
IP's and bypass the need for anything more complex, but
DHCP is just so convenient.
As for the hub, I have a 10Mbit hub connected to my gaming rig. Network transfer limits to 1Meg a second, but my internet is 200k/sec so that's fine. It also lets me have the PS3 and the rig plugged in at the same time, although only one of them is in use at that time.
As for your present....
NNNOOOOO!!!! I hate coax cables... :P
Crossover cables were only used with 10Mbit and 100Mbit networks and only then for networks that had hardware that did not autodetect the cable or did not have a switch to toggle the wiring of the port internally in the device. Most even half decent switches/hubs had a push button on them to toggle the wiring of one of the ports for ganging multiple switches together rather than having to use a crossover cable between them - just as a convenience. But all but the most ancient network cards can autodetect whether you have a straight or crossover cable plugged into them and adjust themselves accordingly without having to have a specific cable. In other words, crossover cables are not needed with any remotely modern 100Mbit hardware either due to autodetection of the cable or due to the switch present on the hub/switch.
With gigabit networking - there is no need for a crosslink cable at all because while the standards document it, all gigabit hardware has the autodetection functionality making use of crossover cables obsolete.

Owing to the inclusion of Auto MDI-X capability, modern implementations of the Ethernet over twisted pair standards usually no longer require the use of crossover cables."
https://en.wikipedia.org/wiki/Ethernet_crossover_cable#Automatic_crossover "
Although Auto MDI-X was specified as an optional feature in the 1000BASE-T standard,[2] in practice it is implemented widely on most interfaces."
Note in the article that this functionality has been available since 1998, roughly 16 years. The last time I personally had to use a crossover cable with anything was about 2001 or 2002 before I upgraded my network hardware to what was modern at the time - all of which had the automatic detection built in. I've never looked back.
I do have a box in my basement with about 8 CAT-5 crossover cables in it if anyone needs one. They're 12+ years old since I haven't needed one in that length of time so I don't know if they work or not but I'll leave them in a bag on the porch if anyone needs one. :)
