Hi all,
I have a laptop running window 8.1
I have a pc running window server 2012 r2 (without hyper-v)
I am using a straight cable cat 5e (both side 568b)
I checked my pc ethernet card -> it is using realtek family controller RTL8168E
I go to the website, on the features it states -
Crossover Detection & Auto-Correction
q1) Does the crossover detection and auto correction here means auto-mdix
Both the ethernet card duplex and speed are set to Auto
However, the connected speed is only 100Mbps.
================================================================
Then I use my straight cable to connect to the laptop to the pc.
Now on the laptop, under the ethernet adaptor settings
I set my ip to be 192.168.0.2 255.255.255.0
I set my gateway as 192.168.0.3
On my pc, under the ethernet adaptor settings
I set my ip to be 192.168.0.3 255.255.255.0
i set my gateway as 192.168.02
================================================================
The connection on the 2 computer remains limited and i not able to ping to one another.
What could be wrong ? Did I miss out anything. I have also tried leaving the gateway empty, but result is still the same.
Regards.

I believe Crossover Detection & Auto-Correction is mdix. However both sides need to be mdix, if only one side is mdix, a crossover cable should be used.
Hope this helps.

Hi Cehill,
I went to brought a crosscable today and it doesnt work.
So I went ahead to set file sharing and discovery on both nodes and it still doesn't work.
The lan port led lights are blinking but the network is still unidentified.
I then went to change the cable from cross to the straight one that i use yesterday and it works!
===========================================================================
So i went to take the crosscable to connect to my RT-AC56U router's lan port, there is no led light at all on both the laptop and the router.
If the cross cable is faulty, there shouldn't be led light when i connect from the laptop to pc. But how come there isn't any light when i use it to connect the laptop to router ?
Can i use the crosscable to connect a laptop to a home-base router (with built in switch) ?
======================================================================
So what could be wrong ?!

Odd that is started working.
For each of the connections, what is the appropriate cable type?

well Cehill,
I am not sure what went wrong.
Cross cable between laptop and PC cant work - but have activity led.
Cross cable between laptop and router cant work - no light at all
Straight cable between laptop and PC working!
It means i have auto-mdix if straight cable work, but whats wrong with the cross ?!

Since cross cable between laptop and pc, & laptop and router are not working,
its pointing to a bad cross over cable. Both scenarios, should be crossover.
Pins 1-2 should be 3-6 should be swapped.

Hi Cehill,
Thanks for replying.
q1) I am not sure if crosscable can be used for home-base type routers (those with inbuilt switch) as I have other devices connected to the router using straight cable and its working. Can crosscable be use in this type of router (Asus RT-AC56U) then ?
q2) Guess either i will have to buy another crosscable and try it out or use a network cable tester to test my cross cable .. what do you suggest doing next ?
q3) Lastly, does all interface supporting gigabit uses/supports auto-mdix ?
